We used to be able to pick up better wood all the time. The sheet on the other side is much blander B stuff. They were 7-8 pound and 6.4 pound sheets respectively. What surprised me was that the two sheeting pieces totalled .60 oz, while the latticed stab, hinges, elevator, and horn attachment pads and dowels totalled only .70 oz. 'sure wish I had more of that C-grain stuff!
I had done pretty well laminating the first piece of 1/16" sheet with CF, except that I thought I 'd have used less epoxy, if it hadn't set up so fast. Nevertheless, I felt that I could still save .1 oz over the previous stab. So for the bottom, I tried a different order of application. I really got caught out this time, and instead of improving, I used noticeably more epoxy, and under weights, it squeezed out over the tape protecting the hinge gap and hinges. That adhered the tape and closed the beveled area. What a mess that was to fix - more or less. So now I've lost the weight advantage and have a bottom I don't like to look at. THEN, I dropped the thing and over-sanded in one place, necessitating an insert and patch. This age thing shows up in a lot of extra work. Incidentally, I'm not sure I'd do the CF veil in the seam again; the edge sands like steel and makes contouring much more laborious, if you want accuracy. It's stiff already, and when the outer layer is applied (FG, CF, or silkspan) it should be over-kill stiff.
Pictures show where I am now, with roughed contouring in progress. Lines are for bevelling equally on both sides to ensure some airfoil symmetry. The l.e is critical for me; so I've learned to get the CF edge accurately under my abrasive block by listening for the higher pitched sanding noise, when my sanding block or file angle is right.
