Does anyone have suggestions on how to drill for offset teeth, specifically, how to make sure that you position them 180 degrees apart?
We have access to a lathe and drill-press, and most likely a mill.
Our current design has 4 bolts as impactors, with two on one side near the ends, and two on the other side nearer the center.
In the past, on wheels, I have wrapped a piece of paper around the wheel with marks spaced out at fractions of the circuference (need to include thickness of the paper when finding the diameter), and center punched it. I was debating trying this, or just going to a two tooth style with the holes in line, because I don't think this would be accurate enough for something spinning at 20k RPM?
I know there's got to be a better way...
