Threading Jig

[lorbay]

After talking a Bonnie Klein workshop a couple of weeks ago on threaded lidded boxes, I thought I would try and build one. I think it turned out pretty well and works really nice.

Nice.... Looks a heck of a lot better than the one I built. Works better too..

You have drawings?

Nope just in my head.

How exactly do you use it?

How large a box can you thread? I think that Bonnie's is limited to the size that you can make?

You are limited by the size of your lathe and the ability to off set the box and lid. The original was sized to the Bonnie Klein lathe and was adapted to the Jet Midi (10 by 14).

The cutter mounts in the headstock and cuts against the outside/inside on the Box.

Jet can do about an 8 inch diameter box (4 inch offset) if you offset the mounting box. Most uses are for 4 inch and smaller threaded boxes.


(Have a Bonnie Klein lathe and threading jig - and have adapted it the big lathe on occasion with an XY table)

Here are a few pictures in action.

Ok, I think I get it. So is the thread size determined by the long threaded rod that runs through the center of the jig?

Yes that is right, so you could really make a bunch of different ones if you wanted a specific thread. This one is 16 tpi and looks nice a small boxes.
