I need some 1/2" quartersawn oak plywood for a project. No one locally carries the 1/2". Can't use 3/4" or 1/4" for what I need and don't want to do a panel glue up etc... from wood. I was planning on gluing two sheets of 1/4" quartersawn together to get what I need. Plan is to rough cut them oversized and then glue them together and cut them to finished size after glue up.
My question is how much of the surface do I have to cover in glue for an effective glue up? Rather than covering one complete side in glue can I do 2"-3" around the perimeter and then a large number of wide swaths in the mid section and will this work effectively? Since plywood is so stable I did not expect a lot of movement and didn't want to go crazy covering the entire surface with glue.
Thanks.
