what is this mystery pratt and whitney tool?
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: http://metalworking.com/Dropbox/P-W-1.JPG http://metalworking.com/Dropbox/P-W-2.JPG http://metalworking.com/Dropbox/P-W-1.txt 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 Bill - www.wbnoble.com -- Bill - www.wbnoble.com |

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.

Over the years I have seen many specialized tools that no one outside the trade could guess what they are for. Somewhere in my scrounge I have a tool for shaping the points on the end of wagon spokes. It's good for nothing else. Dan, U.S. Air Force, retired I've written Pratt and Whitney - we shall see if they have an answer - meanwhile, here is my latest "brilliant" speculation - the ground part is quite accurately ground to 1/2 inch - I just noticed that the flat part is tapered in width, it is .194 near the pointy end, and .144 right next to the ground round part. Further, the width of the flat part (until the very end where it is much wider) is .565. So, if you now imagine that this tool is slid into a 1/2 inch hole which has a keyway broached in it that is deeper than 65 thousandths, then the thing will enter the hole farther as the keyway gets wider - so that would make it a tool for measuring the width of keyways. Now, if my speculation were true, the ground 1/2 inch part would be just under 1/2 inch so it would be a sliding fit - so I got out my best measuring tool, an SPI digital micrometer that claims .00005 inch accuracy and I measured it - sure enough,. 0.49950 - so it is 1/2 thousandth undersize. This site shows some keyway width gauges http://www.jayeshentp.com/products.htm which don't look like this at all There is possible wear on the part that extends farther - it is .695 inches in diameter - and it goes from .18360 to .19220 - which nicely spans 3/16 (.1875). Ya think this could be it? |
