Tool post grinder mount

[Frank S]

This could very well be the world's simplest rotary grinder mounting on a tool post.
Nothing more than a scrap piece or pipe drop, sliced 1/3 of the cylinder away on the bandsaw tack welded the tool shank from a 3/4" sq. brazed cutter with a notched relief for a hose clamp then mounted in a tool holder

I spread the cut opened pipe on my anvil enough for it to slip snugly over my Dewalt rotary tool then held it in place with a hose clamp
