We have to admit that our first thought on seeing a Frankenlathe made from old engine blocks was that it was a set piece from a movie like The Road Warrior. And when you think about it, the ability to cobble together such a machine tool would probably make you pretty handy to have around in an apocalypse.
Sadly, surviving the zombie mutant biker uprising seemed not to be the incentive for [Paul Kuphaldt]’s version of the [Pat Delany] “Multimachine”. He seemed to be in it for the money, or more precisely from the lack of it. He was shooting for a zero-dollar build, and although he doesn’t state how close he came, we’re going to guess it was pretty close. The trick is to find big castings for the bed and headstock – Mopar slant 6 blocks in this case. The blocks are already precision machined dead flat and square, and the cylinder bores provide ample opportunities for stitching the castings together. The drivetrain comes from a 3-speed manual transmission, a 3/4-ton Chevy truck axle donated the spindle, and a V8 cylinder head was used for the cross slide. The tailstock seems to be the only non-automotive part on the machine.
We’d love to see a video of it in action, but there are ample pictures on [Paul]’s website to suggest that the heavy castings really make a difference in keeping vibration down. Don’t get us wrong – we love cast aluminum Gingery lathes too. But there’s something substantial about this build that makes us feel like a trip to the boneyard.
