    There's a metal optics shield/edge guide on the nozzle, I suspect (hope!) that there's a continuity or inductance sensor there to ensure contact with the work and that automatically cuts the beam if...

    I get the sense that this might be a good material to use "dubbed" (small neutral rake flat) cutting edges on HSS tooling for satisfactory machining.

    Without trying a sample myself this is just...

    With an internal fitted disk to support the ring, you could lap to a precision thickness using a single or double-sided lapping machine. I'd consider this method if you "have to go there". Might...

    Nah, he wants the levels to check twist of the bed, a fine use for 199's. Gross level of the machine, I agree - normal levels are OK.

    On that plate - presumably it's steel? For the weight, it's...

    I have an optical polygon (eight sides), I'm afraid I'll not be getting it certed at that price (although it's more reasonable than the rotary table pricing - could that be a...

    I don't have immediate references, but I've read that the Vactra formula had too much paraffin solids in it that could precipitate out and clog lines and filters. I've noticed in the past solids...

    Looking forward to seeing the new design of pull stud. Will it be around the same cost as the J&M variant, or more? Will it have a pilot diameter, or is that feature protected?
