Hi Bill,
Having never used an edgefinder - what is the difference between straight versus curved edges and what features in the different styles of finders make one more suitable than the other?
The Moore Edge Finder sits on the edge of the part not in the collet. It uses a dial indicator to pick up the edge. When you get 0-0 you are at the exact edge.

You have a Moore edge finder?
I have a Moore rotary table.
Unfortunately, it's so darned heavy that I rarely use it.
Yup, I got in in a buyout from a machinist leaving the trade. He modified his with the two holes in the back. They hold two small magnets. I don't use the magnets as they pick up small chips and you are continually cleaning them. The Moore edge finder is as accurate as you can get. Once you learn it Darren it is probably the easiest to use.
The chair type like Bill has (mine isn't a Moore ) takes longer to use, but it is more precise. The Starrett is very quick and precise enough for most applications. It lives in the coolant trough on my vise, so it's always within reach.
The Starrett also does a great job of picking up holes (larger ones better than smaller ones). I've checked it against my co-ax indicator and it works amazingly well.
