Greenfield Tap & Die - Facts About Taps and Tapping

[@Coffieman5150]

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.

[@MuseumofOurIndustrialHeritage]

Send me some to digitize!! I'm running out. How many were ever made, how many survive, and where do I find them??

[@jimsvideos7201]

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

[@TheArsonsmith4242]

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

[@peteryeung111]

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

[@Johnnycdrums]

Same good quality.

[@charlienewman9824]

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 !

[@joandar1]

Charlie Newman, those words echo my Fathers words. he used to say if I knew half of what my Father had forgot I would be a smart man. To an extent I agree, I will only add that I have learned new things that both of these great men would not know. I still do things the way my Grandfather used to do things, however I do some things that they would not know of as time and tech moves on. It is important though to not loose sight of our heritage. So I look at as much of the old ways as I can as there is always something we can learn and should there be a global disaster then I don't think Tech will save us, the basics may. Cheers from John, Australia.

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.

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.

[@yannkitson116]

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.

[@pco1984]

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

[@larrysnyder3475]

Fantastic video. Thanks

[@mumiemonstret]

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.

[@MuseumofOurIndustrialHeritage]

If memory serves, the Jam Handy was a 1904 Olympiad and formed the JHO around 1912. They became masters of educational and promotional films. Much of their work was for General Motors. They were rather late in getting into color, and this film was shot around 1952. Many recognizable film industry names worked at one time or another for them.

[@jimsvideos7201]

That shot was a highlight, which is a feat in this film.

[@markharris5771]

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.

An excellent film. Many thanks.

Thanks to the talents of the Jam Handy Organization

[@lifuranph.d.9440]

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.

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.

[@alfredoeduardo1974]

Such professional film!

[@detectorguy]

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

[@LukasDubeda]

This is beautiful!

[@Dog.soldier1950]

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.

[@mattn5594]

Unbelievable quality for its age

[@thorsbyguy5121]

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.

"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.

[@Tadesan]

Jonathan Boschen aww jam handy

[@godfreypoon5148]

Fun fact: They make industrial equipment now. I've seen their logo on several pieces of machinery.

[@RichardFallstich]

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.

[@Gottenhimfella]

I was intrigued that they mentioned serial taps. 11:22 They are almost unknown in the US today, but commonly available (for all threadforms, not just trapezoidal) in Europe and the (British) Commonwealth. Great for tough materials, especially high nickel alloys.

[@russelloneill9763]

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.

[@daveh777]

I Loved it!!!!

[@MrSaemichlaus]

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?

[@Salverstein]

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

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

[@MegaRiffraff]

J P we have them here as well.

[@jockellis]

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.

[@RichardFallstich]

There is still Greenfield Industries (Cleveland, Chicago-Latrobe, Cle-Line, Cle-Force, Bassett, Vermont Tap & Die) manufacturing in South Carolina. Kennametal announced $5 million and 70-job expansion in Greenfield continuing Greenfield Tap & Die legacy in Massachusetts.

[@catsupchutney]

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?

[@Johnnycdrums]

It's not plain old oil, it's cutting oil, of which their are all kinds of gradations and manufactures. For tapping, the lubrication of cutting oil is better than water soluble based coolants. I've run tapping heads on CNC lathes and mills using water soluble coolant, but only because it was one of many tools on the same set up, and oil can't stand up as a coolant considering the high speeds of the other tooling.

[@shawnbottom4769]

Well there’s not really a such thing as “plain old oil” and I actually cringe at the parts where people are dousing their hands in the stuff. Back then they put additives in cutting fluids that it turned out were really bad for humans. But those oils performed supremely. I often used thread forming taps which weren’t covered here. Usually I would brush some way oil as the tap was going in. Worked great and the coolant used for other tools would get contaminated with way oil anyway and that could be skimmed off later.

[@weldmachine]

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.

[@MuseumofOurIndustrialHeritage]

Thank you for the comment. You touched on one point I was trying to make. I love technology. The potential for invention and productivity has never been greater in history. However, I think it is a grave mistake to expect machines to think for us or become a replacement for human accuracy and creativity!

[@randymurray934]

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

[@tylerkrug7719]

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

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!

[@rustyaxelrod]

camgere - Also GO - NOT GO. The tools I use in my job are labeled GO - NO GO.

[@MuseumofOurIndustrialHeritage]

Those tools are probably for quality control. The allow spot checking on the production line to see if the parts are within allowed specifications. Very important! We have some film hidden away which shows some of this.

[@Gottenhimfella]

Made more confusing by the US making the spelling of micrometre the same as micrometer.

[@ShikamaruXT]

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

[@pitu72ger]

ShikamaruXT it's common practice in German

[@Exgrmbl]

+ShikamaruXT Makes more sense. Thread-cutter is much more descriptive than "tap". If you have the words you might as well use them. So it is not really creating new words, just using and combining those you already have.

[@Exgrmbl]

+Notus Notus Aussengewindeschneider, literally external thread cutter.
