I crank down pretty tight, with F-style clamps I go to about 80% of the tightest I could possibly do with my bare hands, I’d say. With clamps with a pin or crank handle, which gives you a lever arm, I guess I go until the bar starts to flex.
But this seems like a great experiment since TungOil just closes the joint – I’d like to do 3 glue-ups on identically jointed boards and do a fracture test on all 3. Varying clamp pressure or number of clamps for each. Maybe someone else would like to try? To cold for gluing in my shop this week.
