I pre heated the room over night and we maintained 26C throughout the layup. This took 9.5 hours with Miachel and myself the whole time and Darren able to stay for more than half the time.
The first pic is to show you the cross threads. Once the cloth is down a key thread is taken out all along one edge which releases the cross threads. These you can see being removed in Pic 2. Once they are out the fibres can be layed up flat but there are also 'free' so it can get wild if you are not in control.
BTW the online log doesn't show 'partners' where as the PC log software has a place for this... so for the record. Thanks to Darren Crompton and Michael Wood for their expert collaboration on this layup.
With Darren mixing epoxy in 130 gram batches we got each piece down, fibres as straight as we could get them and then with warm resin poured on we all just went at it with the 3" wide squeegies. It was amazing how much pressure we could apply to the .025" thick UNI tapes.
Once we got the hang of it things went relatively quickly. We really got all the air out that was possible and all the excess epoxy as well. It was easy to see as we went, it just takes a while despite moving as quickly as we could and still getting it right.
I feel very good about the quality of the spar cap, we can improve slightly next time but the result shows no trapped air and a really solid piece.
