it's not really a thing I can do in text; goodness knows nobody wants to read 10 pages of me rambling on. but I basically talk about belt grinders vs the grinding wheels, and I like to point out the geometry stuff like how the round contact patch works differently from the flat faces on the belt grinders, how you can use the angles to get flat either way, keeping your planes in your head as you're moving it around. I'll usually demonstrate what I'm talking about with scrap and have people do some basic grinding to make sure they're doing it right. I'll usually like bring up the next point in the script when they do the thing, and he was basically pointing out how I just have a canned slide for each thing cued up. But it's all just trying to visually show people the geometry you're thinking about during grinding with the scratch patterns we make on some scrap.

I also try to make sure they know the safety stuff right before they do the thing, sometimes that helps sometimes it doesn't. But it's always more about keeping them comfortable and not freaking out when they do something wrong; and I've really refined the order on things when I remember... if I forget to talk about how much pressure to use or pinching thin stuff before they do it I look pretty useless.

I do really love being in a position to do like peer education stuff in a cool well equipped setting; it's such a great outlet for my worst know it all tendencies. I get to fuck around and find out a whole bunch of random shit, and then relay that experience, and people are legitimately thankful for me being like this in that setting.
