Cool - I like that but am afraid of the weight of my new dust boot setup to clear the 4.2" spindle and hookup to a 4" pipe. I could make that holder on top for the hose out of hdpe maybe… Always cool ideas to see around what people come up with! Also on the XXL table, I was forever bothered by not only gaps, but arching in the straps so I actually mounted similar to grumpa with taking out void spaces and shimmed like crazy down to sheets of paper to try and level the alum extrusion surface I put on it. From there bolting my bench / table to the wall had made it magnitudes more rigid. I may be actually moving the outside wall a bit when jogging my XXL since it’s soooo jerky start / stopping (plus the added weight/inertia of course). Hope it’s all running well!
