Technical Twirlie thing with handcrank

Very obscure (to me) item I picked up today at the recyclers. Handcrank makes the shaft rotate a half revolution then an internal clutch rotates it in another direction. Is this a shop tool?

 

Valve lap tool

 

Kinda looks like a old valve lapper.

 

the funky blade on the end fits into the slot in the head of the valve.

 

Sweet..thanks fellas
Albertson and Company, South City Iowa.

 

Most I've seen use a rubber cup where the blade is.

 

always wondered if I could use on for a wiper transmission.

 

Must be pre - Sioux

 

Notice that it rocks back and forth. Not spinning.








Bones

 

Some had interchangeable shafts with 2 pins, straight blade suction cup, etc on the end.

 

I'm still using mine. Identical to yours.

 

That thing is cool! All we ever had was a dowel painted red with a suction cup on the end.

 

Yes, I typed it wrong or the phone autocorrected to South... it's Souix City

 

Mine had suction cups on on both ends; must have been the professional model

 

Is there a source for new rubber cups for those?

 

It's still spelled wrong!

 

Yeah, it's Soo sitty

 

Sioux.......I stand corrected.
