Box Joint Jig

In June 2019 I started a build of the Screw advance box joint jig, a joinery jig designed by Matthias Wandel at

It is a fairly simple machine to build, but you do need to be quite precise so it takes some time.
And for some reason I didn't find the building instructions as clear as for the pantorouter and the bandsaw. But maybe that's just me :-)

Boxes are irresistible...

Getting there

Most of the work is done at this stage. Still to do: the runners, big cogwheel, testing and fine-tuning.
