My 1978 Craftsman loping sheers have a loose handle so I decided to drill and bolt them together. Using a drill press at 300 RPM and cutting oil for lubrication I managed to kill 4 HS dewalt bits and one titanium while only making it about one third the way through the 3/16" tang. Damn that is some hard steel.
I managed to secure the handle using a self tapper through the hollow shaft and tightened against the steel tang but I know that is going to last very long. It will do for a few jobs
Trying to make a hole for just a small machine thread 2/16 or so screw? Any suggestions?
