Ron, I bought the castings from a guy in New Jersey who I think tried to start this project but gave up on it either because of the cost or the lack of drawing to machine the parts. The castings were a Yankee Friends set from before or just after the 2nd world war. There are some castings I don't have like the smokebox cover and some of the bronze castings for the crossheads etc. Doesn't matter, I'll machine them out of bar stock and try to make them look as much like a casting as I can.
I have generated probably 40 detail drawings off of the assembly drawings from Yankee Friends and still have maybe another 40-50 drawings to make. The assembly drawings were done by Lester Friend and are really good and very accurate as I scale them to make the piece parts drawings. The nice thing about CAD is you can fit the pieces together on the PC and make adjustments if needed before you cut metal .
Bernie, I still have to finish the Baker valve gear linkage and main rods to see what kind of issues I may run into with the steam chests and cylinders. Hopefully things will go well on the first time around. Things may have to wait till fall though, Ma has a honey do list for the summer.
Thanks Guy's
