Woodsmith Shop-Made Threading Jig & Canisters Plans

In the pursuit of making a set of perfectly matched internal and external wood threads, this efficient and flexible jig delivers the goods.



When it comes to cutting threads in wood, there are a variety of pre-made threading kits available to purchase. Most of them are pricey and don’t offer a way to make large threads. This shop-made system offers cost savings and the ability to create large threads. The jig is a little like a lathe inside out. Attached to one end of the base is a router that’s held in place by a carriage. Opposite the router is a platen carriage that’s made up of two halves. These halves close around a length of Acme threaded rod. Epoxied to the end of the threaded rod is a platen. You’ll do all the thread cutting — internal and external — with your parts attached to this platen. Once the platen assembly is locked into the carriage, it’s slowly rotated by hand into the spinning router bit.
