My dust collection system is almost finished and most of the stationary machines have been moved in place but I'm not satisfied with the results. It seems the shop arrangement is a constantly evolving process. My latest thought was to move some operations and machines upstairs onto a mezzanine. Heavy equipment would be impossible but I'm thinking the seldom used scroll saw and 2nd router table would be good candidates. If that ends up being a good idea I may keep the Powermatic dust collector now up for sale. Thoughts? Anyone else faced with the sickness of constantly rearranging their shop?
