So I bought a small box of tap wrenches, and it had a dollar general dial caliper in it, as well as this. The guy had no idea what idea it is, and neither do i, he seemed to think it had to do something with machining
The "roller has 2 textures and 3 different sized wheels that thread on.
It's a rasp with coarse and fine sides probably used for inside curves. This is more of a wood working tool but it could have been used for very soft metals or just about any plastics/polymers
Must people would understand better if you said file, but yeah, rasp is more correct.
I was going to make a joke, but I bet a lot of people legitimately didn't have a woodworking class in school anymore.
I was "lucky" to get a red state public education. We got woodworking, cooking, sewing, and boating, fishing, hunting licenses before highschool.
Missed a lot of shit we shouldn't, but that stuff is important too.
Hell, we should have taxes/financial stuff as well in there and basic electronics. A person graduating from public education should have all the skills needed to be a functional adult, and we haven't been doing that for decades.
your pretty right about that, when I went through are construction class was just taking apart bleachers, making porch swings and taking apart stuff to steal the copper, there was one time one of the freshmen cut the copper pipe to a dehumidifier, and it leaked Freon everywhere, ahhh good times. also, we used the money from selling the copper and benches to buy tools and wood for the next year. So it wasn't really wood working, but it was still pretty fun.
Other than cooking and I guess sewing. I can’t really see that other stuff being important.
No functional adult needs to be hunting or carving wood, it might be a fun hobby but it’s not part of adulting.
Fine motor skills are highly transferable and take a long time to lose.
Even the hunting bit was mostly "common sense" we learned out of a handbook for two weeks, it's not like we were going to gun ranges.
It's hard to argue in America it's bad to teach kids guns safety. Lots of kids live in homes with unsecured firearms and stupid parents.
But yeah, we don't need to literally have that for everyone. Just some shit that's actually hands on and not reading a book or staring at a computer screen.
It'd get used more than random dates from 200 years ago.
Financial literacy and small engine repair should be mandatory HS courses.
Yep, these rasp used to be used in my field for modifying the inside of prosthetic sockets, back when they were made of wood. I'm not sure if they were exclusive to our field or not, but I could probably find out what they were called in one of my books from college or one at my work if anyone is really interested.
We still use something similar , but it's attached to a big router with a long arbor arm.
