Any tip to cut out a rectangular notch on the edge of a rib or former, so the spar or longeron fits perfectly, while doing it by hand?
Regards!
Glue some sandpaper to a piece of the proper size of spar you are using on the structure, and it will quickly sand the close fitting notch in the rib or former. Learned this from a coworker who always scratch built CL planes.
In the third picture, I glued the tip and root ribs in place. Used the spar as a guide to park the location on the other ribs. In this case, the spar ran at an angle to the root rib and was able to sand the spar at the proper angle and location with no gap. You can't do this with laser cut ribs.
I'm working on my first scratch built from plans too. Enjoying it immensely.

Thank you very much, Jim.
Intersting solution for the angle notch.
Regards!
