Thread: Thickness gauge

The downward force isn't exactly where drew it, but the effect is the same, i.e. it produces a lever effect and a bias on the gauge. Consider when you make pencil marks for laying out a spindle shape, and spin the piece to trace them all around for visibility when turning, by pressing the pencil against the piece. The force you feel in your fingers is the same to be felt by the gauge. Similar with the older spring steel doodads.

And it ain't rocket science, Ed.

Some brain surgeons gathered to discuss a challenging operation. After they found a simple solution, one of them said, "Well, it isn't exactly brain surgery, y'know. . . Oh, yeah, I guess it is."

Yep, it ain't. I am aware of what you say, Joe, but have you tried marking with the pencil held radially and noticed the difference?

Anyway, I am not a physicist and I can't talk by experience, so I am not in a position to make any forceful assertions. I will shut up now and if one day I'll have the will and the time to actually make one for the hell of it, I'll find out the hard way.

I know enough about geometry to be comfortable with what I said about consistent thickness, though.
