Question removal of wood from chuck

I like to turn bottle stoppers. I have the chuck that screws on to my lathe with a stud sticking out. According to the Penn State catalog you are to use a 23/64 drill bit to drill a hole in the block of wood. Then screw the wood onto the threaded stud. I did not use anything but my hands to thread the block of wood onto the threaded stud until it is flush with the base of the chuck. After turning the bottle stopper, I can not get the wood to unscrew. I have tried a rubber grip that you use to loosen jar lids, I tried a cloth towel with pliers. (that only ruined the bottom of the stopper) Any suggestions on another form of chuck to use or am I doing something wrong with this chuck???

Try waxing the threads. You might also try drilling a hair larger hole in the blank. Do this on a test piece to make sure the threads don't strip out. I would try it on a soft wood test piece and if that doesn't strip out then you know you can turn other woods.

Had the same problem with the screw chuck on a Teknatool SN2. What found to be the most effective is a strap wrench like the one used to un-screw oil filters. I made my own up to cover larger sizes.

Waxing the thread wont help much as its force of turning that tightens the bowl or blank further onto the screw chuck.

One thing I used to do in camera repair is to wrap an electrical cord around it. Then you grip this like you would a strap wrench. Try to use a cord that has a high friction housing. It's amazing how many times this worked to loosen stuck filters, jar lids and many other things.

A leather belt usually works well as a strap wrench too. I haven't ever used one on anything like a bottle stopper, but they work quite well on slightly larger objects, and you probably won't have to buy/make a new tool.
