I picked up a dividing head understanding that there were problems with it (price was right!!).
There are no stickers, badges or embossing to identify the manufacturer.
She spins smoothly, but doesn't rotate.
On partial disassembly it appears that the casting may have been overtightened.
This resulted in cracking the internal casting, and wedging the broken pieces against the frame and preventing rotation.

If I'm able to separate the casting from the spindle and main, then I've got a friend who welds and brazes for work (he's really good) then we can get her patched and machined.

I've got the worm gear off and the barrel removed from the frame.
But, now I'm stumped. All the visible bolts and set screws are loose or removed. I don't want to apply force unless I know and understand which direction and how much. There is no rust.

Does anyone recognize this dividing head, or have recommendations for disassembly?

Thanks!!

WOW she really took some abuse.
Unfortunately I dont recognize it. I had mine apart last year but it is significantly different.
Wish I could help....Good luck.

I have a L&W chuck that looks like it but it doesn't have that rectangle block on top. I think someone here did a complete rebuild on one.

I was looking at the 4th Picture.
Are those bolts SHCS that have the Head snapped off?
If so can you Use a Left hand drill in a Hand held cordless drill to remove them?

Your, question and my pics made me go take another look.
On very close inspection its only the bottom of the drill hole.
However, I wonder if there are set screws/etc under the two oil cups?

Hmmm.
Thanks for the response?

Got her disassembled!

Took her to an elderly gentleman who I am aware of.
He furrowed the eyebrows of his wrinkled forehead, and squinted at the part for about 20 minutes, examining it from every angle.
Picked up a hammer and tapped her multiple times in strategic places.
The answer was very simple, to him.

The cracks are more severe than appear on the exterior. They wrap 2/3 around the inside of the dividing head.
We discussed multiple options for the repair, including brazing (with pre-heat), V groove TIG welds (with preheat and annealing), fabbing a new one on the mill and lathe, or accepting the one of many he thinks he "might" have in the barn, free of charge.

I'm supposed to return in a couple weeks when he has the energy to walk out there.
I believe it is a test of my worthiness.
Kind of like pulling the sword from the stone (King Arthur).
This will be great fun.
