Keeping busy,  finally got the relay panel built for the 5 signal heads on the signal bridge and installed individual plugs for each head.    As the layout plan has changed due to the planned expansion, I re-did the main line under the bridge,  haven't bent any gargraves track in a while, forgot how well it makes easements, (transition curve).   Will probably go back and do a little more weathering on the signal bridge, but for now I need to run the DC power for the relays, and the signal wires for the insulated blocks.  DSC03076DSC03077DSC03078DSC03079DSC03081

Mark,   Thanks.   Got more complicated than I thought, like most projects.   Since I purchased the do it yourself 3 light LED signal heads, I ended up needing two relays for each head, the first one to detect track presence, then the 2nd one with built in timer delay to control the Yellow to Red change...    In spite of all my "testing the LED's" as I was building this thing, I must have damaged one of the green LED's, not sure when, but what a pain in the ____ to get it off the mast, opened up and replaced.....  Anyway, glad it's done.   

Really want to start laying more track.   My last to do was re-configure the main line on the upper level, had to remove a return loop switch under the signal bridge and bend the mainline

On to Promontory !

Mark, at least you have them neatly under the tables. Mine are all over the place with no organization. I was going to go to Menards to get my PVC but I found a gift card for Lowes I had forgot I bought sometime back. So I got all my pipe, fittings and hardware to do the project. I was going to use 1/2 inch pipe but then decided to go with the 3/4 inch figuring it would be easier to get the wires thropugh the elbows. After I make Chili I'll start working on it. Pic .....Paul

Hey Paul- one of these will bend the pipe quite well, it's a PVC bending blanket ...Image result for Greenlee pvc blanket

I have one and I like Chili......should be out to Ohio by morning

Nice panel Chris. Who made the relay boards?

Bob

Bob,    I bought them both on ebay, here is a link to the ones with the 1 to 10 sec. timers... 

https://www.ebay.com/itm/US-SH...p2057872.m2749.l2649

If I were to do this again, I think I would use the old school type ice cube relays 12 VDC for the first bank of relays (without timer delay)....    The SPDT relay modules I bought 2 years ago are like the link below also available on ebay...   

https://www.ebay.com/itm/1-Cha...;hash=item3d5b46e298

 

Paul, looks like you have a good amount of work ahead! Just for thought, if you ite a cotton ball to a string and use your wife's vacuum you can suck it right threw the pipe!

Chris, things are looking nice, One question why not use a group of relays? I have a few that are 5 per board!

Lee, you are moving fast! But it sure looks good!

Mike, you are always welcome here. My plan for the PVC is to do a section at a time. Feed the wires through the first section then feed the wires through the second section and glue them together and then so on till I have it alll the way through to under the island table............Paul

Paul, that will work, but be careful, if you get to much glue it can melt the wire covering!

John,   There may be other recommendations, but I mentioned buying this one off of Amazon made by "Point Zero"..... It's only gone up $6.00 since I bought mine a year ago.   

https://www.amazon.com/gp/prod...00?ie=UTF8&psc=1

Paul,  I would work for the Chili, looks pretty darn good.   I just came up from the basement, and realized it was getting late for "dinner" !!

Mike,  The 5 pack on one board should work fine,  I had purchased individuals some time back, long before I realized I was going to embark on this 5 signal bridge.   

Cancel my remark above, about using the ice cube relays for the first bank of relays, the one's I used are fine.  For some reason on the test bench the intensity of the Green LED's was changing and getting brighter when I activated any one of the blocks... Now that it's on the layout, that problem is completely gone.

I think my $5.00  HO  -  DC transformer that I picked up at a train show for doing bench work projects has voltage control issues.    I have a real nice Post War Lionel (HO)   DC Transformer on the layout that is powering all my signals, relays and LED building lights through some local inexpensive regulated power supply circuit boards to vary the building lights.   It works great, and there is no change in the light intensity on my new signal bridge.   Need to throw that $5.00 thing away and get another one that I know works.  

Chris,  Thank you for the recommendation of the Point Zero Air Brush.  I ordered it with some cleaner and cleaning brushes.  My air brush from college was ruined when I failed to clean it promptly after use.

My paints for re-numbering some Atlas O Union Pacific Hoppers are also on the way.  I have decals for the re-numbering of 20 of the 22 Trainman 70-Ton Open Hoppers.

My shipments from Atheron Scenics of flexible and rigid PRR Walls and Fillers arrived this week.  My winter projects are shaping up for a busy time.

Today I repaired some of my damaged concrete drive, hoping to postpone the inevitable new driveway.  It has worked in the past, but I was younger then.  Several of the bags from Home Depot had solidified concrete corners, already rock hard.  Tomorrow I will return the unusable cement and ask for a refund.  Contractors return cement all the time.  I got three bags that got wet before they were returned to stock.

Sincerely, John Rowlen

John Rowlen,  Ironic you should mention that experience.  I was thinking after responding,  to suggest that you plan to clean it thoroughly after each use.   The acrylic paints are great for keeping noxious fumes from building up, but they do leave residue inside the airbrush.  I bought one of those nice glass cleaning jars with a bracket that acts as a holder, but when I am done using it, I always pull the needle, and the nozzle end and soak everything in Simple Green for 30 minutes, then rinse it and let it dry while apart.   Got myself in trouble one time when  I just flushed the airbrush cleaner through through the cup, and thought it would be ok till the next day then when I picked it up it definitely wasn't spraying as well as before....  Took it apart cleaned and it was back to normal...  After that I just decided it was worth taking the 5 minutes to take out the major parts, soak, them and then I don't have any issues to deal with.

Thanks Chris.

I used a AC relay for my grade crossing signals. I have some dwarf signals that I built and I'm looking for a better way to control them.

Yesterday I decided to some cleaning / organizing under the layout.  A few months back I took some engines for service to Mr. Muffins.  I was looking for the engine boxes and of course found every one but the ones I was looking for (thanks Murphy's law).  I decided to relocate the engine boxes from under the layout to the attic of the house.  With a little help, I moved over 30 MTH, Atlas and Lionel engine boxes from the basement to the attic.  I then celebrated that by running trains for over an hour last night with 7 trains running and me walking from room to room with my iPad using the MTH WiFi. THAT was a lot of fun.

Here is what I did with my engine boxes so I could find them if I need to ship one out.  Of course you can see I don't have anywhere near 30.  They make a nice little view block of boxes for ceramic buildings as well.

Here are all the rolling stock boxes in the closet  under the basement stairs.  They will go under the new layout once construction allows.  At 62, I'm tired of crawling in here.

Mark,

That is one reason they were moved to the attic.  Getting under the layout isn't the easiest.  I still have another 10-15 to find but thats for another day.

JBMcCormick, I know what you mean about under the layout.  I am planning on using a roll out dolly.  I’m thinking of putting casters on plywood platforms that I can roll out.

I used furniture dollies from the big box store.  Less expensive than buying castors of the same quality.

It seems like years trying to get this layout going. Thanks to you guys for the inspiration I’ve got a lot more done than I thought I could.

Lee, your more then welcome, I also get a great amount of inspiration from this forum! I like to give credit where it is rated!

Matt, Yes that is just it.  Also, besides the cost savings, those make half the work already done for you!  I suppose the person who wants display shelves under the layout could put them on the front and still put a handle on the top front.

There are many options for any layout.  I may paint the fronts black like a tunnel with a white headlight on one & a red taillight on the other. For me I just roll them out when I want to work under the layout. I made a creeper from one of the dollies & it rolls very smoothly. Mine are 3’ x 6’ & required 2 dollies each. I still wish I made the layout 4’ High instead of 3’.
