I want to edge-glue several boards together to make a wider board for a bookcase carcase. The books I read give good instructions on how to do this but they assume that if you want to end up with a
3/4 in. thick carcase board you start with 4/4 boards and after glueing them together you pass it through a planer to get the final 3/4 thickness.I once made, just for practice, a wide board by this edge-glueing method and it worked except that the boards did not line up perfectly. I wanted the final board to be 3/4 in. thick and I started with 3/4 in. boards. I sanded the uneven areas and got it fairly level but it did reduce the thickness in some places. I'm sure that this slight mis-alignment is what the final planing takes care of. But I want to know if I could, with a little practice, start with boards of the final thickness, glue them together, and not have to do the planing.
Does anyone start with dressed 3/4 boards and glue them up to make a wider panel 3/4 thick that does not have to be passed through a planer? Or do I have to start with 4/4 stock and plane it after glue-up?
Thanks, Billy
