Marty Chapman, a member of the Buckeye Woodturners and Woodworkers (and my brother) travelled nine hours by car at his own expense from Ohio carrying his Jet Mini Lathe and tools to share his knowledge, interest and experience with our club.  Thread chasing by hand is a tedious, cumbersome and difficult chore.  Marty chose to bring his expensive and more accurate thread chasing jig for a "simpler" demo.  Parenthetically, Marty generously waived his usual fee and expenses for our fledgeling club and it only cost me a couple of meals and a Manitoba Maple Burl.  Thanks Marty for an entertaining  demo and some valuable lessons.  Ken Waller contributed the photos for this page.
Marty's Canadian Made Jet  Lathe.  Tailstock is replaced by Bonnie Klein type threading machine.  Note the adaptor for the chuck.  Princess auto has a version of this machine for metal turning that some of you engineers might like to try to adapt..
After accurately determining center of the stock, the blank is mounted on the club's lathe.
The blank is smoothed and the lid and body sections marked.
The body is parted off and the lid is ready for hollowing.
Close up of the business end of the threading tool mounted in the headstock.
The hollowed top is mounted in the Jet by simply removing the chuck from the club lathe headstock and remounting it on the fixed threading machine.  Marty is about to thread the internal lip of the box.
He first cuts a relief at the top of the lip (not shown)
The cutting wheel in place.
Moving the wheel out in small smooth increment creates the internal threads.
The body of the box has been hollowed slightly (time did not permit complete hollowing), and again the chuck was remounted on the threading machine.
After a relief was cut on the outside of the inner lip, the thread was cut in two passes.  The first pass is seen in the above photo.
Refining the details  on the outside of the box.  With the threads, there is no need to bring up the tailstock for finishing.
The finished box completed within the allotted time.  Had there been more time, no tool marks would be obvious.  The finished product was donated for the club 50/50 draw.  Thanks again Marty!!!!
