In college, one of my lessons was for me to make a male and a female acme 2 TPI, I used a lathe dog to index it to a 4 jaw chuck and made a double start 4 TPI. My instructor was so impressed, he gathered the whole class and showed it off. It now resides in the display case at the college.
That is a great looking old lathe, I have cut a million acme threads and this is fun to watch but taking that long would never do in a modern shop. Love to have a lathe like that in good shape.
When it comes to the thread cutting and thread cutting only the cnc is not that much faster, But the over all turning of the part is much faster. There are also parts that a C.N.C. machine just can not handle. As per propeller shafts for rather large Aircraft Carriers. The Navy tried.
In Regards to that part and cutting the .5 pitch .5 lead acme tread you can not run it to fast with that high lead as it gets hard to control. I think they were also running it very slow to show on camera. Turning the other part of the part would be done quite faster with modern coated carbide tooling. Those old machines were cast iron frames, modern machines have a new product, a mix of epoxy and cement, it cures fast and does not need to normalize for 6 months before it can be machined. The cheaper modern machines have aluminum frames and are in no way as ridged as the others, but surely much better than nothing for the home machinist. Love to have one but no place to put it.
If the thread gauge nut is large enough to fit over the center of the tail stock, place it on there before the work piece and it will be ready to check the threads without removing the part from the lathe
The lathe is a Monarch. I don't know the model. I can identify it as a Monarch by the looking at the compound feed. Everybody noticed that he wasn't wearing safety glasses but also look at him using the file. He should be filing left handed when filing something on a lathe. When you file right handed on a lathe you will be wrapping your left arm around a spinning chuck. It's not much of a safety issue when using a small chuck or collets, but what are you going to do when using a 28 inch chuck or large face plate. If you are right handed you must train yourself to do it left handed on a lathe.
Which is probably why we have CNC Lathes now because it would fucking suck to have to train a part of your body that is not how your brain, and muscles, want to go. People are right handed by the vast majority so what were these machines made by the
Putting the cutting tool on the right hand side is probably safer for righties 99% of the time -- your right hand is on the side opposite from the chuck. You don't spend most of the time filing on the lathe.
On the last cut I would have picked up the speed some, maybe get a better finish providing you don't go into the chatter range or better get above it. But what do I know.? Only been doing it 40 years. Seen a lot of changes with carbides and formed cutters and increased speeds and surface finishes and CNC which are way faster reaction time than any human. I know of a fellow who cuts threads at the same speed you would normally turn material, 100 sfpm or above. His hand eye coordination and reaction time is amazing but he has been replaced by CNC and formed carbides that take you into 600 sfpm land. That said, I wish I had a solid machine such as demonstrated. There is no replacement for a brutally and beautiful heavy machine for taking heavy cuts and precision.
Norm, for us mortals without the hand/eye coordination Colchester lathes had an accessory called an Ainjest thread cutting attachment that allows threading at normal speeds to a shoulder. I'm sure it was also used on others.
@@charlieinsingapore Thank you for the tip. I Googled the Ainjest and found some info. Fascinating. If you are interested in such things [as we all are or we wouldn't be watching these videos], there is a vid about threading on a Hendey lathe and another about rebuilding a Hendey lathe which show some interesting features such as an interesting cross slide stop and reversing lead screw. Just amazing these genius old ideas have almost vanished.
" Before running the lathe, it should be cleaned and oiled", Too bad People don't do that stuff anymore. I think these hendey lathes, rivaled monarch lathes at this point in history. Both very nice machine's.
he said it should be oiled but once a month is fine machines get dirty if they're good lathes they take the beating i personally don't want to deal with rust
Rob Mackenzie So noticing the type of audio means I have a "problem" with it? Being that it's an American film as am I, I'd say your comment is a poor attempt at trolling. Good luck with that.
Chris Hax Sorry I hurt your feelings Bud. You should know that this film was made before stereo and be smart enough not to comment about it. Your syntax is also terrible. If I read what you said literally you are also an American film. No wonder your country is in such rough shape
Rob Mackenzie I should know that this film was made before stereo? Sorry, but most of the people that were around before stereo are not using a computer today(maybe you're an exception). I made a historical note which was educational to me. Can the same be said about you? No, negativity is all you spew. I'd be mad too living in the land of BBC and gems like "Doctor Who".
It seems that part of the skills then was not to get injured when working. This reminds me of a mechanical engineer who always wear white coveralls when working or inspecting work in the engine room of ships under repair in a dock yard and never once saw his clothes soiled
Not a machinist here -- I was wondering how the operator got that turned part off after pressing it into another part so tightly with an arbor press? Anyone know?
I was gonna mention how my right ear suffered from atrophy during this video, but I don't want to be chastised for being born with a silver spoon in my ear.

