Here is a Slot Mortising Machine I made mostly from bits and pieces that I had lying about the shop. It is therefore, by far the cheapest machine I have and a very handy addition to my workshop.

I use it for cutting the mortises for floating tenon joints, spline mitre joints and for any slotting work that is required. The machine comprises X and Y tables that run on drawer slides and a router that is mounted in a height-adjustable plate so that I have Z adjustment as well.

There are stops for delimiting the cut distance and a depth stop for controlling depth of cut. Clamps hold the work down and a mirror enables the blind side of the work to be seen.

The mechanism in front of the tables controls the depth of pass (1 turn of the black knob = 1/32″) so there is no stress on the machine or on the work. The machine is a real pleasure to use and is always a talking point when visitors enter my workshop.

    • Just had a look at your video Nick. You have certainly done a superb job. I love it.
      I bet you can appreciate how smooth running this design is and what a pleasure it is to use. I am very chuffed that you considered my design worth copying.
      Thanks for the credits and I wish you many happy hours and successful projects with your machine.
