An electronic edge finder...lol/
Iv'e been doing a lot of picking up edges on the mill lately. And basically using an indicator is a bit of a pain in the arse. The edge has to be picked up within .0001, so a traditional edge finder falls short. Maybe a brand new clean 100$ herman smidt edgefinder with lapped faces might pull it off, but one tenth is asking a lot. So I ordered an electronic edge finder. I got the cheapo enco model, 40 bucks. reason is I want to prove it out before I blow 150$ and it's the only one I found 6" long, all the rest are 3. After subtracting the 1 inch pickup area, and the 1 inch hold, not much left. battery included.
Anyway, it lights up when contacted. has a spring loaded ball, etc... I guess you could spin, but a safer way is pickup, rotate 90, pickup again, difference is tir. Add half that to the ball radius and all should be perfect?
I wonder if the magnet I machine on will suck the spring loaded ball in?
hmmm...... Damn... Ok, i got shutoffs im milling, angles that have to be perfect...and that thing might allow me to inspect in the machine. I could bump a wall and a floor and have a reference. then bump the angle from a position I drew on the computer. poormans probe I guess.
