    Well, that's the general trajectory of higher education. As you advance from a Bachelors degree to the Masters you learn more and more about less and less. Finally with your PhD you know everything...

    They're designed to be able to control radial clearance, just as your situation requires. Picture a sleeve bearing that's tapered on the OD. It fits in the housing (headstock of whatever) which has...

    Another interesting situation

    So years back I worked in a shop that was represented by a union in a right-to-work state. And I was curious how the politics and machinations worked. To get a little more insight I'd come across a...

    I have both a degree and shop experience, not necessarily in that order.

    So I'd had four years of college but changed majors so it didn't add up to a degree requirement and I felt like it wasn't...

    Color me jealous. Beautiful machine there and I hope you'll have a good time with it.

    I would read the instructions to mean that the anvils, if fully closed, are .450 thick.

    It's harder if the mic isn't digital, but if you followed the instructions, zero set with the 1" standard...

    I bought a new charger a couple years ago to replace a much older one that sank in a flood. The technology in this one is new to me as electronics have taken over functions.

    So I had a battery...

    Not entirely true. He's pushing the idea that he's the one to make a huge splash in gear production, one that no one else has done. The reward is lots of attaboys on the forums.

    If you're talking about something that just holds a tap vertically, yes I've seen plans for more than one.

    If you're talking about reversing heads, then no, I've never seen plans for a DIY. ...

    Saying that you need to center a piece of round stock suggests you're working on the end of round stock sticking up.

    So, if you just clamp your stock in the vise where it's convenient, get the X-Y...

    It would be the one with the "exception" and "normal" label.

    Boy, that's a tough one. You've got to admire the technology and capabilities of a rotary head mill. And if you have one in your shop and use it often enough it would be great. But if you use the...

    My hand held calculator will do exactly the same thing and doesn't take up much space in the shop. It still won't tell me which blocks to pull to make up that gage block stack, though.

    He shoulda mentioned it's missing the tailstock. And that you can't get there with an ordinary forklift. Bring an offroad crane that can reach in and pick it out from a safe distance.

    Traditionally they were slightly concave, produced by grinding sideways across the wheel, so stropping on the stone produced small flats and sharp edges.
