I'm going to look at a small biplane project where the major parts are fabricated already. Weld inspection is no problem (for me), but, for everything else, please advise.
How to inspect woodwork?
Tools to bring along - levels, plumb bob, straight edges, tape measure, string, and.........?
Tolerances - there are some obvious measurements - like wingtips to tailpost, to check squareness, but how square is square enough? I know how tight I can hold the tolerance, but what's acceptable to have a good flying airplane, 1% difference, more, less? I heard that Steve Wittman said worry most about getting the wings true to each other.
Thanks for your time.
