Timber Jig Timber Framing Tool
When we were working on the lower frame for the goat barn I made the first version of this jig which you can see below in the video. It was made primarily to make it easier to cut mortice and tenon joints on logs which can be a lot of work to layout and cut compared to a square edged timber. Since that first version, it has gone through two other major revisions and now is as you see in the pictures on this page. As with any tool like this one, there are always improvements and new designs that come to light while working with it.
The frames we have made have a lot of curves and other odd angles which are easily worked with the articulated chain mortiser which can be set to cut at most any angle. Being able to index a log and accurately lay out joints along it’s ends and sides makes incorporating a plain or specially shaped log into a frame much easier.
