@@hw97karbine No kidding. The multiple/framed sets of grinders(?), both automated and hand-guided was kind of neat to watch. Somebody really thought about the best ways to kick up mass-production. They must have had SO many hand accidents, though.
yes and no. The negative of the film is much bigger than that of the sensor of the cellphone camera; shrink the negative to that size of the sensor and youd get an abysmal grainy image
We of a certain generation have grown up with digitization of old film in its infancy and the impression that the film itself was bad quality, in fact it was the digital technology that needed to catch up.
Just wow. Thank you for such amazing footage. Knew that the wooden props were laminated, becasue that's the strongest way to build them, but have never seen the actual assembly before. Those are some big propellers they're making there, but the precision, and the intense manual work involved, is incredible. Just watching them plane down those props, and the different machinery involved, in the whole process. Stunning. Kudos to the skill of those guys!
The fact that that massive propeller was so finely balanced that you could move it just by blowing on it is a testament to the workmanship, but really when you think about it they couldn't have made it of any lesser quality because the aircraft would simply shake itself to pieces.
Amazing how rapidly technology was advancing then. Just 15 years prior, the Wright Brothers hadn't made their first successful powered flight. Yet here we see how advanced the production of aircraft propellers had become. The construction, shape and airfoil theory was already well developed to a point still largely used today in light recreational aircraft over 100 years later.
Another interesting find, thank you! You don't think biplanes as being complex to assemble with modern hindsight, then you see the kinds of tools they had to work with and it was approaching F15 levels of construction for 1915...
Another great find. Wonder if these guys knew how lucky they were to be doing this job, rather than the alternative at that time. Having a trade saved them from being thrown in the meat grinder.
I never gave it much thought, but after watching the production it make sense. Others have pointed out many reasons why this is better. Another is natural wood has so many variations, the amount of props that would fail catastrophically, or even fail an inspection after complete, would be quite large.
Very interesting to see how the propellers are basically carved by hand. Such good craftsmanship.
There was a lot of manual finishing but you can also appreciate how much effort was saved by machinery when it came to getting the rough shape.

There are videos on YT of a contemporary small shop in the US still making them this way by hand with very similar tooling.
That camera quality is insanely impressive! Much better than modern phones😂

Manual machining just blows me away, these people were expert builders.

Cool shit. Amazing how skilled the work used to be.
Superb craftsmanship, all done by hand. Impressive.
Not all. It shows a bunch of different fabrication techniques, from manually shaping, to the various milling machines.
@@obsidianjane4413, Milling machines that are operated by men, not CNC. Don't be a nit-picking @zzhole!
Back then they might have known less than we do now, but they sure as hell were just as clever.
Giving props to everyone since 1917
That quality control is better than Boeing's.

Some of the power tools and workshop "safety methods" could be literal meat grinders of their own.
@@drott150 Yeah, that was my thought too. lol
Fascinating
seeing people without saftey googles and saftey equiment. Those were the days.
always thought they were made out of one piece of wood
Composites/plywood are always more flexible/sturdy, and you'd want that.
@@MM22966 wouldnt the prop eventually fall apart at the seam where it got glued due to stress and weather?
a solid piece would warp/twist over time. it's also not as strong as multiple plys of wood with grain running opposite
@@Keckegenkai no... they sealed the wood with multiple coats of varnish/shellac
