You’d be surprised how slow machining can be. Cutting speeds are all in sfm (surface feet per minute) and when you have a BIG part, them feets add up quick. Check out videos of big old vertical lathes running big parts. You can get down to a quarter of an rpm but the flange or fitting is so fucking huge that you’re still pushing 100-200 sfm at the bit.
There are no “typical values” when you’re running a mill or lathe. You could look up “speeds and feeds”, but that’s really just a table that you plug into an equation to figure out how to set the machine. It all depends on what you’re doing and what you’re doing it with. Drilling a hole with a high speed steel drill bit is going to be a bit different than drilling it with a carbide spade, and all that is going to depend heavily on whether you’re trying to run through titanium or tin. You need to fine tune running “x” bit through “y” material for a “z” sized cut.
Essentially, this is the knowledge that separates skilled labor from manual labor, and machining is (was, RIP cnc button pushers) skilled labor.
At the end of the day for most metal machining you’ll need between 50hp and 100hp to be up to modern standards. If you want to get that through steam or electric motors or whatever that’s up to you
Torque is the real limiting factor. You can always gear up or down for whatever you’re working on, but at the end of the day you need enough torque to get the work done. And a proper milling machine needs A LOT of torque.
You don’t need an electric motor. You just need enough spin. I’ve seen old mills and lathes that run on steam. An electric motor just happens to be very convenient with our current technology.
Sure, but it’s not as impressive (imo) when you also need a computer control system, a bunch of circuitry and electronics, and a whole mess of software to make it work in the end. A mill just needs enough spin and it runs exactly as intended.
Pretty much anything in a machine shop made in the last 80 years or so. So many people turn up their noses at anything that isn’t computer controlled anymore. Yknow what a big old mill can do that a CNC can’t? It can make every single part needed to make a new mill. It’s a self replicating machine with the right know how. People don’t respect that kind of quality anymore.
Why bother with gas if resources aren’t an issue? Something savagely luxurious about cooking over wood. Primal but decadent.
I’m just happy ig is letting porn through. Cooters and hooters out and about is an indicator of a healthy social media environment
Lmfao. You don’t beat the system by obeying the system. You burn it to the ground a build a new system, with hookers and blackjack.

Donate to Sikh kitchens. Core tenant of their religion is simple acts of kindness for the sake of being kind. They take everyone in at Sikh kitchens. Even cities in Texas and CA that like to ban feeding the homeless can’t do shit about these kitchens because it is recognized as a part of their worship.
Man that is a hard take. Amy Shumer is a female clone of nick swardson minus the creativity, which is miniscule but significant in this comparison. Both of them peaked at high school humor and never got over it.
Why limit yourself to real materials? Just whip up a few hundred thousand miles of superconducting cable and then set your price.
If you have to quibble about things being possible, just figure out graphene batteries/capacitors and you’re set forever.
The term “air sickness” comes to mind
I had to check i wasn’t in a brandosando instance with this blatant fan interplay
Pushing Ice by Alastair Reynolds fits pretty well. I like the progression of figuring out how to survive and thrive as their situation changes. I also quite like how the book deals with questions like how sentient species might interact despite the vast gulf of distance and time that exist between their civilizations.
Doesn’t an ionic air moving system like this put out a big ass EM field?
Im a fabricator who don’t fuck with the lecky, but maybe someone more educated than me can explain why this doesn’t wipe your memory every time the cooling kicks on
I always win at tragic backstory.
My dad won box tickets to the last 49er game at candlestick through some radio contest. All expenses paid, bunch of merch, got to meet some players, whole VIP package. Happened to be that the last game at the stadium was a few days after my birthday and a couple days before Christmas. I even happen to live in the area while he was flying out from Texas.
He got me a card with $20 in it and took his mom, stepdad, and ex wife with him to the game. Killed himself about 8 months later. Thanks pop.
You gotta fight the dick stuff with dick stuff. At least I know where my dick stuff has been
The bigger problem is that genuine law enforcement efforts are discouraged from actually catching pedophiles because they often end up being constituents of those same cops, either politically or socially. It’s either a priest, a super PAC donor, or another cop on the other end of that investigation.
