Hi here is a rebuild of a tool found in the encyclopedia :
Here is my version, slightly different, I found a little improvement to make
The front is the same, except I didn't have phenolic plywood, so I made it with outdoor plywood.
Here is the improvement, to get a more clear reference and guaranty that the workpiece is old square to the surface of the table, I enlarged the strut with the handle towards the right, so that it slides on the table.
The assemblies are made as on the original one.
To have a good gliding on the aluminium and steel, I rubbed the sliding surfaces with paraffin wax.
See this article on my website for more details, I have included a demo of making a tenon with it :
