  • I’m real tired of “strongest material” being thrown around. As a welder turned machinist, “strong” doesn’t mean much of anything to me. Aluminum is plenty “strong” but it’s softer than some woods. Tungsten carbide is harder than a coffin nail but you can chip it by looking at it funny sometimes. Kevlar is plenty tough, but it isn’t hard or particularly flexible. There isn’t any super material that will ever do all the things “the best” and throwing around meaningless titles for clickbait feels childish at best and exploitative at worst.

    They do eat to ticks, but they’re resistant to Lyme disease, not rabies. It’s not that opossum hunt ticks or anything, they’re just real good at grooming, and as ticks are real good at sticking to furry critters, opossum naturally end up fighting both ticks numbers and Lyme disease incidents.

    So, yeah, same same but different.



  • 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





  • 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.
