The new frontier for the shops at Harmon: BRASS!!…with the prospect of new tooling in the diecast market shrinking, I’m looking  into ways to have models we might not ever see on 3 rails …..Enter brass models ….much to the dismay of our 2 rail friends, 3 railing some of the finest brass 2 rail models is the way of the future as I see it, …it’s extremely challenging, but the challenge is the juice, …it a lot of unknowns, and alot of planning,…both in execution and budgeting …..you have to be savvy and resourceful all in the same breath,……one of best benefits of doing these swaps, is the great conversations I get to have with good friends and truly some of the brightest minds and historical buffs of the NYC ….Pete & Mario, I really appreciate all the feedback and countless messages back and forth behind the scenes ……..this chapter has truly opened up new avenues, new approaches to modeling, and takes every tool and trick in the book to pull it off right!….the approach….use the best of the best in our world ( 3 rail O gauge ) for this example, the NYC’s H10b Mikado,….it was a gamble from the get go,….I’ve never held one, never owned one,….what’s gonna fit??..what isn’t ??….first thought was swapping Lionel’s Korean built Mikado chassis, a sturdy well built machine, heavy duty, run for years with out a hiccup ……well,….too big, wasn’t anyway shape or form I was gonna cram that chassis up under the H10,….next victim, MTH’s Premier USRA Mikado, …..so I popped apart one I own, and eureka!!….as y’all can see, things are looking up, chassis measurements nearly spot on, and a lot of components in the same places,….so I searched for a deal on a MTH Mike,…..bingo,…my son landed me one the owner said wouldn’t run but was all there,……deal,….when it showed up, diagnosed it’s issues, and made it run ( PS2 3V with a bad tether ) ……there’s not a lot to report to make this fit,…..some minor trimming to clear the flywheel, and other than that, the MTH chassis pretty much fell into place!….the steam chest being the only thing needing heavy modifications, I had to ditch the steam pipes on the MTH steam chest, and modify the saddle ….other than drilling  the tail beam of the MTH chassis right where the KTM’s tail beam was, that’s about it,……the tender I swapped out the KTM trucks ( I really wanted to 3 rail them but they have value for resale so BUH-bye ) for MTH trucks of similar design and there’s that ……the H10’s cab was as naked as a jay bird, so dug through my scratch building junk and came up with a highly detailed back head that clearly needed a good home…….and that boys and girls is how you eat an Elephant……one bite at a time,….Oh, and Bob2 ….this one has to be worth 125.00 bucks !….say it’s so!!…I’ll post up some road test videos tomorrow, or over the weekend if I have time….which I never do….😉

Very nice!  I will look at those photos on the big computer.

I might have missed it - what happens with the leftover parts?

Bob, Thank you!….compliments from you are a truly meaningful!…

leftovers are sold off to the highest bidder,…..and in 2 rail land, that doesn’t take long,.….I’ve got a few of these under my belt now, and I’m beginning to wonder if the parts are worth more than the model!!!…….anyways, it’s a great way to keep a project’s budget from swelling up into the upper atmosphere,…..again, thank you sir!….

Pat another beautiful HarmonYards product rolls out of the shop.  Compared to most of your other upgrades this one appears to be fairly simple.  Seems like even I could pull it off but I'm sure the $$$$$ wouldn't allow an attempt.  Just curious where did the back head come from and why was it the junk box?

It doesn't look like the same engine.  IT looks great!

Great job. I agree. In the future to get a desired model for 3 rail that’s been made in 2 rail brass. It’s either wait it out and hope 3rd rail makes one. Or go this route.

Thanks for the compliments fellas!!….

Coach, the back- head is salvaged from a heavily damaged Lionel Smithsonian Dreyfuss Hudson. At one time, there was a fella on that unmentionable site that sold a lot of Smithsonian parts,….the entire front of that shell was squashed (brass too) I had bought that shell specifically some day to harvest the back-head,…..it was like 15-20 bucks plus shipping, so a lot cheaper than buying piece by piece from PSC or Stevenson’s…..

Pat

Great achievement, but disappointing, in that you had to find a fitting chassis, lucky, vs. three railing a two rail chassis.  Probably no fitting three rail chassis exists for ANY of the models l'd like (except one).. But l hope to see more of this type of effort .

There’s always one,…..disappointing??….are you nuts??….these aren’t built for looking at, or for sitting on a shelf, they’re built to run, and run for long periods of time….without failure, with out break downs, ….this wasn’t a cop-out doing the chassis swap, it was specifically planned to use a modern 3 rail diecast chassis and be able to run the dog snot out of it and not be spitting brass parts all over the place. Yes, lucky the MTH USRA was nearly a drop in, but if it wasn’t, the hunt would have continued, …..chassis from a Connie, etc,…I’m sorry you’re disappointed, ….I’ll try better next time dad,….

Pat

Here’s the shake down video before we headed to paint, …I do need to thank my buddy Lou ( Lou1985 ) for the help on the PS2 3V wiring …..wanting to keep the stock apron on the KTM meant no giant Anaconda tether hanging between the engine & tender…..again, this is another benefit of doing these swaps, it’s the good friends and great conversations with buddies in the know,…..so Lou helped me figure out the best and easiest way to straight tether the system …..runs like a champ!…pulls 35 cars without breaking a sweat!….

Very nice running, Pat!  I'm glad Lou was able to help out with PS2 3v wiring!

Thanks Mark,….I’ll post up another video of the finished product once my graphics guy pays a visit and does all the lettering and cab numbers,…….it’s nice to surround yourself with talent to make a project come to life!..my graphics guy is top shelf, and fortunately for me, ….he makes house calls,…😉

I think what he meant was it was "disappointing" (to him) that the original chassis couldn't be 3 railed (?)

