>Why make - or buy - Cole Jaws when, for next to nothing and a bit of time you can make a self-contained scrolling chuck to do the same job easier and better. I calculate that there are exactly 40 steps required each time you decide to use Cole Jaws: 8 screws x 2 to remove and replace the chuck's jaws, 8 screws x 2 to fit and remove the Cole Jaws, and 8 screws to re-set the buttons.
A quick addendum to the article at the link, Since writing it I have definitely decided to make another chuck about 10" in diameter, and for smaller work, I much prefer 1" rubber chair caps covered with a flat steel washer for the jaws, i.e. just like Cole Jaws.
