I've done some more on the wheels.
I got the steel tires heat shrunk onto the wheels. I made an arbor to mount the wheels on to turn them to size.

It is a very close fit on the axle bores and will stay in the 3 jaw until all work remaining work on the wheels is done. If I need the lathe I will just pull the 3 jaw off and mount the 4 jaw.
The wheels were turned to .002 more than the inside dia of the steel tires.

I stuck the aluminum wheels in the freezer and let them get good and cold. I then turned on, are you ready for it,SWMBOs' electric cook stove and laid the steel tires on the heating element. SWMBO was there while I did it and I'm still here to talk about it. :big:
I let the tires heat up till they got blue then put them on 3/8 plate steel on a little stool and took the wheels out of the freezer and they fell into the steel tires with no effort.
This is what they looked like after cooling down.

I had to see what they looked like on the frame.

Now I have to grind up a HSS cutting tool to the 3/32 radius called for on the tire tread near the flange. I need to read up on how to turn the treads as well as it seems there are some angles involved.
Thats it for now I guess. Oh I laid out the dimensions on the steam cyls too. Will be working on them soon but I want to make a holding plate to fit my cross slide on the lathe so I can line bore them on the lathe.
Till then I wish everyone a very Merry Christmas and Happy and Joyous New Year.
