Got this at a yard sale. i was told it is a tachometer for an old treadle lathe. made by Starrett tool co. Does anyone know if thats what it is and how much it's worth. The dial turns when the chisel shaped shaft is rotated. second post is pic #2

Thanks for the help!
Paul, I don't know about it being for a Treadle Lathe, but it is a mechanical tachometer. I have one from my grandfathers old tool box. He was a High School Metal and Machine Shop teacher, so along with the tach, there was abunch of other neat stuff to.
I don't think they're worth too much, but in my case I will probably use it occasionally to verify rpm's on a lathe or drill press. Of course it also is a reminder of my grandfather whom I respected very much.

Paul,
You have a "registering speed indicator" made by the L.S. Starrett Co. of Athol, Massachusetts, possibly their model No. 107. By pressing the pointy end (which could accept variously shaped rubber tips) against the center of a rotating shaft for a measured time interval, the revolution count divided by the time interval would produce an RPM calculation. In your second picture, the outer dial counts up to 100 revolutions and the inner one keeps track of (i.e., "registers") the 100s.
These interesting tools are not particularly rare; I've picked up a couple at tag sales and passed up a few more--but they're fun to fool with.
Enjoy,
John
I paid $10- too much or too little? I just thought it an interesting item.
Wow! The knowledge of you guys is fantastic.
I inherited one of those things. I never could figure out what it was for--even though it was, and is, in perfect working order.
Great! Now I have another tool that I will probably never use.

Paul, can't say for sure, but I would $10 was a fair price. They are kinda cool, and they can come in handy every so often.
Have fun!!

Paul, that’s a pretty cool tool, besides, ten bucks will only get you 2 beers & change in one of the trendy Taos nightclubs.

Ya, it's interesting- never go to those 'trendy Taos niteclubs' (too far) and $10 for 2 beers? I get a 12 pac for that and enjoy it while I badger you guys!Originally posted by Bruce Page

Thanks!
Sounds well within the range of the unembarrassing, if the mechanism still works. I've seen 'em for lots more and lots less--most sellers haven't a clue what they are either!
Spin away,
