Roundhouse 4-4-2 Atlantic Kit #431 Santa Fe - Looking for a Yoke
Posted by Old Thumper on Monday, April 11, 2016 9:56 PM

I bought a Roundhouse 4-4-2 Atlantic Kit on Ebay, and now that I have started assembly I find that the yoke is missing.  I found the list of available parts on the Bowser site but they don't show any yokes available for this model.  I don't see any yokes on Ebay right now.

Any ideas where I might find one?

The Roundhouse part number is 24103 - also listed as 4L-103 or possibly 7L-103 (the "7L" 4-4-2 kit uses the same yoke)

Thanks

First off, if I am not mistaken, Bowser dose not have MDC (Roundhouse) parts.

Too bad. Missing from the parts list at the Bowser site.

You might ask at the Yahoo mdc roundhouse group. I recently gave away an all metal MDC 4-4-2.

You will have to join.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

Old Thumper:

If you can't find a yoke consider building one out of brass. If you haven't worked with brass before there will be a bit of a learning curve but it is quite doable, and you might just get hooked on scratch building with brass.

Here is a truck I built for a McKeen Motor Car. Its just a couple of different thicknesses of brass sheet, some 'C' channel, NWSL wheels, four modified brass bearings that were bought on eBay and some springs. I'll admit that it took a couple of tries before I got it right:

Don't say "I can't do that"! A yoke would be much much simpler. You could buy something similar to what you need and use it for parts like the axle bearings.

Yes - that is definately an option.  The biggest challenge there is just getting a clear understanding of the part shape.  This is all I have to go by:

Old Thumper.

I'm glad to hear that you are up to scratch building the yoke out of brass. I hope you didn't think my comment was condescending.

Sorry but I can't get your link to work. I keep getting an error message.

I'm assuming that the yoke is for a trailing truck, or am I wrong on that. I'm not totally conversant when it comes to steam terminology.

If I'm correct on my assumption, if you can find some prototype pictures of the locomotive then you would be able to determine exactly where the rear wheels were positioned. You can see from the locomotive frame where the mounting hole is for the yoke so you should be able to determine the overall length of the yoke fairly easily. Given that there were multiple variations of many models of steam engines I wouldn't worry about the exact design too much. Just do what looks good. As I suggested, if you want lots of detail, get your hands on a similar brass yoke with decent detail and scrounge the needed bits from it.

Regards

Dave

Oh thats a bummer! I recently bought a MDC roundhouse 4-4-2 atsf and  it was missing all the rivets and screws for the drive rods. 

Anyways, your best bet is to buy another one as a parts engine, or return that one and find a better, newer kit that has all the parts. It is very hard to only find one part for a kit. 

Good luck!

 P.S. hon30critter the on a steam engine is technically a part of the bell. For some reason, MDC called the cross beam a yoke.

OK - So apparently a steam loco can have nearly as many yokes as a dozen eggs.  The part I need would probably be better referred to as a crosshead guide yoke.  It is basically the crosshead guides and crossbeam all in one unit.  I found a couple pretty good side shots of the same model online, and it will be a very challenging component to fabricate from scratch if I cannot locate one.  But hey - If I make one and use some brass, I'll have myself a "Brass Hybrid" locomotive.  Hot Dog!

:P

You know, I might actually I have another mdc roundhouse 4-4-2. I bought it as a part engine. It has the "yoke" you need...

I dont remeber if I sold it or not...I'll check once I get home.

Awesome!  There are 3 or 4 variations of the MDC 4-4-2.  Only 2 of them have the 1 pc yoke / crosshead guide part.

Thank you for looking :)

Here is the engine that you can have...

(Yes, I know, its ugly, because it is a parts engine, and I didnt bother stripping the paint/repainting it. )

I know its ugly, bad, and dirty. 

If you want, I could make it look better Big Smile
