Shop wheels

[jaybee]

I acquired my 57 Chevy 2 door Handyman wagon with entirely mismatched wheels, not a good stance to start tearing out rocker panels and doing other work. At the moment the car sits with no interior, glass, engine, trans, or front sheetmetal, just a body on rolling chassis. I've fabricated some 3/4" plywood wheels for it, with a 2" ring glued to the back side to stiffen them up even further. The diameters are the same as I've chosen for my eventual wheel/tire combo. They seem pretty solid now and I even slid one across the floor a bit while jacking up the other side. I've been questioned on the safety of this arrangement, though. Has anyone worked with such a setup in the past, and would you do it again?
