- Geometric Tool Company, of New Haven CT, was a subsidiary of Greenfield Tap & Die in the 1950s. GTD merged with United Tool and Drill Corporation, of Cleveland OH, in 1958.
These combined companies became part of TRW (Thompson Ramo Wooldridge Corporation) in 1963.
This 1977 film promotes the Geometric Tool Division technology. Unfortunately, color film from 7 film promotes the Geometric Tool Division technology. Unfortunately, color film from the 60s often used a cheap color process which faded easily with time. The color in this film was almost gone at transfer time. We apologize for the imperfect color and contrast.
Clearly this chanel is a dream for machinist.
Dang, that's level 9 mechanical genius!
I just discovered your channel yesterday and wanted to give you a big THUMBS UP for bringing us the content you're providing. I totally love the historical stuff and the connection to the old companies in the area. Keep them coming and I'll certainly keep watching and clicking on the thumbs up.
Abom79 got me here. Subbed.
"then the chaser abutment screw is nipped up"
A Cessna 310, a Cessna 210, a Lockheed C-141, and a Boeing 727 in the opening sequence.
Im stuck in a time loop, it seems, because I use these exact threading heads daily. My Geometric head is a 1-1/4 DDSA and my Warner Swasey is a #3 M2200. Great Video!
I swear i used to listen to this same guys voice narrating HVAC instructional videos back in 1990 at Northeast Metro Technical College.
Came over from Abom's channel. Our company still has a 40s era machine shop since with sand cast machines with war dept serial numbers. Looking forward to seeing more videos, thanks!
The copyright at the end reads MCMLXXVII = 1977.
another gorgeously-photographed jam handy production! thanks for uploading
Abom sent me over. Sorry I never heard of you. In the process of starting my own museum. Love saving old iron. The bigger the better. To much of our history has already been lost !!!
Nice to be watching this video as a current user of two die types here in our shop a Geometric and the acorn both do a die thread cutting job for us, while the die head by Geometric Tool Company is best known for being an auto release when used on a turret, there is a lesson we can share if permitted.
Came over from Abom's channel.
Hi from England
Subbed -- Compliments of Abom79 channel. Adam sends his best!!
I like my Geometric Head, but my Namco Circular Chaser head is far Superior, in my opinion, because you can sharpen the chasers hundreds of times.
1970's? 1980's? Could you please teach me
beutiful machines in this time but now with the tread rolling machine are go faster and make the piece harder
