[QUOTE=hemmjo;194360]Got to do what ya got to do!! A lot of people cannot grasp how accurate you can be with a good file. Good technique will remove the same amount it material with each stroke. 5 strokes for each, try the wheel, 5 more in each, try again. Even as the file wears and takes a bit less with each stroke, if you keep moving around the wheel they will be pretty close.

Maybe less runout from the filed holes than from the tire itself. There are very few truly ROUND tires. QUOTE]
When I was a kid, my dad used to mill heads and deck engine blocks with a giant file. No one had better touch his files
