Wheels

So, I figured a simple way for wheels. I did a profile of the wheel and used the spin function in Blender. Then I added a line 4'5 1/2" for the new standard inside length between wheels, and some points in the original file for it to snap to.
Now I can use this wheel profile file again with little alteration to create any wheel I need, and still alter it as learn more.
It worked out pretty well.
