I am insane, but then, in one way or another, everyone I know is insane, just not institutionalized. Having a lifetime project is the general idea. I'll do it until the eyes and hands give out. I have no idea how these metric jeweler's sizes compares to English. I even have some miniature taps that I bought from MicroMark years ago that I've never used because I don't have matching dies. I'll keep experimenting with this jeweler's set to see if I can produce something that works. I went on Google to actually find the tap drill and o.d. of these sizes, but didn't succeed...yet.
They have cut a lot of funding to all the state institutions, I think we are all safe for a good while yet!
I think you're right. Besides, there's a lot of folks that should go before obsessive model builders.
I finished the MV disconnects today and epoxied them to the gantry. Before doing that I masked the upper works to leave them natural metal when I spray the whole deal sky gray. I then started building the chain link fence. Dennis Brennan first has you build the jig that will align all the pieces. While the standoffs on the jig were drying I painted the substation site "earth tan" and generously sprinkled "earth" on top. Earth on my railroad is Woodland Scenics fine brown ballast. I know some folks really use dirt, but I'm not going to impose on the other person that lives in this house to let me use the oven to bake out all of the organics likes you're supposed to do. After I lay down the "grass, etc." the brown ballast is not conspicuous.
Here are the MV disconnects setting up. I'm glad I checked them before coming upstairs. Two of them had flopped over. The epoxy wasn't set yet so I was able to stand them back up.
This is the jig plate for the fence building. Screws and nuts go into the holes that clamp and position the vertical and horizontal fence members. I put a granite surface plate on top to hold these wooden standoffs while the Aleen's glue dried. That's the surface plate standing up behind the jig.
Lastly, here's the site getting ready to accept the substation.
Little by little, the layout's bed rock is being covered over with land and life.

Looking good. By the way, your project management skills are first rate, too.
Just amazing detail on everything you do.
I appreciate all the compliments, and especially for my project management skills. While I was technically a "training director" in my professional life, I managed many large projects, made extensive use of MS Visio's Gantt charing capability, and took pride in logically organizing the steps. While I don't go as far to do gantt charting for my modeling projects, I unconsciously lay out the steps in the same logical fashion. As I noted several times before, part of the fun of scratch-building is that what-you-do-before-what is entirely up to you. I love big plastic models with 500+ pieces and the great instruction books that accompany them, but I also love the challenge of figuring all that on my own.
With all the computer stuff out of the way, i first had to do a couple of home projects. The first was repairing the Corian kitchen sink. It had some dings and small knife point cuts that come from occasionally dropping stuff when washing dishes. I did some research on it and got nowhere. So I thought about it for about a year and decided last night to do something about it. First I bleached the dark color out of the small cuts using Clorox in a syringe. I dried it and then mixed some epoxy and micro-balloons filler. I used the filler mainly to turn the filler white. I thought about using CA, but realized that it doesn't hold up in hot, soapy water. Which is why you can't fix china with CA if it's going to be used and put in a dishwasher. After curing all night, I sanded the epoxy down using 180, 320 and 600 grit sanding sticks. They're now almost invisible.
Then I replaced all the packing and bearings inside out Kohler faucet that was leading around the stem's base. I had replaced o-rings on this two years ago and at the same time obtained a complete rebuild kit from Kohler. It was leaking badly so it was time to rebuild it with the kit. No more leaks.
Then it was down to the shop. I epoxied the MV breaker to its base and while it was curing started construction of the chain link fencing. Brennan's kit has a jig that uses strategically placed 1/4" holes which get 1/4" nut and screws. At first, having not actually read the first couple of paragraphs in the instructions, thought the fence rods went under the screws. Nope! They drop into the aligned slots on the screw heads.
I'm cutting the mild steel rods using a Xuron hard wire cutter. It cuts mild steel like it was butter. I then square the end up with a cut off wheel in the Dremel flex-shaft held in the Pana-vise. I found it a bit more challenging than I expect to solder the rods together using the RSU. It has difficulty applying heat to both pieces at the same time. If I grip the parts diagonally across the joint so the current flows through both pieces, it pushes them out of alignment. I may have to revert to an iron for this job. We'll see.
Once the epoxy cured on the MV breaker it was time to paint the breaker and gantry.
