    Or Grainger?

    I would add a solid state contactor that is rated for about twice the load your motor's rating. Then the pressure switch would last longer than you will.

    I am retired. But for what I would charge you to refurbish that one, you could buy 2, 3, or even 4 new ones.

    Either do it yourself or, as Ramsey said, toss it and buy a new one.

    "How can I easily set the power feed stops without resorting to trial and error?"

    Simple answer, you can not.

    More complicated answer would be to mount those switches with a micrometer...

    If this is a one-off or a two-see or three-see, I say go for it. With careful steps and clean out the chips after each pass.

    If this is a production situation and many parts must be cut, then...

    I will be watching this thread carefully. I need something myself. I have been thinking about a cart that holds three devices in rotating fashion and has either a bridge for sliding them or some kind...

    Boy, I just love these discussions about audio. In a 45+ year career as a TV engineer, audio was almost always more problematic than the video in any situation where I found myself. Almost everyone...

    Neither tubes nor transistors, on their own, are free of distortion. They both have non-linear characteristics. It is the circuits that they are employed in that either correct this distortion or, as...

    A bit more on the reason and a suggested board where you will be well received:

    As I understand it, this board was set up for working professional machinists. As such, their time is valuable and...

    Yup!

    I have worked in places where there were no others who I could really share my work related problems with. I was a ONO (one and only) in my job. I loved it when the internet came along where...

    There are a number of words that I would consider better, clearer when used in different situations.

    "Clock" or "clocking" is perhaps most used in the UK when referring to dial and dial test...

    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...

    Find an old, preferably telephoto, 35mm camera lens and take it apart. The focusing thread will be a two, three, or four start.

    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...

    He said it is a 25 HP. Not something I am going to pick up, but not overly large either.
