  • Quick and dirty 4-jaw set-up

    Hey all,

    I don't do much work with the 4-jaw chuck so any kind of "cheat" helps me.

    I use a little jig to hold a stack of fiber washers while drilling the hole out from 1/4" to 3/8". It works (worked) great until I ran out of the large quantity of washers I'd been using finally, and started on a new batch.

    The new ones are a few thou bigger than the old ones so I decided to enlarge the hole in the jig. I used a steel ball bearing that I've had hanging around for years and seated it in the hole while being held in place by the tailstock chuck. I brought the jaws into position while rotating it to make sure I was staying in contact with the tailstock chuck and....ta-daaa.

    I'm sure it's old news or common sense for most, but for me, this Q&D method saved me some time and probable frustration so maybe it'll help someone else.

    Thanks for looking!

    Good thinking, if quick and derty works do it.

      In stead of the 3 jaw chuck, a center with a hollow cone (I forget what
      those are called) would be even easier and maybe more accurate.
      That is very good if there is already a hole in the work.