I also added insulators and did some minor detail painting (plus adding a logo). I also added insulators to the gantry and with that, all operating apparatus is complete.
The last thing I did today was paint the "concrete" bases and the parking pad concrete color.
I can't glued anything down just yet. I want to drill all the fence post holes in the drill press first, then I can glue everything. I think I'll put in the gravel before running the bus wiring since it will be easier to get into things without wrecking the wiring. We're getting close now. I suspect the job will be done before we head Back East for the Holidays.

It is looking mighty good!
This looks soooo real! It is reminding me of work twenty years ago. Very early in my career I was in technology and software at (W)-ABB, but as I time passed in ABB I realized you had to be in "big steel" to get anywhere in the company - (I often joked that the company did not understand products unless you could paint them). I moved to the product divisions in 1990 and both enjoyed it more and had more success - too much it turned out - everyone wants to be at the top or the org chart with the corner office but its the most boring job in the world. That's why I retired early from it and did something else. The fun jobs are out in the field with equipment like this . . . not in a conference room with spreadsheets and powerpoint presentations.
Fantastic work . . .
I've been lurking here, very interesting, inspiring work. Reminds me of helping Gramps make some pressure/temp gauge parts (rod/arms).
Lee, now you know why some folk just like to paint everything. I think you must have got reverse Tom Sawyer-ed in a way. Oh well, just think about the $tacks of fun you have today though.
We are absolutely on the same page! As I moved up the training management ranks I missed the field more and more. My best job was the first one in industry where I was working directly with the folks on the factory floor, both training and solving processing problems. The more academic the training became the more I became less enthused. I had to be persuaded to do management training. While it was a great professional boost in both rank and $$$, it was significantly less fun to a hands-on person like I am. Now, when I'm in the shop almost every day, I am the happiest that I've ever been. Any pressure I feel is self-imposed.
I'm even getting used to the MAC. To copy on Windows, you use the CONTROL KEY which is the lower left corner of the keyboard. To copy in MAC you used the OPEN-APPLE KEY which lies next to the space bar. Every time I copied yesterday my little finger jabbed at the FN key and nothing happened, then I hit the right one. It will take 21 days. When I moved to Germany they gave me a laptop with a German keyboard. Besides having the German accent keys in regular places, they also reverse the position of the Z and Y. The Y is rarely used in German. My real name is Myles. I was typing MZLES for 21 days before my fingers re-learned the new pattern. Then when I got back to the USA, I was again typing MZLES for about 3 weeks. Very annoying!
Boy... Have I digressed! It's morning and I'm not in the shop yet. When I go I will post again.
. . . Now, when I'm in the shop almost every day, I am the happiest that I've ever been.
Same here. It was worth all those years of crude getting to retirement (even though I am only at half).
I suspect you were saying "Crud" not "crude"... Likewise.
Got into building the fence. Much more challenging than I would like. I first tried the RSU, then switched to the Weller iron with a broad tip and then quickly back to the RSU. Getting the pieces fit was not too difficult. Soldering them the first time was not too difficult either. But when i was attempting to clean up the joints with the sanding sticks, things got dicey. Butt jointed solder joints with thin mild steel rods are not very strong. If the joint got flexed, nine times out of ten, it let go. The joints would be much stronger if they were silver brazed, but I don't have the equipment. They would also be stronger if one bar lapped over the other, but that's not how Brennan's design works, nor is it how the prototypes are built. So I soldered, and re-soldered, and re-soldered again. Making it more challenging is the length of the long side of the substation is 24" which is twice the length of the assembly fixture. So I had to join one finished section to another and keep it going. The first long section is almost done with one more bay to construct. I'm not looking forward to joining sections at the corners since it's soooooo easy to de-solder the adjacent bar while trying to do the next one.
This is the first panel I completed before the middle brace bar at the terminal post on the left.
Here's the second panel attached to the first, with the 2nd panel in the fixture. I have one line post to install on the right end and then the corner post. The last bay is shorter than the rest to fit the base plate properly.
I use weights to hold the bars steady while applying the current to the RSU. As I was moving along the solder joints did get better. If the solder doesn't flow properly right away, it probably won't be a good joint. The RSU can make the metal very hot, very fast which is good as long as the solder flows. If it doesn't, the flux oxidizes and the joint becomes resistant to soldering. It's all about timing. It will take a couple more days to construct the full perimeter. The fencing is bridal tulle and there are eyebolts to hang gates.
