Polish dividing head

workplace purchase from recent auction at local metal work da Tory that went out of business, Ramsey Machine Works. No keen competition on the bidding on this item, I think we got it’d for 175 bucks. It looks like a very close copy of a cincinatti dividing head. It’s heavy, I can’t easily lift it and it take two to place it on the mill without bursting a gut. 

Branded as Huta, nothing on the net about it, but the company was, or still is, an arms maker. Has the cool inner ring mechanism that I think makes 400,000 possible circle divisions. 

I’ve used it already to make product. Cut the machining time down for a particular operation by… Well what took me an hour with my cobbled together jig now takes 20 minutes.

All old school stuff but so very cool. Btw, I just cleaned it up enough to use. Still needs some spit and polish ( no pun intended) but I don’t think I will be taking it completely apart any time soon.

    The system for dividing looks very interesting. Could you do some more detailed photos?

      Hi john,

      Yes it s a great tool. Used it already to really speed up one particular machining chore I have to do at work. It’s pretty well a direct copy of a Cincinnati 12″ ( not quite sure of the sizing). Right now I’m haphazardly cleaning it while it sits on the bench. Not a real full on clean up, just trying to get the years of fab shop grit, dirt, oil, coolant off. I’ll write another post about it and post some documents pertaining to the cinci original.



      Ps glad you commented on the tool. I guess you can tell I really like it. There are a couple of other old school tools worth bought at the auction worth mentioning and I plan on posting something about them too.

        I have checked out the Cincinnati book on milling. There method of doing high numbers is by means of another set of dividing plates. These look as if they are of a larger diameter than normal.
        The twiddly bit on yours looks more like the fitting on old brown and sharp dividing heads.

      Hi there,

      Yes it is and very well made. It does appear to be very similar of not a close copy of a Cincinnati dividing head. I’ve heard stories about how that might have come about, but nothing definite.
      I can’t find anything about this particular dividing head, made by Huta.
