Machine Production Techniques - Lesson Ten

Today's lesson was mainly used to sort, mark out and cut the timber which came in this morning to sawn lengths. This was then stickered and stacked to allow it to dry. I also began on the legs, and the first thing I did was to create a face and edge. After this I then thicknessed each leg to the correct dimensions.

 I then spent the rest of the lesson marking out the mortises ready to cut out. We then show how to use the mortiser. This is a machine which has a drill piece inside a square cutter. When you pull down on the arm it first drills a hole, and then the cutter slices the wood to leave a square.

The Mortiser also has a bed which can be adjusted from left to right and front to back by two wheels, allowing you to make multiple mortises or long ones without have to un-clamp your work every time.
