I have a need to drill some larger diameter holes in pieces set up in the lathe chuck. I use a drill chuck on a taper in the tailstock. Over the years I have spun the chuck on the taper a few times when the drill catches in the work piece. Not a good thing but what is a guy to do?
I had that problem tonight drilling out some 5/8" nuts with a .6195 dia. drill. All the chuck wanted to do was spin. Especially when a little bit of chatter freed it up. I needed to fix this so I could finish a job.
I dug thru one of my scrap aluminum drawers and came up with this... A slip collar from a computer shaft.
It fit perfectly over the nose of my drill chuck.
I thought oh man this is doable!
I grabbed another piece of scrap aluminum. 3/16 thick, laid out a pattern off the top of my head and cut it out on the VBS. Smoothed it off with a flap disc and some ScotchBrite and here it is.
Drilled and tapped three holes in the collar and dog and bolted them together.