I'm also learning more and more about the MAC. I found that you can do all the picture editing I'll ever need right in the Photo Previewer. I don't need Corel PhotoPaint any longer which is good since Corel doesn't make a MAC version and I don't feel like springing for the Adobe suite. Speaking of Adobe, you can no longer buy the software, you must rent it for $10 a month through their cloud. Since I'm a hobbyist and not using it professionally, I really don't like having a perpetual $120/yr fee to edit photographs.

Oh wow! Now you really ought to do an article about how you build that fence. Brilliant idea. Maybe only a few people will every build a substation, but a fence. EVERYONE wants to build a fence. You really should think of doing an article.

I second Lee's suggestion. That is a slick jig Brennan includes. I agree, I would have thought the screws were to hold down the material, but placing it in the slots is slick. Sounds like one must hone his skill and have the patience of Job to build this kit.
Thank you once again for the documentation.
Also, that is pretty slick how you fixed the dings in the sink. I never knew what to do about it. Now I don't have to worry. My in-laws installed a stainless double sink when they had the kitchen remodeled a few years before my father-in-law passed away. Then my mother-in-law sold us the house. I like the stainless sink.
I'm writing articles for O'Scale Mag on the entire sub-station project. I've submitted three parts so far and have been paid for one. I'll include the Chain Link Fence too. Needless to say, unless I have more luck with it, I may not want to publicize it at all. This is a typical event:
If this happened once, it happened 20 times! I spent over two hours on Friday breaking and re-soldering one joint after another. As I noted before, a butt joint with 3/64ths steel rod using soft solder is a recipe for disaster, and disaster struck over and over again. I was trying to position it over the base board to mark the post locations, drill some holes and see how it would look. Every time it flexed a little bit, some joint would let go. Sometimes it was just a cross-member, other times, like the above, it was whole chunks letting go. Finally I got it to stay together long enough to get it on the base. I enlarged the mounting holes so I wouldn't have to put any undue pressure on the fence to get it in. I think I inject Gorilla Glue with a syringe once I'm ready to mount it for good. Gorilla Glue is a polyurethane and expands quite a bit when cured. It would fill up any gaps.
Here's the raw fence on the first (long) side of the base. It's that 24" length that caused most of the troubles.
I tried a couple of different ways to get the solder onto the joint. First I was feeding it from a very fine 60/40 wire, with mixed results. Then I cut chunks of non-lead plumber's solder and put a chunk on top of the joint, hit it with the RSU tweezers and waited for the joint to get hot enough to flow the solder. This worked, but it was frustrating to get the solder to stay still just sitting on the junction. Finally, I started wrapping the cross-members with the fine solder which holds it in place long enough to melt. This method seems to be working okay. Because of the small surface area of the butt joint, you have to build up a pretty large fillet to gain some more strength. The RSU gets the joint so hot, so quickly, that if the solder doesn't flow right away, the joint starts to oxidize badly even with the liquid flux.
If this was jewelry shop, which it ain't, I'd try and laser-weld that joint. That would be the way to do it. If not, silver braze it with a micro-torch. But soft-solder just isn't so strong. If I could make cross lap joints in the steel and multiply the surface area that could work too, but would represent an inordinate amount of work. Dennis Brennan's instructions call for it this way so somebody out there must be successful.
Frankly, I'm not sure what I'm going to do at the corners. Wires at 90° will have to join the same post AND you won't be able to use the fixture since one leg will be sticking straight up in the air. I know that as soon as I get one side on the other will let go... that was happening all day. I'm almost tempted to cheat and have double posts at the corners. Again, if there were lost wax cast sockets (like the prototype) that the rods could seat into, soldering would go much faster. Also, I'm almost tempted to make the whole thing out of brass anyway. It would be much easier to solder. It all gets painted with primer and then finish color so the color of the metal is moot. It would take over 25 linear feet of brass rod to do it. I could still use Brennan's fixture.
One of the values of writing this treatise each session is it gives me time to think, and the more I think about it, the more I'm going to try to use cross lap joints instead of the those butt joints for the bottom rail. The top rail is continuous so it's stronger.

