What's something that's seen as Obsolete, but isn't?
-
Every single leaf I or my wife has had broke. Very good when they worked though. I still use the twig on occasion.
Uh oh, what broke on it?
-
That leaf one appears to be $120 lol
Yeah, expensive up front, but the blades are cheap. I got on the Harry's train before they got bought up and were cheap. Now, whoever bought them has been jacking up prices, which had me looking for a cheaper alternative.
Harry's also gave me plastic guilt. There is a lot of waste.

The thumb screw bit.I still have one of the broken ones I can take a picture of. They did replace it without complaint the first time but just felt not worth it going forward.

Don't get the one I got, lol. I'm probably going back to a non-smartwatch after problems with my tic watch.
Oh yeah for sure it'll be an old fashioned normal watch. Ditched my smartwatch last year.

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.
Thanks, that's really helpful. I suppose it makes sense that not just material but cut size and bit would matter. They usually focus just on the geometry on YouTube.
Out of curiosity, what's the lowest you've ever gone? It's hard to picture machining happening at something like 60RPM.
If you want to get that through steam or electric motors or whatever that’s up to you
Since I'm interested in technological bootstrapping more generally, I think most about water wheels, actually! Steam engines need to be machined, which is a chicken-and-egg problem (or I guess crafted freehand to a machining-like precision, like Vaucanson's lathe). Electric motors don't necessarily, but they need a source of electricity, and that's either a lot of batteries or another rotating power source, which again doesn't solve the problem.
Waterwheels can be made with hand tools - maybe even primitive tools - and can achieve surprisingly modern efficiency and power density. They do require the right topography, but then again they spin indefinitely without needing to be fueled. 50hp is still a sizable wheel, near the top of what existed in pre-modern times, but I'm guessing you can do basic things with an underpowered machine.

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.

Apparently trains for some people

Hmm, good to know. I'll be sure to not overtorque it. Thank you!

...how are trains obsolete to anybody?
Hundred of billions of passengers and tonnes of freight are moved by rail each year globally.
This is what annoys me too. Freight is so crucial and it still moves plenty of people in many countries both in the north and global south. I guess they will think of steam era trains.

Why use IRC when you could use matrix
Because even IRC is better than matrix

CDs/DVDs/BluRays
I don't want to support Spotify, which is owned by tencent. I don't want to spend a fortune on streaming services. I don't want to sell my data to google by using YouTube, and I want to be able to listen to music/ watch movies when offline.
I love all of those things! Whenever I hit up a thrift store, the media section is my first stop. I've gotten so many great CDs and movies for next to nothing that way.
