This page from Tony Jeffree (he of the book "The Taig Lathe" and very much more) should be of interest to anyone investigating spindle and surface speeds

Good d-i-y approach.

I've got a nice manual tachometer that I found laying in the dust under the road deck in the Mersey Tunnel of all places. Must have been sitting there for years all in it's box in perfect condition. No idea how it got there but I was glad to find it.

David,

How does it work?, do you have to "stick" something on the spindle. (To reflect the light)???
