A fellow turning club member spent a day in my shop and we set up and played with his threading jig. His jig is mounted to a dedicated Jet mini. It seemed to be the cat's meow for threading lidded boxes. Bill left the jig with me to play with. I watched Bonnie's dvd and saw how effertless she was able to make the jig work. Bill's jig one was stiff and hard to use so I dis-assembled it, cleaned it, put lube where needed and put it back together. Much better, but in order to keep the movements smooth and realitive effertless some of the adjustments had to be loose resulting in non parallel presentation of the work piece to the cutter. I eventually made a couple boxes with decent threads but all the fiddleing around was just way too much for me.
For those of you that own a Klein jig did you have the same problems? How did you overcome them?
