    I'm in one of those, but we also have a shared machine shop (manual mill, lathe, Prototrak bed mill, saws, etc), weld shop, wood shop, 3D printer, composites layup room, and oven. It's a great setup....

    Rather than getting a machine shop to do it, you might look at getting it done by a steel yard that has a drill spindle on their plasma table. I've done a fair number of plates like this where they...

    The other alternative, of course, is a stupidly accurate leadscrew. Moore's book "Foundations of Mechanical Accuracy" is a fascinating read and tells you everything you need to know to build a...

    We usually used Heidenhain LC glass scales, they are +-3um or +-5um, so not as good as the Renishaw. I think we used to hold drill countersink depth to a few tenths, but that was more of a...

    OT: Inland Marine insurance

    We do a few high dollar shipments a year. We fill up a flatbed with high dollar equipment. Inland marine insurance is up for renewal and I'm being quoted a minimum premium of $2500, so even though...

    Two others that might be worth looking at:

    Weiler. Very nice, very german, probably very expensive

    Southwestern Industries/ProtoTrak. You can use these as either a manual lathe or as a CNC with...

    I don't own one, but from what I hear on the forum, Babin does very nice Hardinge rebuilds and builds an HLV-H clone

    You have accused a manufacturer of not following a standard, and, from the sound of it, rejected a machine, because they didn't follow your preferred rule of thumb of 10:1 for Test Accuracy Ratio...

    Except the accuracy isn't 5.1um. You actually have to calculate the measurement uncertainty, not just add numbers together.

    Take a look at JCGM 106:2012 Evaluation of measurement data – The role...

    The rules for salaried exempt* employees are weird and unintuitive. As I understand them, they can't dock your pay for less than full-day absences. They can, however, make you use your PTO, in which...

    As others have pointed out, you aren't following a standard, but rather a rule-of-thumb. The actual standards are, I think, the ISO guides to the expression of uncertainty in measurement and, maybe,...

    If you have a crane, you lay the sheet out on the floor, place foam and, if required, plywood where the feet will land, and then crane the machine on to the sheet. Then you just wrap it up like a...

    1) LPS-3 is definitely the way to go. As suggested earlier, get a hand pump sprayer and use that to apply it. Make sure you LPS every piece of steel that isn't painted (including under the way...

    I would think that any of the standard PVD coatings would work if you coat after casting. For coating before casting, CrN or AlTiN have 700C service temperatures. I don't know how they'd handle...

    Can you expand a little more on what you're doing now with Solidworks? I've done it the other way, where Solidworks pulls dimensions from an excel file, but I've never seen it initiated from the...

    Unless I'm completely mistaken, the 1/4-20 threads into the edge of the 3/16 plate isn't necessarily a problem if this is machined after welding. The tapped holes appear to be for magnets. They are...

    You need to be licensed in every state you want to be able to stamp stuff in. So I, for example, have two PE licenses, one in Washington and one in Maine. My Washington stamp has my Washington...

    I hadn't thought of wet stamping, signing, and scanning. That might be the easiest option.

    Let me clarify. I have the wet stamp. I'm looking to put the stamp into Solidworks as a sketch block so I don't have to wet stamp and sign a gazillion pages. Unfortunately, Washington won't let you...

    OT: Washington PE Stamp

    Does anyone have an editable Washington PE stamp sketch block? I'm actually going to have to stamp something this year.

    Thanks,

    You might also check with suppliers of plastic welding wire. I imagine they have certs for everything. 1/32" wire is going to be a tiny bit undersize for you though.

    If all you need is a certificate of analysis, it might be worth looking at buying what you need and sending samples off for analysis. I know a lab that could do it easily, but I don't know what it...
