This thing looks way overly complicated and kinda dangerous. Gotta be a homemade thing,I mean it's just so insane looking.
I'm just stunned by the fact someone built this thing.
(I'm hunting for a cheap used saw)

The saw looks like it would be messy. No pan to catch the cut offs and water. I can see where it would work great. The sphere machine looks like grit could get in the motors, being under the grinding and grit head. Otherwise, it also looks good. Ken

A pan would have to be set under the sphere to catch the grit slurry and a water drip set up. Looks better than the saw.

Not really a saw. It looks like a crude version of the stone lathe that Barranca makes. The saw blade will take the sharp edges off of the rough sphere, and prep it for a sphere machine. Might be an interesting machine to play with, if someone has a big sphere machine.

Sphere machines are covington design copy`s

I thought of the rock lathe (actually Diamond Pacific) too but there is no pattern for blade to follow. Looks like the vise swivels to make the many cuts to me. I've seen a few drop saws set up with swivel vises for spheres and they work well.

Hey John, blow the pic up big, and look at the far left side. Looks like there's a gear motor at the top, and some sort of chain drive at the bottom to move the saw. Possibly missing an idler sprocket. Don

Weird isn't it? You would have to use a thick tile blade to use to grind off the points if it is a preformer. Maybe it does both (cut angles and grinds points)? Maybe you should buy it Don and figure it out for us. Then you can buy my sphere machine to have a complete set up.

If I used credit cards, I'd be tempted to bid on that thing. It would be fun just figuring out how it worked. After studying the pics several times, I'm convinced that it was a production machine. Probably limited production. Too many well machined parts to be something thrown together in somebodies garage. A couple of things that bother me are switches hanging on loose wires, and a cover missing on one gear motor. Looks like a few missing parts. But it would be a fun project for someone who likes vintage machines. Don
