Nice mill, vbm , I did an apprenticeship in the 70s . The vbm I had to use was line shaft driven from the 1880 90s . Man she could still turn out great parts . I did work for a steel mill in Pennsylvania. Bearing blocks , roller shafts much more. Heavy work but I'm so happy to have done it.
Maybe I'm nostalgic, but it seems instructional films were more professional back then. I see stuff now that tries too hard to be funny rather than explain or properly show things.
The best things about machine tools in the 1940s and 1930s is that every instruments such as monitors, sensors, indicators, effectors, feedback systems, etc ARE ALL 100% ANALOG-BASED SERVO-MECHANISMS that shows everything simultaneously regardless whether you want to see them or not. And in the late 1970s and early 1980s they started using an all analog fiber optical technology based instruments combined with an all analog fresnel lens optical vision enhancers with fiber optic cable directed incandescent light bulb(s) to provide clear lighting and to measure, monitor, sensor, to provide feedback with precision ranging from 10 millionth of an inch to 11 millionth inch. With such machine tools YOU CAN LEARN EVERYTHING AND NOT DEPENDENT ON FRAGILE SILICON IC CHIPS THAT CAN RENDER ALL OF YOUR MACHINES INTO USELESS SCRAP JUNK!

Did you know its not uncommon for some shops today to be using the same machines as in this film. Repair/rebuilding shops are a good example. It just doesn't pay to buy a new machine to make a key-way in a shaft once in a while.

Fractions? No way.
@@geocam2 Imperial units are, nowadays, defined in terms of metric units, but they owe their origins to far more obscure and ancient measurement standards.
One thing that they barely mentioned was machining direction. You CANNOT climb mill on these old horizontal mills because of the way their lead screw was designed. If you did decide to climb mill, the slack in the lead screw would cause it to feed way too much into the material, likely causing your workpiece to get thrown across the shop. Climb milling isn’t a problem now since new machines have ball screws.
Doesn't matter, old machines used ball screws. That only happens if you take too big of a cut per tooth. CNC machine does it too, you'll get a servo x axis alarm though. Or the spindle stalls.
Bro, I climb mill all the time with a conventional lead screw. Taking a reasonable size cut. Also you need to get the slack out screw first then cut. You just need to use your judgement.
Yes. The Metric system was created as a result of understanding that an interrelated and base 10 system of measurement is preferred. This concept of measurement might not have been developed if earlier systems of measurement hadn't first been attempted. I hope these films are appreciated as being part of the historic record. We are not advocating that things get done exactly the same way today. Technology properly evolves through time.
There may be some truth to that statement. BUT, when we started going metric back in the 80's and 90's EVERYTHING went to hell! Our machines, cars , tractors, trucks and and tools are garbage compared to the earlier versions, with a very few exceptions!!
@Museum Metric is based on "the power of 10" makes understanding easy. Metric is also more accurate, increments are smaller. Metric also perfectly translates into volume and mass. If an objects density is less than 1g per cm3 it will float on water. Metric threads are also better. Programming is way easier in metric cause your using whole numbers, no fractions. ie 12mm tool has 6 mm radius. A 5/32" tool has what radius? You have a 1000 mm you can say that's 1 m. But if you have 150" inches you say 12 ft 6 in and sometimes a fraction. Inch fractions don't translate into ft. List goes on why metric is far superior
@@trikebum5 Interestingly, the reason the Reagan era push toward adoption of the metricsystem failed was that the machinist union, among others, believed that the move would facilitate the decline of American manufacturing by allowing foreign machine parts into the Country. Unfortunately, the unions failed to understand that by abandoning the metric system "change over" the unions were signing their own death warrant by crippling US expansion into forign markets. Basically the unions failed to understand that it was much less expensive for foreign interests to retool for the US market and it would be for the US to retool for the foreign market. And in the end we just ended up buying the whole product from overseas. This in turn helped create to some measurable degree the disposable world that we live in now. To be sure, this is not the only mistake but the unions made. But I think it was the largest mistake, with the most far reaching consiquences. My father grandfather and stepfather were all Machinist oh, I'm a history major. So it's easy for me to judge. But as I'm old enough to remember the transition, I feel comfortable saying no one other than the economist could have predicted the consequence.
Take a look at the Millers Falls Tool Co. film. The guy sticks his hand into the wood cutting lathe while it cuts tool handles! I am sure accidents happened, but apprenticeships and hands-on training was common, in those days. Part of what you were taught was how to avoid killing yourself. That generation may have injured itself less frequently than the modern one would in the same circumstances.
Working people of that time may have been even more aware and cautious of the risks. I survived working with high voltage vacuum tube equipment. Try finding anything over 12 volts, these days.
An end mill would create a stress point because there is no natural chamfer when the keyway ends and thus cracks are bound to start there. The keyway cutter creates a gentle slope as it cuts and thus no crack-inducing stress points will form.
Just think, if you used metric, all the numbers used would be zeros instead of 15 thousandths or, .001678 or .001456739 etc., plus all the multiplying and dividing of multi-numeral equations. For example: 20x6.283"=125.664"=10.472 ft. per min. for just one measurement. Whew!
R U 1 2 The only way that the numbers would end in zeros is if accuracy was not important. His answer, 1.171 inches comes out to 29.743 mm. Still a fraction.
axisfiver axisfiver Try climb milling on a conventional machine. You will find out what what the term crash means. Conventional machines use standard Acme threaded lead screws. These screws have backlash. If you were to climb mill, the force of the cut would take up the backlash violently.

Not in the real world. Repair and custom machining work often use the same vintage tools you see in the video. Repair machining is what keeps factories going. It's faster to cut metal for individual parts if their complexity doesn't require CNC than it is to program and set up CNC machining centers. My machine shop owner bro (I help sort out older CNC machines and his computers) is a multi-millionaire and most of his fleet is ancient. He even has a near-perfect Cincinnati shaper older than 1920. He has CNC too but manual machines are critical to making money. No CNC of similar capacity to his WWII American Pacemaker lathes would pay off in custom and repair machining.

Those machines still run to this day. Solid. But I am a CnC machinist. I would rather put that in my hurco. I could one shot that key way on size in about 15 seconds in cutter comp. yes those machines helped win the war. There is just no place in the modern machine shop. It would be impossible to turn a profit. Pun intended.
Do you still check the work? Much of the content of these films are about stressing that the job gets done right. Of course technology improves over time, but I still don't see how humans will no longer need to verify that things are being done properly.
