Title: Possible aircraft tool find ?
Post by: EVILDR235 on July 17, 2014, 03:09:34 AM

I was poking around in the garage and found a possible aircraft tool.It is a 1/2 inch reamer that is 5-1/2 inches long.It is marked P&W Co. 1/2 G2. It has a 5/16 square to turn it. It may be a Pratt Whitney aircraft tool.Sorry no pictures.

P&W was around before the Aircraft Div was formed. I just started to sort a bunch of tap & dies yesterday and found a few P&W already.

I didn't about taps and dies for mfgs. names. I have a poop load of those tools and have never thought about who made them and for what. I do have some aircraft tools in my collection that i was able to trace down as such.

Would Pratt Whitney aircraft tools be marked P.W.A. ?

In theory, but I would be surprised if they made any. They were very busy making machine tools during the war which were in short supply.

Cleveland twist drill seems to have made most of the drills and reamers for the PWA series...

There's a history of Pratt & Whitney history at:

Including this about P. W. A.

1925    Frederick Rentschler approaches Pratt & Whitney, looking for funds and a location to build his new aircraft engine. Pratt & Whitney loans him $250,000, the use of the Pratt & Whitney name, and space in their building. This was the beginning of the Pratt & Whitney Aircraft Company. Pratt & Whitney's first engine was called the Wasp, completed on Christmas Eve 1925. The Wasp developed 425 horsepower on its third test run. It easily passed the Navy qualification test in March 1926, and by October the Navy had ordered 200 engines. The Wasp exhibited speed, climb, performance and reliability that revolutionized American aviation.

1929    Frederick Rentschler, ended his association with Pratt & Whitney Machine Tool and formed United Aircraft and Transport Corporation, the predecessor to today's United Technologies. His agreement allowed Rentschler to carry the name with him to his new corporation.
