Ellectro - mechanical tachometer

[Paul Jones]

Marv,

This would still be a great addition to any small lathe and the disk could have a double duty for mechanical indexing with addition of a locking detent pin (e.g., the HRSP model from J.W. Winco, Inc. Website and Online Catalog).

I looked at your other tools you posted on PhotoBucket and a very impressive collection (many not posted here at HMT).

Thanks for the ideas.

Paul
