New and Improved Klein Threading Jig Information

have written this to answer questions about using the Klein Threading Jig on other lathes. Hopefully, I have answered your questions. If not, please let me know.

The Threading Jig was originally designed to be used on the Klein Lathe, but it has been recently redesigned to allow it to be used on most of the mini lathes on the market today. The Klein Threading Jig is now manufactured with a 1" - 8 tpi spindle and comes with a HSS cutter and the holder for the cutter. It will cut 16 threads per inch.

If you want to use it on a small Jet, Delta, Vicmark or General - you will also need the riser block to bring it up to the correct height.

For other lathes (large or small) you will need to build your own riser block. We have a mounting plate for you to attach to the top of your riser block. The Jig attaches to the mounting plate. The riser block you build, could be as simple as a box made from ¾" plywood. It must be able to slide along the ways of your lathe, remaining parallel to the lathe bed, and must be able to be clamped in place. The mounting plate comes with drawings for building a riser block.

In all the classes I teach and all the demos I do, my preference is to use two faceplates to make the threaded boxes. There are a couple of reasons for this. I can leave the lid and the base each attached to their own faceplate until I'm finished with the entire threading process. I don't have to worry about returning a piece to the chuck exactly like it was before. I prefer not to use chucks in a class or in demos for safety reasons. It is too easy to push the tool rest or your fingers into the chuck if you get distracted. I like to turn 2-3" diameter boxes between 2000-3000 rpm. I'm not comfortable spinning the mass of a chuck at those speeds.

Also available is a DVD showing how to make threaded boxes.
