Mystery Parts

The dividing head is an indexing head, but a pretty simple one. Used with a milling machine, shaper or planer, surface or cutter grinder. A true dividing head has gearing and index plates that will allow a variety of indexing options. This one is limited to the number of teeth on whatever gear is installed on it. Should have a tailstock.

Misc1 - upper right: quill adapter for a drill press to allow mounting hollow chisels for mortising.

Yeah, it should have a tailstock, unfortunately it doesn't. It's also missing the split cotter lock for the spindle. ;-) Any idea who the manufacturer might have been? Atlas?

That was my thought as well, but the finish is the same as the other parts in the picture, which made me think it might have been something else, but I can't see how all those parts are related. You're probably right.

Thanks

Pete

I've got one with the tailstock, in really good condition, and could not find any data indicating who made it.

Jon

Nice! Did it come with extra indexing 'gears'? If I had a mill, I'd make some parts for the one I have.......

Pete

These are parts from several things. The big yoke is part of a drill press mortising rig, and the block with clamp and the forked bit are from an atlas wheel dresser for a tool post grinder.

Paul K. Dickman

Great! Might be worth cleaning up and finding some parts for. Thanks!

The wheel dresser makes perfect sense. I hadn't thought of that. Could the 'grinding rests' be for sharpening end mills on the same set up?

Thanks alot!

Pete

Hmm ... could it mount in place of the compound? If so, it might be part of a radius turning setup. I think that one of the other pieces in the same photo (the part below it with the slotted arm) may go in the upper (small) end and turn a HSS lathe bit to cut the radius. That fitting would be for negative radii, while another one (with a crank-like design) would be for turning positive radii like balls.

Enjoy, DoN.

Specifically, one manufactured by Atlas as an accessory for the Atlas milling machine.

Most are made to work withselected gears from the threading (crossfeed) set.(Change-gears)

Pete, I have a tailstock that matches!

Pretty close to the matching paint chips!

Wanna make a deal? Either way?

If you were inclined to be parting with the headstock, we might make an arrangement, as I have a small mill it would fit.

If not, we could deal on the tailstock...

Definately Atlas!

Email me if you want to see the pictures.

That's it! But without the tailstock. Thanks Kevin.
