This was Grandpa's.
Near as I can estimate it is late 30's early 40's.
Very little end play. I'd guess 1/32nd to 1/64th. Sorry, too lazy to figure out how much.
AFAIK-Madison Kipp contributed to the war effort. Not sure if Grampa worked there, but he was a tool and die maker in Madison, so a pretty good chance he did.
This may be an early type grinder-maybe a prototype?
If I'm not mistaken Madison Kipp developed a lot of new technology during those years, and also shared the technology with other industries. (I probably have that all wrong, just how it's in my mind now. Love to hear from the historians on that one.)
So, my question is, if it is a historical piece, I probably don't want to be using it. Correct?
If not a historical piece, still is it ok to use it? Or should I conserve it as a nice collector. Have been surfing Ebay off and on for it over the years. Never seen another like it.
Its been well stored over the years.
Still has nice smooth bearings, but feel like a little dry maybe.
What kind of lube? I have some A\C comressor oil. To me that ought to be perfect for the job. Just a few drops and rev slow for a bit?
Should I take it apart for inspection, make sure no problems? Or just run her till she drops?
The box looks military issue. Probably something he had and adapted to the task. Nicely fitted so the tool is held securely. Lots of grinders. Given the warning on the barrel, can I use other bits with it?
hard to see in the photos one side of the barrel says Kipp Air Grinder, other side says Model JA, series no 50.
and a patent number on the taper. Inside rear bearing collar states working psi.
