Albertson Valve Grinding Tool

[Ayrhead]

Hi Everyone. It was suggested I start a Thread for this tool. Apparently it could be an oddball type of tool

Valve lapping tool. I have what appears to be the same but branded Craftsman.

That's the best place to start if you're looking for information about a vintage tool or tool manufacturer.

The second-hand market seems to be glutted with those devices, made by a number of different companies, like Don's "Dunlap" just above.
I would not be surprised if there turned out to be some kind of "valve grinder collector" club somewhere.

Everyone made one of these. I have the Blackhawk version of the same tool. Nobody seems to want them and most have no idea what the tool is used for. The last one I saw at the flea was a Craftsman and priced at 3 bucks there were no takers.

I don't know why Albertson cited the Hazeltine patents in the SIOUX valve grinders. The underlying mechanical concept of alternate gear sectors providing reciprocating / partially advancing rotation was used by multiple valve grinder manufacturers. The SIOUX grinders had their own set of patents which were somewhat couched as refinements / improvements on the provisions of those earlier patents. My father-in-law was still using SIOUX hand-held grinders for engine tune-up (flathead FORD & two-cylinder JOHN DEERE ) in the 1960s. Regards, Stan S.

I picked one up from a dollar table yesterday. Then saw two on a different table at $5ea. I have seen them before and not purchased, but for $1, I figured I could satisfy my curiosity.

They're fun to open up and see the reciprocating action. I have a Duro and a Zim.

Here's a pair of combination valve lappers/ breast drills. The reciprocating valve lapping motion can be switched off so the tools can be used as a regular breast drill. Ashcroft on the left, Mifco on the right. I wasn't responsible for the red and yellow color scheme on the Mifco.

I have the same Albertson Valve Grinding Tool. They used to be common, now I only see than at garage sales and swap-meets.
I like the valve tools WisJim posted.

I got one from a tool kit included with a WW II generator I bought 20 years ago.
