    That looks real good. Nice job.

    I recently did something similar but without the casters. I move my mill with a pallet jack that fits between the feet. It’s not ideal. It’s not easy getting the...

    Agree, but would like to respectfully quibble a tiny bit. The nuts may not be split. Mine were not. That change occurred at some point in time after 1967 when my mill was made. So adjusting out...

    I don’t think backlash is a good indicator of wear on the ways. It indicates screw/nut wear and can often be adjusted out.

    I would go with flaking evidence. If the knee ways were worn smooth, that...

    I suspect machinery dealers can be like used car dealers. They have expertise in hiding flaws that can really come back and bite you, where normal sellers don’t.

    That said, there are probably...

    I think aluminum tee nuts are a really great idea. Could also use brass. I think tee-nuts are excellent projects, easy, yet challenging to get just right.

    FWIW, I like the flats on the studs...

    You have the right attitude my friend!! I think $100 might be a little steep for a 12X18. Is it a Starrett Crystal Pink? I'm partial to them because they are quartz and wear VERY slowly so they...

    We don’t know what you already have. You really will need everything on my list, yes even the surface plate.

    Step one, cleaning and oiling the machine. This can be as invasive or non-invasive as...

    Yeah, it’s a lot and these are just the basics. You don’t need everything to turn the machine on and make chips, but when you start making even basic parts, you likely will need most of that stuff....

    Your boss is right. You don’t need any of those squares. Get a decent straight edge and tape it to a flat table. Place a framing square against the straight edge, draw a line then flip it over and...

    I think you are right. Engineering means .0002”/10”. If the part was 30” and you wanted .0002” overall, you would have left it at that.

    Only wrinkle is Rule 1. If there is a size tolerance, form...

    You know there is no AS-0 gage block std in the ASME spec, right? So do we believe they got the grade wrong, but everything else is spot on? Come on guys.

    How naive must we be to even discuss NIST traceable products from China? This is a joke.

    And I don’t think temperature changes permanently effect gage blocks. I’d buy used. If you are worried...

    What? Can you explain this a bit more? You are saying the table was flat but rose .005” at the ends due to what again? You are thinking the ways were worn .005”?

    42” table is closer to 300lbs. Just in case you feel the need to pull it. I was able to pick it up off a Rubbermaid cart and carry it like a baby. I never thought of myself as strong and I’m 57. It’s...
