    Not a New Machine Day, but these are new shop tool carts by Seville Classics. Butcher-block tops, ball-bearing drawers, nice small footprint—not heavy built like a Kennedy but plenty sturdy enough to...

    The Royals are hardened. If you're going to make one, make the one with the partoff blade holder. Doesn't waste a turret station. We have four, worth every cent.

    "Bringing back" hard-tooled manufacturing like ball bearings, lathe chucks, aftermarket crankshafts and so forth is a misleading expression. The facilities where that stuff was made were idled,...

    Wasn't he the guy running the aerospace shop somewhere in Arkansas, using custom software to route his $20M annual throughput? How does he need to ask an internet forum how to find a machinery hauler?

    I would add that high-quality cermets like Kyocera has produced for 40 years are in a different category of chip formation entirely. It would take quite some fancy camera to show that. Turning 1" Ø...

    I just reread adh2000's post about the dies and I don't know where I got the impression he had to make multiple die pairs. Duh. So probably they were rotary swaging the parts, but they would have had...

    The sand contains voids which compress and spoil your bend. To cold-bend it, try a low-melting-point alloy and thread caps into the ends. To bend it hot freehand, don't heat the outside of the bend,...

    The "slipping blade" as a safety measure works on a hand-cranked Bridgeport but not on a powered cut. If you have arbor spacers with key clearance, use a Dremel to grind a keyway in the saw and let...