Trainman,
Congratulations on getting the articles published in O Scale Magazine!
Your substation project is certainly worthy!
Flaws and all, your fence is looking better than any I have built. I will follow this with interest but frankly may not follow you in building it: there are some things that are just so dang difficult to do that it is not worth doing it (in my opinion) more than necessary. I've done cheap-shot chain link fences that looked good enough from a few feet away that I left them on the layout. I think I will just avoid putting chain link close up to the edge of the layout where someone can see the flaws. What you are oging through looks quite time consuming and frsutrating, frankly.
Good luck with it though. Great work, as always.
And fantastic about the articles!
Nice use of the Lionel oil rig! I really like it.
I do not recommend trying to make fence sections longer than the jig. I have tried it and the section is too unwieldy. As noted in my instructions, to cover an area longer than the jig (12"), separate complete sections should be carefully fit-butted up next to each other without soldering. The same is true for corners. The prototypical design allows for this without resorting to double posts where the sections abut.
As far as soldering, I'm not a soldering expert and the instructions assume you've never done anything like this previously. If you follow the procedures that I've laid out, one should have no problems. Having said that, Trainman is correct about butt joints being delicate. That's precisely why an individual section should not be any longer than the jig. There are trade-offs when it comes to designing a prototypical chain link fence. Patience is required, however, the end result is an extremely realistic model that will stand up to close scrutiny.

Congrats on the OGR articles, this project certainly deserves to be featured, it a masterpiece!
I too think using the oil derrick looks terrific and I really like that lock and chain! I've only have approval for one article of the series so far. I've submitted three and have several more to go to finish out the whole project. I'm expecting that it will all be published in full, but haven't heard as such.
Dennis Brennan and I spoke on the phone last night about the challenges I was facing in soldering the steel frame for the Chain Link Fence. I really appreciated that he personally answered an eMail I sent him requesting some help. He's a pleasure to work with!
I continued to evolve my technique and have been grinding a small radius so the rod nests into the other piece. This greatly increased surface area and made a much stronger joint.
I've also gone back to the Weller Soldering Station set at #4 with a wide tip. I found that the RSU was unable to heat all of the joint elements at the same time and therefore, caused very poor solder flow. I've also gone back to using the TIX flux, and feeding solder from the spool. The above pic was the last time I used the "solder-wrap" method.
While I was doing this, grandsons were over for nice long work session. #1 grandson is building a 1:350 Trumpeter USS Hornet in Jimmy Doolittle configuration. He's doing this kit while waiting for the replacement Hasegawa F-22 Raptor decals to come from Japan. And #2 grandson did several things including adding vegetation to the area around the substation site, re-doing and adding ballast around the train station, and then we broke open the box holding my Westport Modelworks fire house kit that I bought from Les Lewis at York many years ago.
I hadn't started this model because some of the resin walls were badly warped and I just wasn't sure how to approach it. Today, grandson and I worked out a plan and he executed it. We're CA'ing Plastruct structural parts left over from the bridge building projects. The "I" and "H" beams had enough stiffness to pull the resin nice and flat.
For the long walls we did the same thing. In the pic below, you can see where we had to rip off the side pieces and shorten the cross-member and then re-qlue. The beams fouled the corner when we did a trial fit...Doh!
It may still be a problem because it will be hard to install corner bracing, but we'll figure something out. He learned how to use razor saws, the miter box, CA and accelerator, measuring and cutting multiple parts using a bench stop. Both kids do excellent work and days like this are so special and I know they won't last forever so I take them when I can get them.
We were going to head back East on Christmas Eve day so my shop work was going to end tomorrow, but we've changed itinerary and will be leaving on the 26th so I may get more work this week. Goody!

Because our trip back East has been moved out a couple of days, I actually have some more building time. Today I finished reinforcing the other firehouse wall, cleaned up the mitered surfaces of the resin casting, and then put it back in the box until I'm done the substation.
I changed my chain link fence scheme one more time and landed on one that really made the assembly go together more quickly and resulted in a stronger assembly. While I'm violating Dennis' scheme a bit by using a continuous piece for the bottom and top longitudinal members. I notched them at each line post so they aren't actually stuck on top of the posts, but settle in a bit, but they're still not run from post to post like Dennis suggested. I made an executive decision. I really wanted to get this fence constructed and finish the substation, and I didn't want to get more bogged down.
