    OT: SpaceX Starship/Booster test flight 04/20/23

    Just watched the SpaceX stream, and damn, what an impressive beast that rocket is. It got off the pad with minimal damage, but failed the separation, so after a few flips they sent the destruct signal. Worth checking out replays if space interests you. I saw at least one of the Booster engines...

    Lots of spam recently, time for a delay between registering and posting?

    Hi all y'all, As per title, why not have a one-day delay between registering and permission to post? It's gotten a little much the last few days with spam-spam-spam, and rather that wasting people's time reporting and clearing it out, why not have a tiny little barrier to make it a touch more...

    Explosion with serious injuries at Ohio metals plant

    Sad news, but hopefully no fatalities: https://www.cnn.com/2023/02/20/us/oakwood-ohio-plant-explosion-fire/index.html It's the I. Schumann & Co. building, looks like a "red metals" producer, with alloy mix and recyling capabilities. I suspect either a water/hot metals event, or heating...

    OT-ish - A battleship's machine shop

    There's a YT creator I follow called Drachinifel who's quite knowledgeable about pre-Cold War Navy ships from around the world. He's done a number of videos on US ships, from monitors to destroyers to aircraft carriers. One he recently released is on the "fast battleship" USS North Carolina, and...

    Replacing Haas VF gearbox oil pump coupling on older VMC's?

    Hi all you Haasheads, My 2001 VF-5 threw the code for failure of gearbox oil cooling/circulation last night, and while it could be low oil, it's more likely a failed polymer coupling between the oil pump and motor. I haven't checked yet (didn't want to climb on the machine while tired), but...

    Add-on method of chip control when drilling?

    Hi all, At 1:04 in on this video: Toshiba Machine BTD-110H.R16 - YouTube There's a (dry run) drilling operation, and what interested me is there's a ring with prongs added to the drill bit, sort of like the countersinks that can be added to woodworker's bits. But in this case, my only guess...

    Impressive laser-assisted-machining optics lathe

    Hi all, Not sure if anyone's posted this video here before, but check out this very capable laser-lathe: Micro LAM Overview 2016 - YouTube Not sure the wavelength they're using (the HeNe beam shown seems to be just for alignment) or the wattage, but they're passing it through a single-crystal...

    Test, will delete shortly

    Posting blank text? It seems an Ebay link caused the issue, was able to post when the link was removed. No delete option in edit? WTF?? [Oh well, we're stuck with this unless a mod can do it in...]

    Haas customer communications team had a misfire...

    Like many of us (unless you've got them blocked), I get emails from Haas advertising one or another of their products - from VMCs to rotary tables to the relatively recent addition of tooling. Well, someone got their address database a bit mixed up, because I just got an email for the new-style...

    Major US retailer (who sold US products) bites the dust

    Goodbye to Sears Auto Centers | Modern Tire Dealer Sears Auto Centers, a "surviving" member of the old Sears Roebuck, has passed the checkered flag and is joining the ranks of the re-tired. Dead tired? I'm not sure I'm in the mood for puns... [Shakes fist] Damn you, Amazon!

    Livestream of the JWST starting at 6am EST: James Webb Space Telescope Launch — Official NASA Broadcast - YouTube. Launch is scheduled for 7:20am EST (12:20 UTC), but there's likely to be slip or possibly rescheduling. It's not OT as it's got some of the most complex, large, and EXPENSIVE...

    Cost of not disconnecting a scrap vehicle's battery...

    NTSB: Used Vehicle Battery Caused Weeklong Cargo Ship Fire | IMPO These cars were due to go overseas to be scrapped, but a small error in securing a battery led to a bit of a problem. Now the ship is scrap too... Moral of the story: It's all Tesla's fault! [Ok, not this time]. Be careful...

    Fairer taxes, less stressed small businesses (and workers?)

    https://www.washingtonpost.com/us-policy/2021/10/30/biden-g20-global-minimum-tax/ It's about F'ing time! Part of why it seems we're at each others throats every day is the general stress over the decline of living standards of the "average" blue collar worker. That's in part due to the...

    Bad news for Aluminum users (hopefully only short-term)

    Aluminum prices hit decade high as coup threatens supplies from Guinea - CNN The coup may bump prices up, but generals "generally" like to get the economic side of the country back in gear asap, if for no other reason than to up the looting potential. So my fully-uninformed guess is that this...

    LIVE: Starship SN15 Flight Test - YouTube Hey, there's a lot of manufacturing that goes on when making a Starship, right? They're more than eight hours into the stream at time of writing, these test flights usually aren't exactly on time. If there's a hold or scrub I'll update. [Just heard...
