    You could call the number and ask if you can use your own material. Then bid accordingly.

    My Dad was a salesman in the 60s, and he had a "customer" that kept calling him for bids. After 6 bids...

    Yeah, there's the obvious. But if the part has to be certified by Xometry, or if additional operations are needed, Xometry may want to ensure compliance/documentation/good quality material.

    Still,...

    You got me wondering if my eyes are going, Cal. I'm seeing tempering temperature on the lower left graph going down to 400° F. Depending upon the original temper, 650°F could drop the tensile 20%...

    Good heavens, we've had another Covid-related-thread outbreak. There are still people who think that their post is gonna convince diametrically-opposed opinions.

    But wait! There's a related...

    Very pleased to help. A pic of the renovated table woudl be cool.

    This actually brings up a question. In my table, there's a hole in the base, and it leads from the oil sump to the top of the...

    Trump delayed quarantine!
    Trump Implemented Quarantine and Flight Ban and Was Criticized as Being Premature!

    If the owner was a slob like me, probably a lubricating bronze. Given the OP's stated good lubrication discipline, though, wouldn't a bearing bronze be indicated? C93700?
  8. If the half nut is subject to a lot of high...

    If the half nut is subject to a lot of high stresses (and not just a high percentage duty cycle of moderate to low stress) I'd be leery (wary, skeptical) about acetal. I used to work in the DuPont...

    And left hand, too!

    The point you make is profound: Making a half-nut is a LOT easier than making a super precise lead screw. So perhaps the concern should not be what nut material resists wear,...

    I found this info useful. IMHO, plaster is a little bit easier to replace I think - hard to scrape broken glass and cured RTV out of a small hole if the vial breaks again. BTW, in a nonproduction...

    I think that the pawl is similar to the one in a Dake 3. I've attached a pic stolen from another PM thread of the Model 3 Pawl. You should be able to scale this to your machine I think. Picture 2...

    David,
    Your note prompted a thought. If we are to take the OP at his word, and I do, he's a Journeyman Tool and Diemaker. That's not a qualification that you get off the back of a box of corn...

    Comes in 18 or 36 inches lengths. The 3/32 x 6 x 18 in O-1 is $126 direct from Starrett. If you cut with a 1/16" kerf you'd have enough for the OP's desired set. But I think you'd probably want to...

    Despite the OP's protests, what he's asking for for $150 is nuts. A set of Suburban parallels (and not even the complete set the OP wants) is over 800 bucks. Just buying flat ground stock enough...

    Same as in bottom-of-head to end of threaded part, or same as in top-of-head to end of threaded part? I think that unless the screw heads are really precise, if its bottom of head to end of thread,...

    I live about 20 miles away from a steel mill that makes P20 steel. Guarantees no voids (that's another criterion for Marcus's list).

    It seems to me that in the "one shouldn't do this" vs "why the hell not?" argument there are some missing topics, like actual science (not speculation), engineering, and legal requirements.

    I...

    After we figure out Covid, can I come over? I'll do my part and twist the peppermill. Oh, and I'll make the Vieux Carre's.

    Similar for me. I bought the mechanism and the Claro Walnut blank and turned it on my Delta 11 inch wood lathe (it's from the 50s or 40s, weighs 500 lbs, and has a tool holder for light metal work: a...

    Yes, but connecting the source to the fork lift is really uncomfortable. The barbed fitting in the middle of the seat is ok when you're stationary, but sudden starts and stops are killer....

    Nah, just order a "Scholla" or "Alster Bier", or "Radler". Half Pils, and half .... 7 Up (or other lemon-lime soda). You can drink those things pretty much all day and not get too hammered.

    But the USPS also had very high rates. So not sure what's going on.

    But back to your premise. Higher shipping for the consumer or small businesses is really disastrous for a free economy. Think...
