Mounting an electronic edge-finder

Lambton/NJH,

A variation on the suggestion by TrevorH, thanks, but still has the disadvantage of reducing the distance between the work and the spindle. Remember, this edge-finder is a relatively big old boy - about 150mm overall length, so ideally needs to be nested within a collet as much as possible for stability as much as anything else. By the way, mine has a spring-loaded ball on the business end to prevent damage by all but the most ham-fisted of users! Ordered my ER32 collet chuck and 10 collets from CTC this morning (£66UK inc postage). Should be with me in a week, if previous experience with this supplier is anything to go by.

I'd initially thought of using a standard end-mill holder bored out if necessary but that would suffer the height loss problem too.

The morse-taper of the MT3 blank arbor is generally just case hardened afaik, so it might be possible to bore into the taper a way to reduce the overall height.

In the mind you say .... egad!

Depends how thick the spit is ?

Delighted to say the new ER32 collet chuck and collets arrived yesterday, courtesy of DHL. Only had the briefest of time playing with it, but so far it is at least as accurate as I and my machine can perform. Made me jump the first time the buzzer went off!

edited for spelling!
