>Yes, I think it would work to re-die the thread and/or add a sleeve over the top after you do so. In order to add a sleeve, you would need to make enough clearance by removing some from the threaded screw portion, and some from the threaded nut portion. Without seeing a pic, hard to tell. Wylie should be able to find a machinist in SoCal, they're a dime a dozen down there, could be the machinists capitol of the U.S.

Wylie, If you try it yourself, remember to continue to lubricate as you cut, WD40 should be ok for that, it is commonly used by machinists. Also, don't try to cut too much, only take 3/4 to a full turn, and back it off before you continue to cut more. Taps and dies are easily broken, I have a tap stuck from one such similar event on a fixture I use on my mini-mill. Lubricate after ever few turns at minimum. It might be possible to buy a threaded sleeve, I don't know. Otherwise you could jb weld or epoxy a sleeve in place so you could tap it.

Can you post a pic?
