I seek your advice.
I’m in the process of making several speaker cabinets out of 1.5” oak. I use the vertical gluing clamp made by Plano and love it. The last pieces I glued up were three tops for the cabinets measuring roughly 16” x 16” each. I had applied the glue and clamped the first two. I had applied the glue and placed the third piece in the clamp, closed the clamp but hadn’t tightened it when I got interrupted. I wiped the glue squeeze out off all three tops and left for dinner. This morning I removed each piece. Often, I loosen the clamps on all the clamps first, and then remove the pieces one at a time, but not always.
When I got to the thire piece, the clamp was loosened, but I honestly can’t remember loosening it, so I’m worried that I never tightened the clamp on that piece in the first place. I think I did, but I’m not sure.
Now, when I examined the piece, it was perfect. I did a quick 80 grit sanding and there were no gaps between the edges, and the boards were perfectly flush. That is, when I ran my hand accross the grain, it was perfectly smooth. It seems highly unlikely that I could have lucked out so much that the piece would be perfect if I hadn’t tightened the clamps. But, I still worry….
Thus my two questions:
If the clamp had not been tightened, and the only pressure on the boards was their own weight, am I going to end up with weak joints?
Should I make another piece to replace the one that might not have been clamped?
Thanks so much for your advice.
