Can anyone recommend a chuck/jaw combination that has a minimum expansion less than one inch? It would need to fit a 1 1/4 X 8 TPI spindle.
When I turn peppermills the top has a hole that is 15/16 in diameter to accept the Crush Grind top. I used to use a MultiStar Titan that could expand into a hole this small. Oddly, the threads on my new lathe are just enough different I can't mount this chuck anymore. I have three choices:
1) Have the Titan chuck machined to have slightly looser tolerance. That won't be cheap, and it may not work.
2) Come up with a different way to securely mount the top on another chuck. That will be tricky as the smallest chuck I've come across is 1 inch, and even a 1 inch hole will not always be one inch after wood has dried and warped.
3) Find a new chuck/jaw combo that can go this small.
Other ideas are welcome!
Thanks,
Scott
