i have one of the wobbly type . its slow and labourious to use . I have it in a collet and bring it up to the edge and watch it centre . Then I do some sums . Its 1/4" halved , them to metric . The I calculate whatever distance of travel

You could just try a bit of cigarette paper.

Ok , but what clicks ? Is it a mechanical device ?

I use the dials on the handwheels ..no DRO :no: .

You could always save up your play money and buy one of these.

I must admit I have a tendency to use the yellow pages.

Hi Mike,
Well the 1/4"x0.5 converted to metric is the same number every time. 3.175mm. That should save you some math.

It wouldnt be hard to make a 6mm one

Fisher tool in LA sells what is probably the best old school edge finder still being made in the new world. The old world still trumps that with the Haimer 3D taster that Bob linked (I assume since I am on a less than friendly pad device, and hence will not look)

Starrett's current production edge finders are all Chinois and so-so according to those now ex-Starrett affecianados on the net.

A couple of years back the best edge finders in the world were made by an old-timer for Hermann Schmidt in the USA, but he has left the building, in one form or another apparently. Hence, Fisher is your guy now.

Up this late trying to adorn a fabricated switch plate with engine turning just to mess with Bob's thang tonight. :aro-r:

Well it moves sideways as it hits the edge...

DRO's are magic on the mill...really, really, really really good...

Have you ever measured the Actual movement of the Table in regards to Actual movement of your dials,from my experience with these type machines the increments on the dials are a guide,I have not found any yet that move the stated amount.
When needing to move an accurate distance or depth I use an indicator.