Here is the cuts that I'm making in the longitudinal members and posts. The two nest together nicely, provide much more soldering surface area and create a much stronger structure. I wish I could go back and do the first one over. I will if I have enough stock or substitute brass for that one side.
I was able to build the 2nd side (both halves) and the 2nd end in half the time it took to make the first section. Steep learning curve!
I laid out the locations of the mounting holes very carefully and because of the much stronger structure, it plopped right in without anything breaking apart.
Following Dennis' advice, I did not attempt to solder the two panels together (each 12"), instead, they're just butted up against each other. I will probably use some CA to hold them after the fencing cloth is in place.
The placement of this long side was based on the short end piece. It had to butt up to it in the corners.
I then laid out and measured for the remaining short side which will have the gate. The gate opening is 4 1/4" wide to accommodate 2 - 2" swing gates. I couldn't help myself and temporarily stuck the base back into its socket on the layout. It's not pushed all the way in since it's hard to remove it, and I didn't want to break anything.
It's also in backwards. The opening will be at the station side. Shown also is the concrete pad that will provide service truck parking. Next up will be the gates, then clean up all the flux and primer paint. From there I will add the diagonal bracing with CA, and then add the bridal veil tulle. And then a final painting and installation. It shouldn't take longer making 24" of model chain link fence than installing a real one. I think the finished fence is going to look very cool and really add to the industrial nature of the substation.

Looking at this I keep expecting a car to go by.
The crop, and the track are the only things holding this back from being indistinguishable as modeling.
All its missing from life is some wind blown leaves at the fence base, and kids exploring the unfinished construction area
Beautiful!
Merry Christmas!
You're doing a great job. The way you're doing the bottom rail will essentially result in same look and at the same time be stronger! Bravo! It tickles me to see you modify my design and run with it. The bottom line is that you will end up with a realistic chain link fence that you're pleased with and fits in with the rest of your superb modeling.
Thanks Everyone, and Dennis!
I had enough material to rebuild the first side completely. It just wasn't working for me and I had three other sides that looked much cleaner. Plus it was still breaking. I then built the gates. Of course I didn't read all of Dennis' instructions about the gates until I was ready to build them and then saw about leaving the end post off of the main fence to captivate the hinges. Instead of un-soldering them and making another mess, i put the eye part of the hinge onto the gate side and did it as Dennis instructed.
Here's the re-made fence, made in two parts that will be butted together upon installation.
You can see that it's nice and straight. I cross-lapped all the joints so, even though the bottom bar sits a little proud of the line posts, it's not sticking out as far as it would if I didn't notch both pieces. I'm using a fiber cut off wheel in the Dremel flexi-shaft which makes it easy to do the notching. Wear goggles when doing this.
Here's the first gate being built.
The solder joints are coming out nice and clean. I use some v-blocks to weigh the pieces down when soldering. This is one application where a traditional iron works better than the resistance unit. I have many tools...each does what it does best.
Here's the first set of hinges in place. I could have done this phase a bit better. It's functional, but not pretty.
Dennis shows keeping the part near the eye parallel and then wrapping the tail around the fence members to stabilize. When I tried this, it distorted the eye's position, so I resorted to using black iron wire, twisted with a forceps, to hold things still during soldering, I had to be fast so the corner connection didn't de-solder. It didn't!
And here's the gates in position for a trial.
Dennis suggests priming all the steel before attempting to CA the remaining details and the fencing cloth, so I cleaned all the joints to remove the excess rosin flux, first with acetone followed up with alcohol. Then laid them out and primed both sides with Krylon primer gray.
This wrapped up work for the day. Not being of the Christian faith, tomorrow is just another day, except for all the stores are closed, so I may get some shop work done. We're heading back East on Friday morning so some of the time will be spent packing, but I might get some stuff done. And for all of you of the Christian faith, have a very Merry Christmas!

Hope everyone is having a great Christmas. Me, I've had a wonderful day also culminating in going to our local Chinese restaurant for take out and seeing a 1-hour waiting line. It's their busiest day of the year. Luckily, takeout came in a normal time. And I did get about an hour's work done on the fencing.
