    supershargers

    Taken an air motor apart lately? And from one of our favorite irreverent personalities. I needed a small pump one day and didn't want to go to China Bay let alone to the box store. Since I had a surplus of air die grinders around (30 or more, it's a thing here) I took one apart and proceeded...

    WTB Benchmaster/Duro mill

    We all know what they are and how difficult they are to come by. Deep cosmetic repair and even complete rebuild is not beyond my skill set. As long as "most" of the mill is there I'm willing to sweat details like replacing with ball screws, scraping ways, even weld repair. I have no issue with a...

    https://www.farmcollector.com/steam-traction/the-african-queen A fair photo or two but I believe the original was a turn of the century Brady. I recall one still in use as a stationary plant in a single shaft machine shop/saw mill in Holy Loch as late as the '70's. Sorry that's all I've got...

    Morse tape in lathe.

    If you're going to quote Tony you might as well just do it verbatim. http://www.lathes.co.uk/delta%20metal/ My own limited experience with the lathe was motor/pulley alignment. Do get it right. The variable speed mechanism depends on following the installation directions to the letter. If...

    Better Gibs for mini lathe

    I had a conversation with Joel (if that needs an explanation-ask) The result was new cross and compound gibs for my MK II Atlas. The lapping of the gibs was a work out. Remove the lead screws and assemble first the cross and then the compound. Remove the obvious high spots, damage, abuse, and...
