    Tailstock Fundamentals

    This video is made by HAAS. I find their videos very informative. Even though they're on their CNC machines, most of the content can be applied to manual machining.

    Heat Treating

    I had to make a small part from AISI 4140 steel. A couple of fire bricks, propane torch, and quenching oil (ATF). Heated the part to cherry red (though, I've never seen cherries that colour....maybe maraschino cherries!) In the picture it's a little orange: kind of hard to hand hold the...

    Cross-Slide Leadscrew & Nut

    Half-Nut Engagement

    I always strive to improve on my techniques, either doing better or getting faster, or both if possible. Here is the scenario. When cutting a thread with the lathe, we have to engage our half-nuts so the carriage locks onto the lead screw and away we go until we disengage the half-nuts...

    Starrett vs Mitutoyo

    Well not an exhaustive comparison but.... Last year I picked up 3 used Mitutoyo micrometers at a fantastic price. When I took a closer look at them, I was a little disappointed, not their accuracy (I havent checked them yet), but in their build quality. They all have holes in the frame...
