Thanks RV, I noticed that right off... left then right.. naw.. do both.

Trying to figure out the best way to work with wood that doesn't exactly match the plans. BUSA states that plans can shrink or expand due to humidity and such. One plan is on my bench in garage. The humidity has been very high lately. The plan is as flat as can be made flat. Here's the deal;

You can see in first pic (l-r), its reasonably lined up. The nose is on line and the tube holes line up. 2nd pic shows the tube hole lined up. Pic 3 shows the airfoil with the balsa rib to be laminated to the airfoil, still lined up ok.. but as in pic 4, you can see the notches at the top of the foil don't line up, and the slot for the spar on the balsa doesn't line up. Measuring both left and right side foils show both are off the same amount, 1/16th for the spar, and almost an 8th for the spars on top. Yet when I measure a 1/4" part on the plans, it measures 1/4. So if plans have shrank a bit, wouldn't a reference measurement be off as well?

Or is it just the nature of these larger kits, and one has to be ready to deal with any number of fluctuations between wood and paper? Or.. there's a point where kit precision ends and the builder takes over. Just trying to be careful and precise, lest I get down the road and find a 1/16th off one place leads to 1" off later in the build, or something not lining up later because THAT particular slot had to be exact, when should have worked with the offset from the OTHER slot, if that makes any sense... Any sage advice for making sure everything stays 'straight' when dealing with such?

In other news, magnets came in today, should be able to start forming some pieces up next week. Got invited to a weekend of Striper fishing, it'll be fun.. but man.. I'll be thinking about this build the whole time..in a good way!
