Hi Matt,
Will do.
I have worked out a glueing method, using PU, that will use 5g to 7 g per skin.
It's just that I have not done it this way before with veil between the wood and the core.
I will do some testing today and examine the results.

On honeycombed large mono wings I used thinned PVA put on the wall caps in a bead with a syringe. The PVA was thinned by 30% and a little food dye added.
10cc was more than enough per skin but when dry this left only 2g to 3g of dried PVA. So I was skinning a large mono wing panel for way less than 10g.
This required that the foam cores be pre sanded to a fine surface finish and the panels had to be put in a cold dark room for a few days to dry out when they were removed from the press.
More later.
