I need a ring gage that has a magnetic base to calibrate the Renishaw probes on our milling machines. Any ideas on where to pick one of these up?
 
Ok, thank you. I don't have a grinder though.....

Bummer. Seems they can be had for not terribly much more than that 500$ ring posted above. And they sure can be handy.

We have a 1.8375 "ring" that is actually a hole ground into a hardened 4x6" appx block that we can throw in a vise or toe clamp to the table. Doesn't have to be magnetic eh...
 
Take a block of alu, set its center to zero, mill a round pocket or hole to it, I use 100mm, mic the hole that its round. Use that to calibrate.