The fence frame is now complete waiting for the bridal tulle "chain link fabric". I was going to start on that also, but then realized that I was about to rush it, and thought better of doing that and went back upstairs.
What was done today was adding the simulated tension rods where the fabric terminates at the end posts, and the diagonal bracing also near the end posts. This was all applied with CA on the previously primed metal.
The fence fabric has to be carefully trimmed taped down on a cutting surface. You need to catch the trim line just above the points on the tulle fabric. This requires a lot of care and I wasn't prepared to spend that much time today. It will have to wait until 2015. Then this whole 5 month project will come together quickly. Of course I still have hook up all those bus bars...
So everyone, until next year, Have a Happy New Year!

Just checking in... got back from our trip back East yesterday afternoon, and today was taking it easy. I got the word from O'Scale Mag that we're going with a 6-part article series on the substation build. I've completed three parts so far. The remaining 9 phases will be folded into three more articles. Tomorrow's going to be cold and a good day to work in the basement. The colder it gets, the more often the heater is on. The more often the heater is on, the warmer is the basement.
Speaking of heaters. We returned to a house that was 51 degrees inside. I had reduced the temp to 66, not 51, before we left. At first my wife suggested that I turned off the heat instead of just setting the temp lower, but after the furnace ran for 15 minutes and only cold air was coming out of the registers, I began to get worried. I checked the unit, opened the panel, it shut off, heard the inductor blower start, heard the gas valve open, and then the ventilation blower start, but no heat and no flame. I have a service contract on the unit and called. The tech came at 8:30 and immediately knew that the ignitor had failed. He had two different ones in his pocket. The one that actually fit was in his truck. Problem solved... and just in time too since it's going into single digits tomorrow. Central heat is like air and water, you don't think about it too much until it's not there.
Tomorrow I'll be back at work finishing the fences.
Glad you got home in time to get the furnace going. We had ours freeze once 30 years ago.
I'm glad to read you got 6 articles.
Congratulations!!
. . . . the ignitor had failed.
For some reason our first floor heater blows its ignitor every year, around the time we first use it - usually November - it goes within a few days of our first using the heater. The heater for the upper floors never has burned an ignitor. . . Anyway we just replace it now at the beginning of winter, every year - the service contract people we have, after about fifteen years, learned and do it at not extra cost now -saves them a trip later - - and we don't go away on a trip until we have, just in case.
A furnace is something you definitely do not mess around with. Mine is cleaned annually. You need that trainroom warm & cozy.
You may want to consider keeping an extra igniter. Its cheap piece of mind. Even HVAC people get stuck in blizzards. Ask me how I know
I think dust, cooking oils, etc. collected on less used ones can crack the surface as they burn off during first reheat. Or you might have a board issue correcting itself after the first repower. Cooking oil seems to be a major reason in my mind. The hot surfaces are oil sensitive.
We do have the HVAC system serviced twice a year at the season change, and I agree that buying an ignitor and having it ready to go is a good idea. It's easy to install since I watched the tech very carefully just for that reason. The weather is really cold today and we're sure glad it failed when it was in the 50s, not the 10s.
Did some errand so I only had a little over an hour today, but it was enough to get some fence fabric installed. It's tricky to trim the tulle so the diamonds are all on the same row. It's very easy to lose your place when you try and align the fabric along the guidelines of the cutting pad. I took my best shot. I used Scotch Magic tape to hold the fabric in place and cut through the tape so both cut edges were supported.
The fabric is held to the frame with CA. Here again, because I didn't fully butt solder all the members, some of them are higher than others so gluing isn't 100% on every member, but enough to support the fabric.
Here's the next piece added and placed into the holes on the base.
You'll notice a gap where the two panels join. That's because there's no vertical post on the one panel so the fabric ends in open space. I'm going to try and glue that piece to the neighboring post when I glue the posts into the base.
There's also one other minor problem which I'm not going to fix. I put the fabric on the inside of the fence. It probably should be on the outside, but again, because of my post/cross-member soldering scheme, the best place to glue the fabric was the inside on the first piece and I was then committed to doing that since you can't have it on the inside half the time and the outside the other half. It looks good and it's not even painted yet. I'm going to airbrush a mixture of silver and light gray to simulate galvanized steel. Spraying will be done with the fence mounted on the base so I can get to both sides and not have to handle it. The fabric installation is 50% complete and will be finished tomorrow. I will then mount and paint the fence and start installing equipment.
