    Tool Lathe Stops

    No, mine is quite solid. I have the adjustment screw set such that the saddle stops before the indicator bottoms out. It takes a bit of effort to move the clamp unless the feedscrew was being driven under power, and when that happens it slides as expected. The clamping screw has a bronze...

    Shop Microwave metal casting - some of the best videos I've seen

    Silicon carbide grit is available from any lapidary supplier. The grit size matters (not too coarse, not too fine) and I have acquired a 5lb bag of 150/220 grit which is perfect. It is known as Stage 2 grit if you're looking. Harder to source in any quantity is the sodium silicate (water...
