Hey fellas, Made this collet chucks today.Watched a youtube of a japanese pem maker use one.
Had to make a tap 1 1/4 x 8 RH ,too cheap to buy one.
Roughed out a Maple cylinder, then drilled the bore for the tap 1 1/2" deep x 1 1/8' dia
Mounted on the lathe, faced then bored to size.
Cut the fingers on the bandsaw, almost to the thread bore.
mount it back on the lathe and profile the outside,smaller at the headstock.That way you can just push the ring backward to unlock.
Made the ring from ironwood.Bored it out and cleaned it up to fit.Profiled the outside and parted it off.cleand up the otherside .
Massage the bore out with a drum sander for a final fit.