I bought some more aluminum small solid rod to use as the bus bars. I'm going to experiment with using the solid or tubular material and see which one works/looks best.

I think the fence looks great. Also, this is a dang good tutorial on making a fence. I'd want to practice some of the steps before attempting one, but the great thing about this thread is that it shows a person what to practice, and how.
Anyway, I think it looks superb. Just great.
Thanks Lee! The fence looks great, but... As usual my great skills are tripped up by overlooking some basic piece of information. The Substation base was plastered into the layout with a specific orientation, and it was set up with the gate on the train station side. Then when I started drilling the base for the fence panels I had reversed the direction. I drilled holes and laid out the entire fence placement BACKWARDS! This put the gate at the opposite end of the base. This would be no problem if the base were completely symmetrical I could just drop it into the plaster socket in the opposite direction. It's not symmetrical and did fit reversed. Therefore, I had to re-locate the entire fence. When I first did this, the gates were 1/4" apart so I had to skew one fence panel to bring them into alignment. Alls well that ends well...
The holes were filled and the non-linear part will be landscaped so the finished job won't be as noticeable as it is now.
So all the fencing is complete. I installed it all temporarily into its holes and airbrushed the whole lot a mixture of flat aluminum and sky gray. The aluminum doesn't show up too well, but it will have to do. I might dust it with some rust to tone it down a bit.
I thought I'd show some more of the intermediate steps to illustrate some of the points I've made over the past few days.
Here's how I tape down the tulle in preparation for cutting. I did find that some of the tulle's edges were sufficiently straight to not need further trimming.
Once the top edge is cut, I tape down the fence frame and then tape the tulle over top aligning the top edge. I put some tension on the tulle do it lies flat. You start by CA'ing the top corner and the edge that touches the tension arm. The tulle doesn't get glued to the corner posts, but terminates on the tension arms. Speaking of the tension arms... the CA is not holding them on very well. Even though Dennis suggests priming first then CA'ing, I had to re-cement them many times. If I did it again, I'd try my best to solder them in place.
Use a very sharp single-edged razor or a new Facto to trim the fabric close to the edges.
For the gate that's 90° to the fence to which it's attached, I added a separate piece of tulle since the gate lay at a different elevation than the rest of the fence. For the other gate that was in line with it's attached fence I covered the whole thing with one piece of tulle, glued it all down, and then separated the gate section from the rest in the trimming operation.
Even with everything glued, it's all very, very fragile. As a result, I'm going to do everything I can to complete the entire project before finally permanently adding the fence.
Here's the painted fence.
After dry, I took all the fence pieces out, filled the errant holes, and cleaned up the base from all the over spray. I then glued down all the operating pieces.
I used Titebond glue to hold everything in place. Since all the foundations are wood, it's the right cement to use. I still have to glue the transformer down to its pad. Since its under frame is plastic, Titebond is not the right cement. I may go back to epoxy as I used on the other pieces. While lying bed last night, I realized that I haven't built the lighting yet, and with all the apparatus in place, it will be a more delicate operation running the wiring underneath. Doh! I should have held off just a little bit more before gluing everything down. That proves that I'm not as patient as my reputation seems to warrant. I am persistent or tenacious which accounts for my ability to keep going. But I'm not patient.
With all the apparatus in place, here's what it all looks like.
So today, I will epoxy the transformer today and start working on the lighting design. I'm going to go with blue-white LEDs since they'll more accurately depict mercury-vapor lighting. I could go with the white-white LEDs if I want to simulate incandescent lights. Any opinions out there? I'm also trying to decide what form and where they will be on the base. I think I'll do some more research on this.

Today I epoxied the main transformer and while it was curing, started working on the lighting design. I'm was going to go with blue-white LEDs since they'll more accurately depict mercury-vapor lighting, but I only have 5mm ones and they're too big. Instead, I'm going with 3mm white-white LEDs which will simulate incandescent lights. After looking at some of my research pics, I noticed they're using some kind of light poles. I was thinking about using some gooseneck lights, but my brass tube was too narrow for the LED wiring to pass through, so I went with a larger 1/8" diameter brass tube which will be a light pole with both conductors going through. I just have to insulate the positive leads. The negative leads can contact the pole. I was going to use the pole itself for the negative, but the upper solder joint wouldn't work as I wanted.
