I was going to use vacuum after laying down glass for the two halves. For this I thought I had ordered peel ply and a vacuum pump. Without going into the details of why, I had not ordered them. Just ordered both from China today, but they will arrive by the end of the month at the earliest. I cant wait that long, so I will make the first plane as a wet in wet hand layup without vacuum. The biggest difference will be that I cant use balsa without vacuum pulling it down. I will use extra spars instead.
