Jointing
From CoMakingSpace Wiki
Jointing (Fügen) is the process of preparing boards with flat and perpendicular sides so they can be assembled and perhaps glued properly.
This task is usually done with a power jointer or a jointer plane.
It may be worth adding a guide to one of our planes if someone wants to joint a lot of boards - please talk to Lukas in advance to see which one would be okay to modify!
