    One interesting thing I saw on a sheet metal bender was where the hold-down fingers had been replaced by a large electromagnet. It attracted itself to the lower platen, and seemed to work on both...

    Just how much runout do you have? If it's *lots*, then I think Brian might have it - either a jaw in the wrong slot, or a jaw inserted one revolution of the scroll too late.

    Take them all out,...

    Probably my Union tool & cutter grinder. Lovely machine, but it seems quicker ordering a new end mill from Ebay.

    What's inside the cabinet? Is there a plate that the 4 bolts on the bottom of the risers thread into, or is it just 4 nuts & washers? The bed is a whole lot more rigid than the cabinet, and jacking...

    If you have a VFD, rather than using it as an on-off switch, how about fitting a pressure sensor and controlling the speed of the motor? So when you have a high offtake, the motor speeds up and more...

    As others have said, the nut & backplates have right hand threads, so you're tightening it, not slackening it off.

    The taper should be really tight by now :)

    We're looking at replacing one post here, 4"x 4"? Use azobe. Set it in concrete, or rocks, or sand, or microbe-infested mud. It doesn't matter. No need to treat it - it'll never rot, ever. Until...

    The material is indeed galvanized; they're standard scaffold pipes.

    If the poles were cantilevered from the wall, I'd indeed set them at an angle. In this case, however, they're effectively pin...

    My first thought was that someone had been a little over-enthusiastic with an angle grinder. I pity the poor bugger who they finally pin it on.

    I wonder if he had insurance?
