    Actually, the Hardinge TT releasing tap head (for turret lathes with reversing spindles) would not be a hard shop project.

    If you had a source for an appropriately sized planetary gear set, you...

    Socket head shoulder screws are frequently used to retain the stripper plates in punch press die sets, which is why they are often called stripper bolts. Obviously, they can be used for lots of...

    ??? I would expect off-the-shelf O1 bar stock to be annealed, not quenched. If that's what you're buying, complain to your vendor. Until they can fix the supply problem, find a local heat-treater...

    I wasn't familiar with that abbreviation, but Google reveals that LO can be used for external NO GO, while HI can be used for internal NO GO. See the discussion here.

    EPAIII, this must be the month for this particular question. I think there are four, maybe five, threads on the topic/question in the last few weeks.
    All those questions answered here among other...

    If I need something right away, or just a half-dozen, I visit my local Ace Hardware, which is actually a hardware store, not a mini-Target. They frequently have boxes of 100, tucked away behind the...

    I don't know how well it would work for steels, but the local high school robot team shop uses a 2" or 2.5" ShearHog on a Jet Bridgeport clone to face off aluminum, and it's a favorite tool.

    I've got a 7.5HP 16" swing lathe, weight about 4400 pounds, and it will part 3.5" or 4", but it's working at it, and it requires noticeable cross feed thrust to keep a chip forming. moonlight...

    The biggest convenience is that they are ground for specific thread forms (and usually pitches, unless you buy the partial profile ones). Most of them have chipbreakers which work. Those are really...

    Parting can be even more sensitive to tool being at centerheight than turning. Double check that, and make sure the tool has a keen edge.

    Do you cut off with power cross feed? (I'm assuming a...

    Wire sawing, yes. Garroting, no, at least with actual wire rather than something out of a science fantasy. It is a common practice to pull stumps with a choke loop around the trunk. Exceeds the...

    I'd strongly encourage you not to take detector power directly from the e-stop circuit. If the e-stop series is connected on one end to a 24V source, then run a separate wire from the 24V source to...

    Just to expand on that slightly. Use the NC contacts of the relay (two wires) in the emergency stop series. Use the flame detector output to drive the coil of the relay (two wires). The flame...

    rabtrfld, the larger sizes of laydown threading toolholders have shims to control helix angle. On the smaller ones,
    you just learn to live with the compromise of whatever helix is built into the...

    At that price, I am strongly tempted to buy it just to get a spare gearmotor for my existing Nichols!

    Two comments: 1) If it won't interfere with your working headroom, you can use a wire rope between the ends of a flattish arc to stiffen it up and resist the spreading forces. In a truss, this...

    Standridge does have a complete price list online, which you can download without providing their sales and marketing guys any data. It's just separate from their web catalog.

    From your description, I suspect the start/run capacitor needs to be replaced! Fortunately, these are a very broad tolerance item, so any start/run capacitor with the same-or-better voltage rating...

    Potentially: price, color, rigidity, other mechanical limitations. I'd encourage you to glance at the "star diagram" near the bottom of this page, where one manufacturer compares six physical...

    It totally depends on what resin you use. Some resins are brittle, especially after exposure to full sunlight or other UV source.

    Yes, I meant die spotting or marking compound (Canode, or Prussian Blue in grease), not layout die or colored shellac. Dykem makes both hi-spot blue and layout blue, so the brand name alone won't...

    You'll have to compare the specific models you're interested in, but in general the SLA resin printers have a much higher resolution than the FDM thermoplastic printers in the same price range. I...

    Triangular threading inserts, with one cutting position per corner.
    Because the triangle is oriented in a horizontal plane, as if it were lying down on a table top. There are also triangular...
