    I've never seen any precisely like that, but overall they look like pieces of R&L turret-mounted end-working tools, also see the roller backrests at the top of the page here. The similar bits I've...

    Oh, Hell no. For a bunch of reasons, chief among them the immense waste of time and the squandering of knurl tool life.

    There are several alternatives. First, it may be a lot less perfectly...

    I like the wheel guards, but think they only deal with the "accidently side- or back-step into it" issue. Anybody sticking a hand, wrench, or stick into the zone of high-speed pain might would be...

    I'm going to address the issue of the horizontal bearing surfaces only covering a small fraction of the "frontage" of the vertical bearing surfaces. If the original bearing surfaces protrude above...

    Down to a point, yes. The soak has to be long enough for internal temperature to equalize if you want to avoid banana-shaped parts on quench.

    If you're planning a shop experiment with molten salt baths, another possible technique is fluidized combustion beds. Briefly, fuel gas is piped into the bottom of a container of sand or other...

    If you use the angle grinder, try a flap disk instead of a hard wheel. It may be more controllable, and less prone to digging grooves.

    I'm pretty sure the engraving of the Hardinge compound is trying to show engine turning (jeweling). It looks a little like butterfly patterns due to the limitations of the engraving and/or photo...

    And he wants $1500 for it. Be a hard sell in most regions even if it still had all its parts!

    That weight for the Regal does not surprise me much. I have a 10-year old Chinese 16x40 of adequate construction, and it weighs slightly over 4000 pounds. I would be astonished if a classic iron...

    I would assume the lift-gate delivery truck comes with a palette jack. If you prepare a nice surface for the driver, he/she will probably be quite happy to move the palette as far as the nice...

    They are code words in the strictest sense of the term. Telegraph codes. Back in the day, you paid for telegraphs by the word. It was routine for manufacturers to give a one-word (usually five...

    It was my impression that Durabar didn't sell anything shorter than six foot sticks, with their regional distros acting as service centers to cut it down. If that's not the case, please update this...

    You could probably get 100 or 200 $ on eBay for it fairly quickly. When I need one, which is when I am making more than about 10 of the same part on my DSM-50, I improvise from a couple of tall pipe...

    Heard a report on the radio yesterday that Boeing was planning to cut about 10% of a 160,000 workforce. Some layoffs, some buyouts, most from the Seattle area plants.

    The 0.02mm/m vials are definitely sensitive. As practical matter, use a less sensitive level first to get things in the ballpark.