+1903A3shooter how much faster would a modern machinest be expected to cut one? And also whats different abouts todays lathes compared to these ones?
beyondthelol CNC lathes can do the same much faster.

You mean the modern shop where human is taken out of the equation. What a "machinist"
I'm on the same Hendey! I love this lathe and needed to know how to do an acme thread. can't wait to learn more
A 13 inch South Bend lathe is a beautiful machine!
A center height line on the tail stock.. what a great idea
As long as it doesn't rock.
Dude, That's Centuries old. machines of the 1800 already had it........
It's normal idea, dude.
Yes I noticed that, I'm new to lathe work so I will incorporate this on mine. Love that Lathe but I don't think it would fit in my shed, ha ha .
Just been to check and it already has it but so feint I missed it.
Это станки шедевры и мечта миллионов сегодняшних мужчин с руками не из жопы
"tail of the dog" "engaged worms" -- love these vividly weird machining terms!

It was a Hendey tool room lathe of 12" swing. They were some of the best lathes ever. Daniel

AtelierDBurgoyne it was a hendey!
No I don't think it's a Monarch. The gearbox is wrong as are the apron clutch handles

i love my hendey lathe I'm a very proud owner
We watched this same film in trade school 1989
i have wanted to cut an acme thread for years and never have but i will now thanks
I also a lathe machine work🙋♂️
Whenever I cut threads I turn the cutter upside down and run the lath in reverse thus avoiding the possibility of crashing into the spindle.

Hendy 12" lathe
he was a vintage machinist
i never turned a hollow part, but I thought it was called a Mandrel that you slid the part over - same thing as arbor, I guess.
That lathe is awesome , they dont make them like that anymore.
you're right
they make better machines lol
@@christophercolumbus8944better technology maybe, but not better quality……
You need a lathe to make a lathe so you need a chicken to make an egg... paradox resolved
We don't need any stinking safety glasses!
Guessing this was before stereo sound became widely used.

It's a Hendey!
best oil for cutting machine
Not a machinist here -- I was wondering how the operator got that turned part off after pressing it into another part so tightly with an arbor press? Anyone know?
It looks like the part was bored all the way through. The arbor appears to be sticking out of both ends, so it can be pressed back out.
The arbor has a slight taper of one or two thousandths and is pressed off the opposite direction of assembly.
tkarlmann t
Use an arbor press and press the arbor out from the opposite direction.
Old movie good
A lazer in the tail stock ?!!!
Hendey 12x30
do people still use lathes like this today?
+beyondthelol
Manual lathes like this are continuously in use today.
yes. everyday
yes but with better cutting tools
A tie, long sleeves and no glasses...not like that today.
every day
in pakistan
Plunge cuts,interesting...
waw
I hate that this man is called an "Operator"... This man is/ was a Machinist...
totally underrated. Are you sure a commercial pilot skill level is higher than a man that can fully operate this lathe?
Cutting ACME is fun. It's kinda too bad the stuff you get from McMaster is so much better than the home machinist can do on a lathe.
...McMaster....most of their stuff has rolled threads....
I'm no expert, but isn't rolled and ground a better product than cut?
Andrew Tubbiolo These days...rolled threads are very accurate, and stronger due to being cold-worked....along with good surface finish...
Home machinist rarely can do something really good, tbh.
have you cut trapezoidal threads?
any difference?
Well I'll be damned ..... looks like my Hendey lathe.

Old school was real slow. And I've watched old videos that operators don't wear any safety glasses.
hes going slow for film purposes , the old timers could get a move on
