Ouch!
sorry to hear that Greg. I'm not entirely sure what you mean but it doesn't sound good. Were your wing panels uneven or warped before joining?
In my case, one of my wing tips was warped up due to the long time between the partial build and the finish of the panels. There was nothing built into the wings yet to prevent them from warping (only partial sheeting and no cross braces) and they were subject to repeated changes of temperature and humidity over the years. It wasn't serious however and I was able to correct it by weighting the wing properly and having the covering straighten things out. Of course, had I paid attention, I would have noticed this before sheeting the wings!
I haven't gotten around to cutting any cores yet as I've been working on the Tipo's. It's just a matter of taking (finding) the time to do it. When would you like to return to working on the Tsunami (and the cores)? You probably already know this but shipping of cores is pretty steep these days just because of their size.
David.
