I used a moto tool with cutoff wheel to take the steam dome off but kept the sand dome. I believe Weisman's boiler would make a large Shay, unless you want such, keep the HO boiler and live with it. Of course, this is your model, whatever you decide is the way to go. A 20" gauge Shay was a very small thing...maybe 8 tons.

I have a couple of those "Backdate" boilers. Using my 1/48" scale rule on one I get 30 inches in diameter and 10.75 feet long.

Only you can decide if that is big enough.

I'm just gonna cut of the steam dome with a cut off tool . I wanna keeo this shay very small and unique looking so the back dated boiler might make the shay to big for my liking. Looks like I'll have to get a Dremmel of some sorts! My rotory tool is a ten dollar knock off that lacks a lot of power to cut things cleanly. Photos coming soon. I just realized I have a ton of projects going on right now..

-On30 shortie boxcax, my on30 layout, on30 porter bash, on20 shay, O scale saloon scratchbuild. I've caught the "bug" I guess!

I plan on building an On20 shay myself! I've only recently come across On20 modeling and find it rather interesting! So I have been compiling a few On20 loco concepts I plan on building. Here's a concept of the one I'm planning for myself.




I hope you like! By the way, any progress pictures of your project thus far?

Hello!

Progress is going slow on the MDC shay project; waiting on NWSL regear and new bull wheel. I'm also throwing the idea around of getting a flat can motor to replace the open frame motor it came with. I'm also working on regearing and tuning the engine of a Roundhouse Climax loco I bought. Here is my question: where can I find info on installing DCC on these older locos? They are pre-DCC so I guess I have to "hard-wire" the frame(?) and isolate the motor from the frame(?). Thanks guys! Pics coming up of the boiler and frame that I just got done filing and polishing. Till tomorrow!

Hey Man.
Don't discount the value of the razor saw when dealing with modifications to castings.

On your MDC shay project, if you just want to add some height to the steam dome, you could just cut it roughly in half horizontally and add a piece of tubing to raise it to whatever height you think is right.

Regarding DCC, you just have to isolate the track from the motor, and use the decoder as the interface between the two.

Hi all,

I have collected several of these kits (sadly unbuilt as well as a RTR MDC that likely needs a rebuild), and more importantly all the RMC and MR articles. 

I also am a member of the yahoo group dealing with MDC builds.  They have scanned instructions there as well.  The out of print book is really helpful and  pops up once and a while on ebay usually selling on ebay for $35-55, or check amazon or alibris although they gouge at the $135!.

http://groups.yahoo.com/group/mdcroundhouse/

This site has an enormous amout of MDC detail and pictures and is carefully documented on the build, albeit HO.

http://www.modelrailroading.nl/ProjectShay/ShayIndex.html

This site is for a live steam model but has great info generally.

http://www.nelsonslocomotive.com/Shay/shay.htm

Here is a free rail threadon building an MDC shay.

Lots of archive material--NO TIME!

Howdy Tommy...all those links to this & that are cool...but you will never get a locomotive built until you stop reading all that stuff and actually get to work. I built my little On20 Shays over 10 years ago and never looked at any how-to's, etc. I did replace the kit gears with NWSL gears and Sagami motors, but this ain't rocket surgery, it is blacksmith work. Life is too short to sit and contemplate what to do. I jump right in and do it, even if it turns out like crap! Only my 2 centavos...
