    Turning 316L breaking inserts

    The operator makes it sound like he's been over that bridge a few times but if given the chance to talk to the tool supplier myself, I will certainly do so. That decision was made well above my pay grade and project scope.

    Ballistic .50 cal

    Kevlar is still used for pistol rated armor (2A & 3A) but against high velocity, pointed rounds you have to use steel, ceramic, or new to the market is UHMW. It would take a lot of kevlar to stop 5.56/5.45/7.62, hitting it with an AP 50 BMG would be laughable.

    Ballistic .50 cal

    I think a theoretical number is possible to calculate, but in reality you will have some not quite make it through and some will likely still be going several hundred feet per second. So, not really "accurate" in my estimation.

    Stacking an object

    If they are infinitely rigid, or made of something that effectively doesn't compress like concrete blocks, they will be much easier to stack. You get a stack of boxes that weigh 50lb each, you get 6 high and all is well, then someone comes by and bumps the bottom one putting a dent in it and...

    Any New Orleans Engineers here?

    I have a relative down there that used to tell me stories of her "adventures". Then she tried to get me to come down during Mardi Gras to experience it myself. After hearing the stories.....I'll pass.

    Turning 316L breaking inserts

    1st end op uses a hydraulic 4-jaw to clamp onto the rough OD, some parts use soft jaws cut to OD but I don't think that happens very often. Part ID gets bored in 1st end op so ID collets are used on 2nd end.

    Turning 316L breaking inserts

    Ed, as you and MFG pointed out, we may need to try deeper cuts. I know the operator has tried going deeper than .050" but not on any sort of consistent basis. Will discuss it further. Yes. We looked into 2101 a bit per your advice. It will take some investigation to see if we can get that...

    What do all the useless engineering graduates do for work?

    It wasn't one post, it was several posts over the course of several days if not weeks. We all have bad days, but you still need to hold yourself together as an adult. I've seen blue collar guys get away with stuff like that, but for someone who is supposed to be a professional, those would be...

    Turning 316L breaking inserts

    We have machined stainless parts forever but historically our primary material was brass. People above me have decided that we are switching to 316L as our primary material. Over the past few years, issues with the machineability of the 316L have become more frequent and now that it is our go to...

    White liquor and steel 316

    316 is generally considered to be an upgrade, we use it in contact with many various substances. I would not expect any issues.

    Follow Up

    So, I will go the opposite direction as Brian. In the street racing/light duty scene he may be correct so I'm not calling him wrong per say, but in the offroad world you want limiting straps to do all of the work, not the shocks. Of course in off road set ups, you are often talking about a solid...

    Omniscient Elon Musk seez....

    Admitting my mistake and making a correction is “digging myself deeper into the hole”, got it. I am not loud-mouthing in any way shape or form about these companies. I haven't made any sort of speculative claims on Musk's companies on any of my social media platforms, as I, nor do you or...

    Omniscient Elon Musk seez....

    Small inaccuracy made off the top of my head, edited for your reading pleasure. My point remains. I would expect nothing less.

    Omniscient Elon Musk seez....

    Is any part of this an actual technical, engineering minded, intelligently thought out discussion or just a bunch of borderline incoherent political schizo-ranting? When Columbus sailed across the Atlantic, people thought he was crazy. When the Wright Brothers said they would fly, people...

    Aerospace Engineering Experience

    Lol, this is pretty accurate. I designed some steel racks and I threw together some basic calculations for the load rating. Gave it to a coworker to look over and he said that we needed to consult our structural guy, as the C-channels I used were set such that the center web was vertical, so...
