Building the doors for the built-in hutch required that I go out and buy myself some more tools - a mortising machine and a tennoning jig.
How to drill a square hole? Get one of these!
In the above photo you can see the stem for when I need the lever on the right side. But I'm currently using it on the left side, as shown in the photo below.
There ain't much sense in making perfectly cut mortises if the tennons aren't equally perfect. For that I got meself a tennoning jig. Had to tweek it a little to work on my saw, but it works real well.
I'll be sure and get some pictures of the mortises and tennons as I put the doors together.
