Where did you get the wheels and gears?

Wheels came from Gary at http://www.sierravalleyenterprises.com/
Wonderful service and a really nice guy!

Gears (and so far the most expensive part) are from http://www.sdp-si.com/
As far as i know, the only place in the USA to get neat stuff like that.

Thanks Russ!

Marty -
Have you seen the Shay thread by another "mad machinist", Dan Rowe, on the SE Forum (www.7-8ths.info)?
He has done a lot of CAD work from original Lima plans, and even some 3D Printing for a
model he's building. Not sure what size, but he calls it a "Mapleton Shay"Australian prototype
maybe? Here's the thread...  http://www.7-8ths.info/index.php?topic=1357.0

Great job so far, BTW...

Marty, absolutely wonderful, I liked your opening comments about your methods of drawing and machining as well, We need to keep those skills alive.
Brass does have such a crisp Victorian quality to it, especially when mixed with mahogany.

Carlo,
Yes, Thanks!
I had seen the "other" thread.
Unfortunately the author was not very helpful, I did find he had "plans" published in some magazine whic I have ordered back copies of.

Michael,
I was thinking walnut!.......

Barney,
Thanks! But I am just a whacker!

Working on what is known as the bottom bracket, basically the crankcase.
This was one of the few items i had no blueprint for, and did not fin any good drawings anywhere.
May be the articles mentioned in my reply to Carlo?

Anyway using the crankshaft drawing and pictures i drew up my bottom bracket.
I need some 1-72 threaded rod to bolt down the mains and then I can mill the bore for the crank!
The block of aluminum is 1"wide x 1.75" long x .883" tall.
Back holes are 0-80 the center is 2-56.

Work continues on the "bottom baracket"
The three large hex (2-56) bolts are caps to allow oiling of the main bearings.
Couple more steps before this is done.

I can not understand how people have the skills to work with metal like that.
It's a modelling area I can only look at with WOW.
:o

Nothing to add, it's way beyond my skills and abilities.
Just wow. Fantastic.

Despite Alexandre's and others' positive comments, I think your work is horrible, Marty. Dreadful. Disgusting. Wretched. But, compared to most of what I see, it's really not so bad .... -- Russ

Yeah, way too much thought and craftsmanship in this stuff ... shame you couldn't just slap some crap together and call it done ... guess it will have to do.  -- Dallas
