✅ SOLVED Mystery tool

[Minrelica]

I found this in a back room of an old timers antiques shop.. no tag, no description. He didn't really know what it was either so he gave it to me for free.

What I do know: It's missing an attachment that would have slipped onto the end of the shaft. When you crank the handle, the shaft turns about 180° then starts back the other way about 45° then 180° the other way and so on.

Snake, mixer, hole reamer, drill?.. There are no markings, no patent #, company name etc.

I figured someone here may know what it is. Thanks!




Length 10.5 inches

i think it's a valve lapping tool

Yes, a valve lapping tool, for use on gasoline engines. It would have had a suction cup on the end to grip the valve.

Thanks guys! Doesn't look like they've changed much over the years

We used one just like it when we restored my 48 Indian.
