    OK, that eliminates ONE possibility. Do we have to ask about all other possibilities, one by one?

    That is one thing that it is not. But, for Pete's sake, WHAT IS IT?

    Is this a purely cosmetic...

    Nice looking piece of old hardware. Is it a 6" or larger?

    There are two sets of keyways on the bottom so it could have been keyed for two mounting orientations. And the combination of the round...

    Opticians/lens makers. And yes, aluminum has been used for mirrors.

    Telescope makers.

    Aluminum can be polished using ordinary, abrasive and polishing compounds. But if it needs to have...

    I have one from Luminar and it is great. I believe they make two different models for different mills. So be sure it will fit your mill or it can be returned if not.

    If you want buyer protection, always, Always, ALWAYS use a CREDIT card for the purchase. Not a debit card, a CREDIT card.

    And if you use PayPal, fund the purchase with a CREDIT card. That option...

    And just HOW do you cut sheet metal without leaving a sharp edge or burr on at least one side?

    A torch, perhaps?

    When mounting a sliding scale to a machine, the first thing that I think about is the alignment between the scale and the reader head that slides on it. And any amount of clearance, IF ANY, that...

    Since it is a second hand tool, the first thing I would, before any epoxy is added, would be to go over the table surface to get rid of any burrs that are there now. The file idea is OK, but be aware...

    My thoughts on doing this in the lathe.

    1. If you want an accurately sized and ROUND hole, use a reamer for the final step. Use one with a long shank so it can "find" it's own center in the...

    As others have said, 1/4-16 gives you exactly 100%, calculating from your 80% and 1/4-20 numbers. But that is an EXACT number, not an "about" number which may wind up being on the shy side of what...

    I have my Starrett, 24" Vernier so that is probably good to +/-0.002" to that point. I have found that it sits nicely on top of my 2-4-6 blocks so it can be extended another 12" for 36" in all. Since...

    Well no one can blame you on that. At the price of US made bits, you should get proper packaging.

    You might try McMaster. They do not specify brands or country of manufacture, but I have not been...

    I have two height gauges and I find them quite useful.

    1. The obvious use is to scribe layout lines on a part. For this you will need the scribes. These are usually Z shaped so that they can be...

    There are so many motors and motor manufacturers out there that the best you can say is some are better than others.

    So, yes, check the specs for your particular motor. A 25 HP should have a spec...

    First you do not mention the alloy, you just say steel. Some steels machine like a dream and others are almost impossible to get better than your photos with a milling cutter.

    YES!

    I would not even try it. Mist, drip, brush on, or flood; just forget it.

    Personally I prefer oil based coolants for the lubricant effect, but I do understand the need for cooling in many...

    Your complaints with UPS make me wonder. Did you report the damage? And did you demand replacements from the supplier? I don't care what a supplier or the shipper that they choose says, when you...

    And yes, it is Paul. Not hiding anything: that's what I go by, my middle name. Perhaps I should incorporate it in my tag line. I picked the user name many years ago...

    Well, good luck with it. And remember the purpose for leveling a lathe is to have it turn proper cylinders. The actual level is not the end purpose AND it is not even the last step in setting a lathe...

    Assuming that this is a serious question, it is far, far too vague to obtain any decent answer.

    "machine too equipment" Another assumption is needed here: that probably was supposed to be...
