Modification suggestions for a Roundhouse 2-8-0? (Conversion into a C-41)
Posted by Safety Valve on Saturday, May 4, 2019 8:43 PM

Hi all, I'm wondering what is the best alternitive way to attach the crank pins on a Roundhouse 2-8-0 kit from the 1980s, the last time (from epericance, the locomotive's crank pins would come loose, some would break and the coupling rods would come loose, I even had piston break) any help in finding a soultion would be fantastic and it would be appriciated! Big Smile

I repainted mine to look like a Denver and Rio Grande Western Locomotive it was orignally red, but I still have to get decal's for the model. I'm not done painting it yet, it still needs a few coats of paint, and another can of vanrnish (I'll go for a gloss for decals) plus the holes I filled in still need a little toutching up. (That won't be needed on the post 1920s model I am buidling) 

I'm also wondering on appropriate Cylinder size and type would work for a C-41 Conversion? it would be appriciated!

The model probably won't be DCC'd (90% sure) , I do have some unique plans for it though! a Conversion to the 3rd rail using a modified Marklin pickup shoe (with brass paper jointers that have the ends cut off) and I will be running the model on Hornby Dublo track that I can import from the UK to the USA... Smile

couplers will be something bit diffrent, something 1960s american  Wink

Is this an old-time 2-8-0, or the Harriman 2-8-0?  Conversion to 3-rail on either one will be tough, as you will have to isolate the shoe from the frame.

Sounds like an interesting project!  I have built several MDC kits with the plastic crankpins you describe. I had issues with one of them, until I realized that the source of the problem was that one of the drivers was out of quarter. Actually, to be exact, one was properly quartered, but the 3 others were not! After putting the four in synch, all worked well. A tiny drop of oil should be applied to each one. I use a tooth pick for that purpose. But make sure the loco runs well before applying any lubrification.

I actually prefer the plastic pins to the screws. MDC supplies more than necessary, so they can be replaced quite easily. Please keep us in the loop of your project. The third rail plan is very intriguing.
