Default Thread cutting jig using a router

Has anyone seen or perhaps even made a jig that can cut threads in a wooden dowel? I recall seeing a book about routers jigs over a year ago that showed how this could be done but have not been able to located the book again.

Hi Julian

You can get them but I don't know of one for the router.
I have the set from 1/2" to 2" .
G1870 Wood Threading - 1" Die


Just a note ,take it back,,,I have seen a jig to do it with a router, I will dig around and if I find it I will post it.
The Router Crafter may do it also but I have not tried that, just need to make a fine index part for it..
The hard part would be the female part but that could be make on a lathe..

The problem with experience is I usually get it immediately after I need it.

To cut threads on a dowel, there are at least a couple of approaches. The first (and traditional) method is the equivalent of a tap and die set - essentially the Beall and other brands that have been mentioned. Roy Underhill also did a segment on making one, years back.

The second approach is the equivalent of a machinist's milling machine, but using a router as the cutting tool. This requires a geared coordination of the rotation of the stock and the lateral movement of the router. ShopNotes magazine, in vol. 20 issue 115, showed such a router-based "mill" using a combination of wooden gears and an Acme-threaded rod for this purpose. With the right gearing, it could cut threads (outside/male), too, I suppose. One would still need a corresponding tap to cut the corresponding female threads, however.

I use the Beall system. I make my own dowels using a Patrick Spielman type box jig. feeding square stock into round hole with a router above, cutting off the corners. Great fun!
