Two projects I found online...

I found these projects on the web site of a machinist group from Upstate NY, Upstate New York Home Shop Metalworkers
http://www.gooseberryfarm.com/metalworking . The site is still there, but has not been updated in quite some time, so I copied these PDFs if anyone is interested:

I like the clamping fixture. I'll start mine at 1/4" and go up from there because I can cut the smallest three with my wire strippers.

My centering tool is a piece of 5/32" music wire with a point ground on one end. I chuck it in the tailstock and wind it into the center punch. It doesn't have the advantage of the spring, but I might just add that. I just added an RC wheel collar near the pointed end to give more surface for the dial indicator.

Thanks, Nelson. Good post.
