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

      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.

      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.
