    Xometry. Once your job is complete, you download and print a UPS or FedEx shipping label.

    1/32" most of the time if the soft jaws are wider than the part. I have a nice set of 1/32" parallels for this purpose. I have never found chips getting between the jaws to be a problem, since the...

    Why do you say that? It depends on the price per part. If it's priced right, it's a money-maker regardless of what tech you use. I made ~14,000 thingys a few years ago -- 1 lathe op, 2 mill ops, and...

    You're only looking at ~500# of material at net size to make ~10,000 of these. Is that enough to interest an extrusion outfit? And how much does a 1-off extrusion die cost? Granted this one would be...

    Generally, bog-standard 6061-T6xxx is extruded. There is cold-rolled 6061, but it comes at a premium to extruded.

    Or, are you asking specifically about 6061-T6?

    Regards.

    Pretty slow for me. Scraped together enough oddball work to have a decent May. Maybe the company that I did some work for awhile ago, that makes non-lethal launchers, will be back in touch ;).

    About half of my work is Boeing-related, and that all dropped way off since a few months ago.

    On the plus side, the gardens and yard have never looked better :-).

    I know, but I'm giving room for a more generous explanation ;). Might not be one.
