If you had witnessed the simplicity of what Mach b had at the old warren shop on Stephens Rd near Grosbeck.
Big wooden box with a variable RPM spindle for wheel speed testing, a rotary table with a swing arm, and a crusher wheel.
How many wheels would be in a lot ./ would it be worth a local guy to set up a wheel shaping service in a garage shop?
A simple machine might be a Trailer Axle bearing mounted on a scrap lathe bed with a swing arm for crushers, using an automotive flywheel as the rotary table....and a simple lathe for making shape crushers.. a diamond follower for diamond-dressed wheels. Likely fudge up the whole shebang for $500.
The old-fashioned Carborundum 8" x 2" x 2" Dressing Stick makes quick work of roughing in a wheel.