I drew a crude diagram of what I'm doing. The nice thing about LEDs is NO HEAT, so they shouldn't melt the plastic. In the "old" days grain of rice bulbs could not be used in a plastic assembly such as this one. I tried illuminating a Plasticville signal bridge with grain of wheat bulbs in 1958 with not-so-successful results. The light housings melted!
The top and bottom of the fixtures are styrene disks punched out with a hollow punch. There are two sized disks. These are the large ones (9/16") along with the punch that made them. I also punched out the inner disk with a 7/16" punch. These two are glued together.
The inside of the top is now reflective by adding some Bare-metal Foil. I'm making the "glass" enclosure with .005" styrene sheet wrapped over itself and glued, then captured between the inner disks. The way to apply these thin adhesive foils is to lift up a bit on both sides, attach it to some scrap paper strips which lets you carry the foil and place it without it curling and folding over on itself. You see the strips in the pic before trimming the foil around in the inner disk.
It was a bit dicey getting the enclosure glued properly. It takes a very tiny amount of solvent cement. My first attempts melted the plastic clean through. Surrounding the clear styrene is some Scotch Magic Tape to give a frosted appearance and diffuse the very bright LED light. I'm wiring the four light fixtures in pairs so I only need one 330 ohm resistor for each pair in series. I'm going to have to drill holes in the base with the apparatus all mounted. Doh! However, I tested the whole deal and everything is very secure so I will be able to tip it over—very carefully—to do any wiring underneath. Wish I would have just planned this a wee bit better...
I made a lot of plastic blanks for the enclosures so the gluing will get better. I first tried to make the "glass" wrap around once using the inner disk's diameter and Pi, but it's way too springy and would be difficult to install. I then added 0.100" inches to the length to give some overlap. I clamped it with some spring tweezers and used the Touch-n-Flow glue applicator, but it's putting too much on. I'm going to with a fine paint brush for the rest of them. Here was a mock up that I slapped together to see how it would work. I didn't have the Scotch Tape on this one.
Right now I'm going to find some "High Voltage", "Do Not Enter" signs on the Internet and print them out for attachment to the fence.

Worked on the lampposts today. I went to a larger sized tubing so all the wiring, solder joints and shrink tubing would fit inside. I only had one length of it so I could only make two posts. I'll get some more 3/16" brass tube tomorrow to make the rest. I'm wiring two in series and it needs a 330 ohm current-limiting resistor for the 12 vdc input voltage I'm using to retain the 20ma current through the LEDs. Here's one being illuminated.
It's hard to get a good exposure of an illuminated object using an iPhone. They do throw a lot of light. In real life the light is not as diffused as it shows here, but it is diffuse enough to hide the imperfections in the clear plastic enclosure.
I have some questions about posting on this (or any other forum). When we put pictures up on the the forum, whose property are they? Are we giving them ownership of our work by the act of posting? In other words, what are the copyright rules regarding posting on forums like this? If by posting we're giving tacit approval of ownership, I may have to reconsider what I do here.
On a lighter note, I had a visitor on Sunday. The five-year-old son of a colleague (and his dad) came to see the trains. He also visited last year, but it was a little overwhelming. This time it was all "Wow!" and "Cool!". His eyes were popping out of the his head. I'm going to donate the entire set of "I Love Toy Trains" to him. My grandsons at that age were obsessed with them.
While running the trains, we detected a defect that kept derailing my N-S F7 Demonstrator hauling the passenger train. There was a vertical misalignment between the outer loop track as it crosses the swing-gate hinge end. It measured 0.045". Instead of attempting to pry up the track and shim it, which would be difficult since it's all ballasted, I took advantage of L-girder construction. I made a 0.045" thick styrene shim, loosened the two screws holding the cleat to the OSB sub-roadbed, put in the shim, and tighten it up. Misalignment gone.

Smart. Good thinking.
Your substation, as ever, is looking spectacular.
