I've mentioned before that I came home with a Hauser 2A3 Jig Borer in addition to the Deckel FP1. It is a really interesting small jig borer, with a MT 0 quill, and has some interesting accessories (centricator, optical centering attachment, collet arbor with collets, Albrecht chuck, and a few other MT 0 threaded arbors).
It evidently had been sitting some time, judging by the waxified grease inside the head. I took the head apart, replaced two bearings, cleaned & re-greased everything, and got things working the way they were supposed to. I was very impressed by the design and attention to detail. The head's input shaft has a hollow core, with an internal shaft that is geared to the 150-3000 rpm speed dial. i.e. the internal shaft normally is fixed and is rotated only to set the speed.
I don't have a manual for it, so I am figuring out how it works by taking it apart. That works, but there is undoubtedly a better way to go about it. I'm puzzled by the transmission device (egg-shaped cast housing which the input shaft with internal speed control shaft originate from). I haven't taken it out of the machine, but I'd like to have some inkling of what it is and how it works before I tackle it or choose to leave it alone. If anyone has some information on it I would love to hear some details. It is located in the upper arm adjacent to the head, and it is about 12" long, 4" dia. with a finned egg-shaped casting.
thanks-
