Over the years my sinuses have become more and more sensitive to fine wood particles. I wear a dust mask now even with the dust collection and a filtration unit, every thing 5 microns. I solved for the most part the worst offender, the chop saw, by building a box almost completely around the saw and sticking a 4" hose from the collector into box. It throws a few shavings but seems to taken care of the really fine stuff. Something fixed in place like Tom's pvc pickup tube would work under my band saw table, another major source of fine particles.
It appears the only joint issues happen to be with the two legs holding the hoist and the wide stretchers between them. I re-clamped, checked for square and added two, pre-drilled screws through each leg and tenon. All tight again. No more up and down it until I get a couple of benches on either side to help anchor the side tables.
