S/N 10 Shay

(1/29) > >>

Dan Rowe:
The real start of this design is the Graham Shay engine.



I had spent a bit of time thinking and discussing Shay shop number 10 when Regner made a model of it several years back. The photo is the only engineering information available except the Lima Numerical Record lists the engine as 8" x 8" and the drivers are 24". All the rest of the engineering information on Shaylocomotives.com is educated speculation based on catalog data.

The photo is nearly straight on so using the driver diameter I scaled it in cad and started the drawing process.





Now I have to think of how I will use each bolt I can see in the photo for a prototypical use. The Lima Shay frame drawings start with steel I beam frames none of the wood frame drawings exist. There are a few key photographs of early Shays that I will show as this built progresses.

Cheers Dan

Always fascinating to see how mechanisms developed. Will be watching along!
