I'm wondering if I can use vacuum clamping to glue up table legs. I'd
like to laminate 3 pieces of hard maple that are ~1x3x36" and I need
to make up around 50 of them. Provided the material is flat and well
surfaced, will atmospheric pressure provide sufficient clamping
pressure for a nearly invisible glue line? Or am I better off
throwing them in the clamp rack? Probably the latter, I'd guess, but
I'm not totally confident of my understanding of atmospheric
pressure. It's 1774 per square foot, right? I can easily get more
than that with bar clamps. Maybe I answered my own question.
