    Repairing the cross-feed miter gear on an Atlas/Craftsman 12″ Lathe 

    I bought an old Atlas lathe on craigslist last year for $50. It was in need of a good cleaning and was missing a few parts, but all in all fairly sound. Joe made a replacement tailstock ram for it, and I’ve bought a new chuck and toolpost, and a few other bits. All in all it’s working pretty well after about six months of working on it off and on.

    One of the last features left to get working was the power cross feed. On this lathe, the cross feed is driven through a bevel gear set. The drive gear slides over the lead screw, and is supposed to be driven by a key that engages a slot in the lead screw. The bevel gears are ZAMAK castings, and the key appears to have worn away or broken years ago.

    Ben's birthday present 

    Here’s the video of the first thermite test. Molten iron!

    This was early August 2012. We bought the aluminum powder and iron oxide from Skylighter, an online fireworks supply company. We bought 2 pounds of aluminum, so there’s a whole lot more where this came from!
