A couple of my mods were done before I got my camera and found this site. Anyway, one of my first projects was to make a bigger, beefier cross slide leadscrew which requires a left hand thread, so, before I even start, I wanted a hand crank for left hand threading.
It's pretty straight forward, the spindle end nut was drilled and tapped for two M6 cap screws, The crank body was tappered on the mill from scrap 1/4" thick x 1 1/2" wide mild steel flat bar and the handle end was drilled and tapped to accept one of my x/y handles from the mill (since I don't run both machines at the same time.
Other than making sure it was short enough so I don't smack my hand on the access door and grinding the ends round was to paint it. Gotta look pro right? After all, when anyone looks at my mods, I want them to think they are 'stock' items.
