Threading Time - The Story of Die Heads and Taps
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.
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.

Thanks, Bruce! We have a half dozen or so remaining industry films remaining. Then we will need to hunt for more. We digitize and restore these films with our own equipment. We would welcome any loans of vintage films from other collections! We then plan on producing histories on other important industrial subjects, especially related to the history which defines our home area. Be SURE to watch our rare 1943 Millers Falls Tool Company film.
Dang, that's level 9 mechanical genius!
another gorgeously-photographed jam handy production! thanks for uploading
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!
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!
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. We actually have and utilize the smallest Geometric die holder the company made, to this day, it is not an automatic it is the companies only non automatic version they made. We are more of the 12:00 minute into your video size yet even much smaller. What you have to do is run the die down the thread to a marked spot hit the spindle stop (large buttons) once stopped hit reverse, while it is built well it is too small for automatic for those times, it is the only non automatic Geometric die the company made. We see that Turret on that larger lathe in your video, that is a very large to us lathe and turret or capstan we run ours, a capstan turret on a micro lathe Instrument bed sized, make in America at the Louis Levin & Son Company in Southern California. Nice to get to watch this video, and it is nicer still yet we know now it was made in New Haven CT. Thank you and the Museum or our Industrial Heritage for the share, we are two thankful guys. Lance & Patrick.

Came over from Abom's channel.

The Jam Handy Organization were masters of education and promotional films. Many famous film industry people worked there, including Max Fleischer (of Betty Boop fame) and Disney animator Roy Williams, who some of us might remember as the big Mouseketeer from the "Mickey Mouse Club". All of the music and establishing shots (such as the airplanes) were from the talents of the JHO. Another film, in this collection, is the 1952 "Facts about Taps and Tapping", also a product of the JHO. The introduction in this film exhibits medieval armor which was probably shot at the now closed Higgins Museum, in Worcester Massachusetts.
The copyright at the end reads MCMLXXVII = 1977.

That's right! I'll correct it. Thank you.
Subbed -- Compliments of Abom79 channel. Adam sends his best!! Greetings from Belgium (EU)
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.
beutiful machines in this time but now with the tread rolling machine are go faster and make the piece harder

Mostly for High volume Nuts and Bolts. These threading heads are perfect for lathe production.
1970's? 1980's? Could you please teach me
