Today I broke out my gear cutting stuff, and made gears for the Upshur. These gears actually fit inside the crankcase, but I stuck them on the outside just to be sure that they meshed properly and to take the picture. I haven't had lunch yet and it's 3:52 here, so I'm up up and away to eat something!!!

1. it's a very small core
2. I don't have it on hand..
3. I may give it a try later...
 

decided a core mold that could handle a little abuse was in order,, waxed well, pack filled with extra, clamped together and more sand mix beat in through the 3 openings.. did a little work on the master, filled and thickened the foot, (as long as it cast fully I can thin that section back on the mill.. maybe a pour on Monday..

It's really starting to pop up in 3D now!  It's amazing how long you work on something and then suddenly it takes shape and looks like an engine!

Excellent setup. It seems very sturdy for the carving to come.
I hope you don't need that milling machine for anything else for a while. I just had to dismantle a setup to make some more t-nuts :-(
