A simple means to convert an electric plane into a small jointer - good for finishing relatively small pieces of timber
Step 1: Layout and Build
Roughly measure your plane and cut timber (or in this case MDF) to size. The aim is to create a u-shaped frame the width of the plane. I left one piece higher on purpose (by about 2 inches or 5cm) to create a "fence" for guiding workpieces.
I then sandwiched the plane in place, clamped the side pieces and screwed the entire assembly together. This is aided by my plane having two flat surfaces on both sides
Step 2: Mounting the Reference Block
I cut a 30 degree angle on a scrap piece of wood and screwed in place. This references against a piece of the plane with a 30 degree internal angle. This holds the plane in perfect position each time
Step 3: Mount the Plane and Finish
I positioned the plane upside down in its new home and ensured it was square and true to the assembly. I then used short quick release clamps to ensure it can't move during use. As there are no permanent fixtures used, the plane can easily and quickly be removed for hand held use if required.
A note of caution - this will turn your plane into a far more dangerous piece of kit. Beware of fingers, arms, loose clothing etc. And most of all, if you are not confident with this project, do not attempt it. I'd recommend using a push stick or similar when feeding stock through the machine.
