Hello All,

It is a very long story that I will not type. But it all relates to this unusual tool.
The most interesting thing about it is that when the hand crank is turned the
shaft rotates one way for about 180 Degrees and then is turns the opposite
direction by 360 Degrees. Then back to 180 and then the other way 360.

The Degrees are not exact every time so there is some +/- to them.

The Hand Crank will turn either way. Clockwise or Counter Clockwise. The
Rotation is smooth until the the shaft direction changes where there is a
detent of sorts when it changes.

With the big knob it give me the hint that it would be held against your gut
and the flange end is connected to something like a "rope"??

Ok, so now I will stop this typing with the big question!!

What is this TOOL used for?? And what is it CALLED??:unsure:

Thanks to all for your thoughts!!

OK, here are a few close up shots.
Please not the part that is attached with the single screw.
The very end shows signs of wear as if it was drilling into something.
Also note that this end "tip" can be shifted from side to side within the slot.

Very odd tool to say the least.
Thanks for any comments!!

The logo actually looks better the opposite position.

So where or who is Gonzo?? :unsure:

He's that guy that likes to laugh at people who don't know what they don't know. I wonder if he knows if he knows what this tool is, or doesn't know if he knows, or knows if he doesn't know?

I think he sells books or seminars or something.

Back to the tool, I'm thinking some kind of drill, too. But I can't figure the purpose of the joint at the end.

I would consider that to be a valve lapper, not grinder.
Typically valves are ground on a machine, as are the heads. Then they are fine tuned by lapping. The most common way is to use one of these:

Ok, this is very interesting.
The description in the No. 238 Valve Grinder that you get a compete revolution with 10 cranks
does not comply with this specific unit. It is very hard to describe except for what I said previously.

The other interesting thing is that the original cost was just $3.40. At a labor rate of .10/hour??? or Less??

I guess I have to find a place to put this thing for "Display Purposes Only"!!!
Thanks for the quick result guys. I really had concerns that this would have taken a lot longer to resolve.

Have a good rest of the week!!
