My special chuck-wrench design, incorporating a spring-loaded ejector pin, prevents accidents caused by leaving the wrench in lathe chucks. To accommodate the ejector pin and spring, I drill through and counter bore the center of the wrench. The wrench handle keeps the spring in place, but I install a safety collar secured by a setscrew to keep both spring and ejector pin in place if the handle is removed.

Drilling table for milling machines

A steel plate measurin 3 /8 X 18 X 18 in. with a 1 1 /4-in. square bar 8-in. long welded to its back and held in a vise works well as a drill table. For any vertical milling machine, this setup provides drilling with more reach and eliminates having to clear mill tables of fixtures before drilling.