I have zero experience with US Hobbies stuff, but from the look of the chassis in your 4th photo, that big ol' open frame motor looks pretty robust and capable of "dog snotting". 🙂

In any case, another great conversion. 👍

I did watch the video at lunch, but didn't have time to get a comment off. Seems like sometimes lunch lasts forever, today it flew right out the window and no time to wait to get back to the clock.

It does look good coming down the rails all "golden", but this is going to be one heck(I mean the other H-word) of a black beauty. This locomotive has that good look, like all do with their perspective classes, what with the air tank(top front right) at the top of the front of the locomotive. Reminds me of my Uncle Dick's old post war locomotives from days long past. No clue what engine he had that had the air tank up front on it, but I do know he has a lot of the golden post war engines.

I'll be waiting for that other video when you post it Pat. Also, great to see your network of researchers/friends came through like they tend to do when you need them. 👍🐻

Edit:

I would state that the work shown here, makes this engine a runner. That means the world to me. All my engines have to be runners. I don't place any engine on a shelf to stare at. I don't try and keep the miles low for resale value.

If I get the opportunity down the road, I'd love to have a few of my engines corrected. Until then, I can observe the way it should be done.

Oops! I never considered her a brass engine. Funny, she sits here on a shelf too!

and a Weaver that needs attention, and...

I have a couple of 3rd rail engines too. I should have said I don't want any shelf queens. They should all be runners.

Brain fart.

Pat, that looks like a factory finish in the last few pics.. Can you comment on the paint process doing the brass shell. I’ve read many how to’s as far as prepping brass with a media blast to give it some tooth for the paint to adhere to. Always prime first. Or just simply giving the shell a bath in some Dawn and just painting over the factory clear coat. I’ve done a few brass cars using the later method with Scalecoat 1. Any tips would be appreciated.

Dave, …no problem. The paint I use is probably not for everyone, however you can achieve results as close to what I get with rattle can finishes, or an airbrush.

I start by looking the workpiece over for any defects. Repair as necessary, then the next step is a thorough wash with soap and water ( dish soap) . Next step is a time goblin, a clock bandit, whatever you’d like to call it. I carefully scuff every square inch of the work piece with fine grit ( gray) scotchbrite …..then it’s time for another bath. Now my workpiece is clean and scuffed for a guaranteed mechanical bond. Before painting, the workpiece is wiped ( every square inch again) with 91% Isopropyl alcohol. My paint is a 3 part urethane finishing system, paint, hardener and reducer, cocktailed by me for model making. The products I use are mfd. by SEM automotive, and is part of their satin black trim refinishing system. It’s a dead on match as far as I’m concerned, with what the big 3 use overseas….( Scott, Lionel & MTH) …..the products I use are only sold in Qt. form, so unless you plan on shooting a lot of locomotives it may be way too much product for a single DIY project. I shoot the workpiece with a mini HVLP gun at normal working pressures in a controlled booth  to achieve the finish you see ( it’s kinda my job, I paint cars for a living) …HOWEVER, SEM does offer their product in rattle can form, and I’ll gladly post up a picture within this reply for those that want to give it a whirl,….One rattle can ought to shoot a couple locomotives, and the can has a long shelf life. Their rattle can products are also a genuine urethane product, which in my opinion is the only way to go, also and most importantly, these products are a true DTM product, DTM stands for Direct To Metal. So a properly prepared surface needs no priming!!..I’m not a fan of product on top of product, on top of product. It’s asking for an issue …….also, too many products and details are not as crisp and begin to be obscured. Let’s be clear on one thing that is a huge no-no in my world. A sand blasted, or glass beaded surface is NOT properly prepped for painting. Longevity will come back to haunt you on a sand blasted surface. You can blast an area, but I recommend repeating the above mentioned steps for maximum longevity. Sure, there will be those that say they got away with it, but they’re playing with fire ……I have turned a couple fine molders onto the SEM product line, and they are achieving incredible results, as long as the moderators are cool, we can use this portion of this thread as some learning tools, and some “how to’s,….as long as they’re cool, so am I ……so Lou, if you’re seeing this, please post up your rattle canned ATSF pieces ( they’re gorgeous)  and also share your process, which I believe mirrors mine,  but your still on rattle cans,,…we can add more details as warranted, or if Alan Arnold thinks we need to move this part, that’s fine too,….I’ve got no problem doing tutorials ….

Wish I had the cojones to spray urethanes.  They make spectacular aircraft finishes, but require a suit with external air piped in from way far away.

I do bead blast, then Scale Coat, baked at 180 degrees for two hours.  Pretty darn tough finish.

For airplanes I am ok with spraying cellulose based products and limited MEK- solvent systems, but do not do it anywhere near full time.

Cannot argue with the results here, though.  Very nice!

Bob, I wouldn’t argue with your results for the world, ….what works for you is obvious for all to see ….your paint work is stunning,…..I have limited experience with scale coat paints, and don’t know the makeup of the product line,…..I do know urethanes require either a chemical adhesion, ( promoters or sealers) or as in the case of the DTM products, a mechanical adhesion…..nice thing about this product line, right over the bare brass it goes, ….hide is on the first coat, subsequent coats are just a policing action….

The motor isn't the issue. Its the narrow drive train [ i.e. wheels and axle lengths, positioning of the steam chest, steam pipes and the valve gear, etc.] that are the culprits. What Harmon Yards did was the smart, economical, and quick way of solving the many issues of converting a 2 rail steamer into a 3 rail steamer.

Now thats a fantastic conversion. I wonder if the same can be done for a brass Gem models PRR F3 steamer!

That's why I've turned to RC for my 2 rail scale locomotives. Such as this mikado.
