Thanks all. Your comments are a great help. And reassuring, too.



What I gather is that one should pay attention, but not go overboard on the subject. The point that these ships are essentially hand-make was something I hadn't considered, and it's helpful to keep that in mind.



Have Bob make you an HP-24 from scratch. You can even make your own

tail boom.

I would get the exact repair location from 337 or log entry and inspect that area closely. Use a long straight edge like a 48" level, the top, bottom and both sides should be dead straight. Tram the wings using a 50' steel tape. Measure from a common point on each wing (say the outboard aileron cut-out to the probe mount on the vertical fin. These readings should be equal, but don't get excited if the differ a tad, 1/4" is great, 1/2" about average and 1" poor (I have seen 1" difference on a new ship straight from the factory). The tram can be easily adjusted on some ships, LS and Genesis by moving the aft lift fitting out on one side and in on the other, start with 1/4 turn. On other ships this can be done with thin shims under the lift fittings..............excess slop in the main wing pins can be removed by doing this also.
