Rookie question but would like some clarification before proceeding. My plans are Edition 2 Revision 1. I am drafting a form mold on paper before transferring it to wood. On the Wing Nose Rib (75W1-1) drawing, I am assuming the R53 radii measurement is from the tooling hole (190,32) and I have drawn it accordingly. On the plans, however, there is also a spot above and to the right of the tooling hold at x=175mm. Is there a significance to this 175mm mark that I am overlooking? Thanks for your consideration!

Well, that explains a lot and solves some other questions I've been grappling with. Thanks so much for pointing me in the right direction! I appreciate your response, James!

David, the tooling hole has nothing to do with the location of making the radius. Your point from which you draw your radius is at the 175 location, 53 mm up from the bottom line.
