Default Tsunami - composites, part 2

Quick update for 6/5/02

Pulled the wing halves out of the bag on Tues evening. Came out great! Much better than last time so far. I believe I mixed up 12 oz of epoxy and used approximately 8oz in layup. It's hard to tell because a lot is soaked into the roller, excess glass, and still in the three paper cups I put it in. Plus, the excess that is pulled away by the peel ply is hard to account for.

Last night, I cut and laid up the spar material and put it in the vacuum bag. It's 3/8" end grain balsa with 3oz cloth bagged on each side. Next step is to prepare the landing gear area ribs (they will be much lighter this ime), lg rail supports, etc and install the main spar, along with some sub spars. Should have the mold closed up by the weekend and I hope to be grinning when I pull it out of the mold....

Remember, I said that I thought a 12 oz reduction was possible with this new layup. Last wing was 2lb 7 oz (very heavy!) Let's see if I meet my goal.
