edge joining plywood
I'm using #20 biscuits to glue-up several pieces of oak plywood edge-to-edge to form a larger panel. Upon gluing the first such panel there is a problem. The edges do not align flush on the face of the panel.
The plywood varies often in thickness, even though all pieces were cut from the same sheet. I was careful to register the joiner fence against a common face of all pieces. I thought all the pieces would align on that face due to the biscuits. That face was oriented up during clamping and gravity may have worked against me. The glue was also rather old, and probably too tacky.
There are four more of these panels. I got some fresh glue. I'm thinking I'll try clamping with the "good" face down. That will present some difficulties wiping off the glue squeeze-out.
Am I on the right track? Other suggestions for dealing with varying thickness of the plywood?
