    If you find any, astonish us all and post the source here. Go&Go tools were reasonably common, but I don't think there was ever a second source for their proprietary cutters. And the dominance of...

    A 50" overall length is really, really pushing it for any decent machine. While there are probably a number of obscure, unobtainable machines of decent quality that fit that constraint, about the...

    As just one teeny tiny example, I have long felt that the engineers and industrial designers (two rather different categories) who design the thumbscrews that secure cable plugs to receptacles (e.g.,...

    In addition to counterbores, check out Forstner drill bits. (A type, not a brand.) They are like what you show, but without the pilot drill.

    Brochure linked from that webpage says:

    That doesn't answer the question of who makes it, of course. Although the brochure also claims "100% MADE IN GERMANY".

    I've done just this on a floor-standing arbor press frame that was far too large to submerge in any bucket or improvised basin. Made a dam from semi-rigid plastic sheet and plumber's putty to...

    Ask your bud? If I had to guess, I'd guess a center lap, to clean up worn or possibly boogered-up centers on a part.

    Ditto on the recommendation for Severance chamfering tools.

    Make a fixure with a flip-out-of-the-way part stop, a part clamp, and a drill spindle with a depth stop. Retract the spindle, put the...

    I run the Mobil products, which are readily available, but if you prefer another brand, any good quality ISO 68 viscosity way oil will substitute for the Vactra#2, and any good quality ISO 10...

    I think he's talking about an edge finder with 1/2" shank and 1/2" endcap.

    I am also having a hard time visualizing how this annulus ("washer") was cut into segments. I am guessing that the thing...

    They look like magnetic transfer blocks for use with a magnetic chuck.
    The stripes of ferrous metal "conduct" the magnetic field lines (if
    you will accept a very imperfect analogy), so you can use...

    Definitely not. You would need the coordinates and weights of all 14 control points to define the untrimmed surface, and you'd need the full detail of the trim curves to know where to stop.
