I originally posted this in the metal working newsgroup, some folks
there thought the part might be recobnized by somone here - so, it's
worth a try - any clues?

thanks:



I think this is probably quite old, but so far I have no idea what it
is (or
was part of) - there is another like it that has been sharpened to
use as a
boring bar - clearly that was not its original purpose. the one
pictured in
the drop box appears to be original - but orignal what, is the question.

here are the links to the drop box:

Anyone got any clues about this item?

The text file from the drop box is reproduced below:

Mystery Pratt & Whitney tool - the cylindrical shank is exactly .500
inches,
it says on the

shank, the following:

NO. 32
HS.-36
E-12

P&W
MFD CT
Made in USA

it is NOT a drill bit. The part that extends beyond the 1/2 inch
diameter
shows a wear line

like it was riding in a keyway. The point seems to be lathe turned,
the 1/2
inch shank

appears to be ground

My first guess would be some sort of gagueing equipment. I have run
across quite a few truly odd P&W gages and accessories for gage sets.
They were willing to make some very specialized gages for a lot of
unique applications.

Yes, I would agree, though I think it is not a specialty item - maybe
part of something to measure camshafts and the like? I'd love to find
someone who could say for sure what it was


Specialized boring bar? The 1/2" round end reminds me of my boring
bars, but I have never seen a cutting end like this thing has. I suppose
it could be installed in a boring head and used to cut a groove beyond
the reach of standard lathe tools. I'm probably way off, but I can't
think of anything else.
