    That square hole, and what looks like a set screw in the item at the end oof the arm suggests to me some sort of radius turning device, it would possibly take a cutter. Since is is not very adjustable, perhaps not actually a radius turner, but something with a similar action.

      Regardless of its original use, it looks like it would be good for quick-n-dirty dividing jobs

        A sense of scale would help.

        Note that it is made of weldments.

          It sure looks like it could be used as a radius / ball turning attachment. Put a square toolbit in the end of that round thing and you have something that will orbit the end of a rod.

            The way striper plates work. Thay are mounted above the product, the punch comes down going through the striper plates, then punches hole in product, pushing the slug out, on the way up the product contacts the striper plate, it holds the product as the machine pulls the punch out. Without them product gets stuck on the punch.


            We used punch presses to put holes in box end wrenches before broaching them.

              I've been thinking that such trick might have been invented way before our time. I digress from machining, but for example the "Voynich manuscript" comes to mind regarding such a practice: a mystical handwritten book that has pages upon pages of unknown language and illustrations that have puzzled the researchers for centuries. Nobody has been able to make any sense from the writings and illustrations, nor have they found any resemblance to any known language. Even supercomputers have not been able to crack these writings. So it seems to me that we might have been tricked into seeking purpose where there is none to be found. Perhaps an ancient rich nobleman ordered this book as a practical joke and if so, then it must be the most successful one over ages

                He must have made those handle balls with it

                        Come on guys, this one is dead simple to ID.

                        It's a source for a nice worm and worm gear with a three ball handle attached. And at 40:1 it is a great start on an indexing head. The rest is scrap.

                        And if you look REAL close at an analog signal,
                        You will find that it has discrete steps.

                          A classic case of a thread wandering away from its topic, why don't people start a new one?

                            It’s actually two just items that I’m looking to identify. I’d appreciate opinions on either or both.

                              The doughnuts are "press pads" for pressing various sized small shafts, bushings and bearings on and off with an arbor press. The counterbores fit over a boss built into the arbor platform. They are identical except for hole size 1) so they fit over the special boss that was made for the press platform 2) so they all fit uniformly into the wooden case. I'm absolutely sure the previous owner would want whoever figured this out to have them...after you get them polished and refinish the case. I will PM you my address and gladly pay for shipping. Is my new arbor press still there? Thank you.

                                There’s another piece in one of the bins that might go with it. If it stays above 10 degrees outside today I’ll get out to the garage and get a photo.
