Why is it these old educational movies teach more about their content than any other educational films out now? Please don't stop releasing them.

This was not only a distinct visual treat but a surprising learning experience. That tandem tap in particular is remarkable.

Just bought my first set of Vintage Greenfield taps and dies. I love these old-school educational movies and the time they harken to. As a blacksmith, I have a passion for days gone by, obviously, and love a chance to learn something. Even though I don't have a lot of call for threading steel here in the blacksmith shop (Three Rivers Forge), I've been looking for an excuse to do more! Sadly, in the blacksmithing realm, I see a lot of folks either using all-thread that they bought at the store, or welding a bolt onto the end of a rod tog get some thread. Neither is satisfactory to me, so I thread rods and make custom one-of-a-kind nuts and bolts. Anyone can go to the hardware store, but only someone who knows a good blacksmith can get truly awesome ironwork! :D Thanks for posting this movie. It was worth every minute of my time and I've already shared it with the blacksmithing community.

Dare I say, these taps are far more superior than most of today's tap quality.

The slow motion lathe cutting tool shots in this video are awesome!!

Excellent! Reminds me of my apprentice days at H.F.Jensens Værktøjsfabrik (H.F.Jensen's Tool Factory) in Copenhagen, Denmark where I learned the fine art of tap and die manufacturing in the early 1980's.

Love how everyone from scientists to engineers wore a white collared shirt and tie... old school.

Yes, a much needed video for novice to learn and experts to remind. Thanks to Mr. Whitworth. Additionally, here are my experience on pre standardized British taps and dies in my lifetime. I have restored many pre WWI And WWII English motorcycles. They were assembled with non standard screws made from non standard dies and tapped holes made from non standard taps. This resulted with NO interchangeability of screws to threaded holes. On reassembly you needed to put the SAME screw into it's EXACT tapped hole or they could be not fully seated. Worse yet the threaded holes could be too loose and strip out when tightened. This was before British Standard. On English motor cars the hardware standard changed to SAE in 1949, the same as in the U.S.A. You actually found late into the 1960's British Standard hardware on gear boxes, rear ends and steering assemblies. On gages and hydraulic fittings you still might find Whitworth threads into the 1970's. I still have complet tap and die sets in SAE, British Standard and Whitworth. Additionally Metric tap and die sets in both Japanese and European standards. Of course sockets and wrenches in ALL standards. I am tool poor. HaHa! In my next life I don't want to reincarnate until there is a World Standard. HaHa! Happy Holidays and God's Blessings.

My baby boy became super relaxed while/after watching this. I'm saving this video!

Beautiful video. Thank you for you efforts preserving and presenting this material. It’s amazing something so seemingly simple on the surface can be so complex.

This film is so true and useful for an Apprentice. Then you applied your Skills and worked different Jobs for Experience and developing your Machinist Skills. For a Job Shop, Time was Money, every Day after Day. When you worked in Production, same part, different day for months and months. Then R&D, different part, every day for days and days. Later, if you were good, you worked as an Engineer, Pencil & Paper, until you went into Management. Same thing..."When will you finish the Project?". I enjoyed being a Machinist.

This is a great channel . I still have several sets of greenfield taps. I enjoy the old shop films and books great to find them ! My Dad always said to me if you want to learn something new study the old! I wish I learned 1/2 of what Dad knew !

Appreciate how beautifully shot this film is! Not even the most ambitious machining youtubers approach this level of perfection in camera, light, object and background setup. Look at 22:58 where it shines though that the cinematographer thought he was working on a feature film drama. At times when the cost of film stock and post-production was significant, I guess it was reasonable to spend a little on the rest also.

I got a set of tap and dies sent to me by mistake by a seller on eBay instead of the router bits I ordered. I got a full refund but was told to keep the tap and dies rather than post them back. The fact I refused to pay the postage as I hadn’t ordered the tap and dies might have had some bearing on this. I doubt very much I could show them to my brother, a time served fitter and turner who worked up to a PhD in Engineering, without him collapsing in fits of laughter. But they might do for my small woodwork jobs where I need a custom bolt and bolt. This is an extremely interesting and educational film which might take more that one viewing. Thank you very much to all concerned.

History preserved! Thank you for your efforts!!

Love " jam handy " films .

Fantastic video. Thanks

I have a vintage set of tap and dies from WW2 made by Vermont tap and die,handed down from my father. They come in very handy from time to time. Still in business.

Unbelievable quality for its age

An excellent film. Many thanks.

"Facts about Taps and Tapping" is documented by the Jam Handy Production log records as being completed on September 5, 1952. It was registered for copyright on October 8, 1952. So the film was released in late 1952.

25:45 That part of South Railway St. in Regina is now called Saskatchewan Drive. Bowman brothers Aden and Irvin sold "wholesale auto parts, household appliances and machine shop services." They are long gone, and so is their Regina warehouse building, which was new in 1929. Aden Bowman was a civic minded man and a high school in Saskatoon Saskatchewan is named in his memory.

stunning photography awesome explanations

Such professional film!

This is beautiful!

Amazing, cant thank enough for the upload

Very interesting and fantastic engineering. shipping to all over the world as the last frames show South Africa, not South America. JHB is Johannesburg in South Africa and Natal is also in South Africa.

19:32 Noooooooo!!!! I wish I had these type of videos at school.

Great channel concept, a man after my own heart, Subscribed.

Great video. There are even more variations and technologies in these kind of cutting tools nowadays. Different steel alloys such as carbon steel and cobalt steel, etc. More surface treatment than were mentioned: titanium nitride (TiN), titanium carbonitride (TiCN) and others. Designs such as spiral point flutes too.

Wonderful, very interesting.

Just watched this for the nostalgia

The days when Apprentices were taught their Trades well, and they learned how to do the job correctly. Fast forward to today, s way of doing things, now apprentices are only taught enough to be responsible for cheap labour. They mostly finish their apprenticeship only know enough to do one job ??????? We always need to improve with time, but the way of teaching apprentices has gone backwards.

I Loved it!!!!

Oh my God I just found ur channel - where have u been all my life!?!?

I assume the Pacific Rim took over most of this work. At 20 I got my first set of taps and dies from the Snap On driver. Still have the whole set.

Nothing more beautiful than a tap in slow motion. I would've liked to see how the tap grooves are really made. Are they ground in with an extremely durable tool?

Interesting,in the UK we have Taper, Second and Plug - unless I've been doing it wrong for the last 14 years?!

I think after watching this video i may have a diploma in Tap & Die

Chromium treatment... gloves? Who needs gloves?

3:05 A Grade whale squeezings ^-^

The cutting fluid there looks like oil, but I'm not sure if plain old oil is used as frequently these days as specialized fluids. Anyone have any insight?

I would never be able to afford a set of these.

"I'd tap that"

Where ever possible and the I.D. is big enough, use a threading bar.

Tap and Die, Tool and Die, it's all so confusing!

25:44 but not Europe, as they can do very good themselves :--)

The graph @24:31 looks like a tap

Screws!! Buy some today, won't you?

Funny that germans had to create a word for a tap. It's made of two words and is called "Gewindeschneider"

Have an old timer who has a shop full of lathes brideports tig mig welder . There isn't anything he can't make . I call him the mad scientist, and he is reasonable with what he charges. Lost art I'm afraid no one to replace these old tool and die guys.

Greasy carcinogens all over my hand all day long

Greenfield? Never heard of them. The colonies... LOL Are those in gallons and inches? Pffffthahaha!
