Husband, father, machinist, and amateur tuba player. Rockets are cool and nuclear power is goated. My political opinions may be inconsistent and crazy.

@SutterlinDan @__el__toro__ I don't think I've ever seen a three flute tool make a three lobed shape. Usually with the tool bouncing around you get at least one more lobe than the number of flutes on the tool.

@pencilforge @obiwormkenobi I've heard both Libry and Libary, actually.

@takeshi7 @MakeAugusta I wish I could ask. To me that assembly would be a battery, I guess.

[Seth Legare 🚀⚛️📯 @setbri]

@Local_Dog_Awoos @RichieBillie10 @juiceetin You mean USB type A or type B. USB 2.0 is a protocol and a decent amount of type C stuff is 2.0

@pintleinjector What about Ariane 6, GSLV, H3, and the Chinese ones?

[Seth Legare 🚀⚛️📯 @setbri]

@LauraPowellEsq @WMcluskey Respectfully I don't think you understand. I once ran a half mile in shorts, a t-shirt, and flip-flops at -30°F. (Though to be fair I had just been in a sauna)

@NitoriSmallArms @juan_krepecki @amer_icon It doesn't even have to be that tight, honestly. Totally normal everyday parts can be sufficiently affected. We do work for an outboard motor company and bearing fits in aluminum castings require us to monitor temperature and be really careful. 70°F vs 85°F is plenty.

[Seth Legare 🚀⚛️📯 @setbri]

@juan_krepecki @NitoriSmallArms @amer_icon Yeah. There was a part that we used to only make during the heating season, because our shop is not air conditioned and we couldn't hold tolerance in the summer.

@stormynormy42 @S1apSh0es In 1916 they ran it as a 300. That's the only one I could find with a shorter distance. They didn't run in 1917 or 1918 for WW1 or in 1942-45 for WW2.

@swagapinochet @Gryffix That reminds me of Dick Trickle the racing driver.

@JayBigGuy10 @cha0s10g1c That didn't stop the tech school I went to lol. The overhead radiators in the shop with cold water running through them just rained down condensation to the point that all of our lathes and milling machines got rust spots

@strkerb I've been paying attention since they were developing F9 landing. I can't recall how long I've been here on Twitter but I signed up to be up to date with the starhopper stuff.

@JaneWithSocks @QuarrySquatter @FishChampionn Dude I have an electric range that's 240V/50A. That's like triple the power of a British outlet. Of course I'm going to use a stove top kettle, it's faster than your standalone ones.

[Seth Legare 🚀⚛️📯 @setbri]

@Krissa_Kray_ Yep. Temp range here is -30 to -35°C and up to about 38-39°C. And yet my house is pretty much always between 17°C and 27°C. And that's without central AC. Even a cheap window unit is hugely helpful.

@Mackieangrybea2 @CyberWiz_YT Of course they aren't trying to make the vacuum engine work at sea level. That's not what it's for. It is however still the case that the changes they are making are making sea level operation more ok. In truth if they want it to be a true vacuum engine, it needs a bigger bell.

[Seth Legare 🚀⚛️📯 @setbri]

@Mackieangrybea2 @CyberWiz_YT My point is that they're making that less and less of a problem. The main issue with firing any vacuum engine at sea level is flow separation leading to intense vibrations and engine bell damage (thus the stiffener rings). As pressure rises, the flow stays attached better.

[Seth Legare 🚀⚛️📯 @setbri]

@Flight2Starship @CyberWiz_YT I'll bet a future higher chamber pressure version of RVac could fire at sea level. They are already so close that the stiffener rings are all that's needed, so I feel like 10-15% higher pressure could flip the math towards it being ok.

[Seth Legare 🚀⚛️📯 @setbri]

@Mackieangrybea2 @CyberWiz_YT With SpaceX pushing chamber pressures ever higher, that is becoming less and less true. RVac is already not far off from RS-25 in terms of nozzle exit pressure, and future versions with 350+ bar pressure could potentially be acceptable at sea level.

@SoundDepartmen1 @derpo377 Well none, but I finally understood that people that young actually can end up being widely recognized and respected.
