    If it responds differently depending on where you place it, doesn't that indicate variations in your reference surface? That is, your flat isn't reliably flat.

    If you do any form grinding that's a wonderful tool and a steal at that price.

    The best thing I can think of relating to the salesman's recommendation is that it gives me an idea for a new screen name. Max Regrind. Kinda like that.

    I've got ball end mills that I use on a mill. Not a lot, but if you need it, there's no good substitute. I just recently used one on a straightedge casting to establish a shallow depression...

    There's an old binary sort for how to manage what to really worry about.

    First of all, you're either healthy or sick.

    If you're healthy you've got nothing to worry about but if you're sick...

    No help here but a tickle of nostalgia.

    We bought our first NC machine in the 80's, a Mitsubishi wire for the toolroom and the Elan system to program and punch tape for it. At that time the...

    So he's proposing to help individuals who don't really understand finance get placed in responsible positions by cheating? I'm not sure that's the kind of help we need.

    In fact, could he and his...

    The traditional way would have been to form the roll, mostly closed and then finish in assembly. It doesn't have to be able to rotate. If you want to know how a roll might be formed I've got...

    I haven't separated this from the strap because it's riveted, but you can see the design. There's a tubular roller just visible to reduce chafing on the strap, and the upper portion where the strap...

    From my look at one, or a similar tool, it's a cutting tool to re-establish circularity if the crank pin has been worn oval. The crank is mounted in the lathe on the crank centerline so the crank...

    Heck., put some straps on a Chore Girl copper scrubber and there you go. Sounds like that should work to me.

    Suggesting a jump over to a hobby machinist site is like a fart in church on this forum. And knowing that you also have a thread started on the...

    No criticism but at least a clarification. You've proved that the two scales read the same. They could both be accurate or they could both have exactly the same error. To prove that one is...
