I think what is so amazing is the lathe is for the most part build from wood. No computers, lasers, highly machined CNC equipment anywhere. Just good ole fashioned 'this is how grandpa taught me how to do it'. Truly a gift and sadly, will someday be a lost art. Keep the shop going. How cool would it be to see it still churning out props 50 years from now.
Nice Shirt you're wearing. I grew up near there. They have a great selection of wood including exotic overseas type. Overall a really cool hardware store.
I am making a decorative prop using chainsaw and anglegrinder. I must admit i had no IDEA how thin prop blades are. They look so thick! My prop looks like it was stolen from a cartoon. Also I thought the twist was the driving force, carving through the air. In reality the blade is an aeroplane wing. Gheez!!! The twist is the most obvious, but matters the least. I guess in theory a prop would work without any twist. Anyway! Great upload!
They are a unique experience to build lol. The angle of the blade is put into a calculation and it gives you inches of pitch. So a prop may be 60” in diameter and have 26” of pitch. That means for every single rotation of the prop the plane moves 26” forward
I love this channel. It's very nice to see what goes on during manufacturing process of Propellers. I also highly admire your honesty and straightforwardness. Thanks!
You say that people often want or expect more technical detail when you explain the way in which you make these beautiful props and you say the process is fairly straight forward but looking at your videos I think I can comfortably say that most people would not have a clue how or where to begin and I include myself here as well. My point being is that actually there is a lot of science which includes but is not limited to Math, Physics, Chemistry, Meteorology & Engineering Atmospheric Sciences. All these you use whilst constructing these props. I thank gifted people like and thank you for sharing your trade. Looking forward to the next one.
Hi Alaina and Katrina, Always enjoy watching your videos. It is relaxing watching the lathe go round and round. Hi to Grandma and you and Katrina and the family stay safe.
That is pretty cool like you said about slow-mo'ing the drill press. We really enjoy your videos. Thank you. p.s. Thank you for the real time lathe work.
That lathe is very cool. Never seen anything quite like that. Was wondering how you made repeated odd surfaces like the air foil surface. Thanks again for walking us through it.
Hi there, I love that the process just isn't that scientific, I don't make any thing so cool as propellers but I relate to how you work ☺ thank you for sharing your work
Alaina, you might want to look into a Digital Read Out for your mill. Commonly called a DRO. This is a highly accurate way to drill the center hole, as well as any bolt hole circle that you need to drill. You can program into the DRO any size pattern for any size prop. Then you just move the table of the mill to the exact location to drill the holes. Believe it or not, much more accurate that using a pattern. DROs are not all that expensive especially considering how much value they provide. I would be glad to help you sort that out if you are interested in pursuing it. Search Milling Machine Bolt Hole Circle DRO on RUclips. Tons of info on them. Jerry
Very interesting. We use wood props on wild rice pickers. They are six ft. props fastened on the fly wheel of a Chevy 350 V-8. I refinished one prop two summers ago. Light sanding with steel wool and a couple of coats of solvent based varnish. Don’t remember the manufacture of the props.
That funny because I just had it replaced. It was hard to get it to draft and I smoked myself out every morning and Monday I snapped. The guys had a new one in within 2 hours. Lol
You commenters had better jump in quick because when she reaches a million subscribers you will not get the heart reply she will be overwhelmed but I know her appreciation will be a given.
Hey Alaina, what about “video angles” I have no complaints it looks very nice, by the way, you are a props engineer not a videomaker, so keep on doing things as you are doing now, you rock ma’am. Greetz.
@@CulverProps you deserve it, if you can find the time to make props and video’s to entertain us and let us enjoy your craftswomenship you are my hero.
At approximately 12:00 you discuss making 'pitch adjustments'. Perhaps on another video you explain what that means, why it is needed, and how the adjustment is made? Also, is the template propeller the exact size of the final product, or is it slightly bigger to allow for sanding and balancing? Or does the lathe have an adjustment to allow for sanding and balancing? Love the videos, keep up the interesting youtubes!
With regard to the lathe, what diameter are the blades and how many hours of service do they run before they need to be resharpened or replaced? Do you do your own resharpening?
10” and 10 tooth. I use them until I can see that they aren’t cutting correctly, it all has to do with how long the props are, what material they are, if I hit a nail.....just a lot of variables. I send them off
So I asked you before what youd charge for a corvair prop but I dont know if I mentioned it was a pusher prop for a boat..🤔 If i brought you an old one that I have thats too weatherd to use could you use that for a patern to make me one like it???😁😁 please 😁😁 lol Love youre videos.

Do you think you are still learning? - if so, what is it that's improving? the fine detail and nuances like a violin maker? efficient use of time? do your blades "get better"? or is it just a prescribed mechanical process?

Any chance you could let us look over your shoulder from start to finish on a new project? From calculator to flying the prop? A big ask but the whole context would be fascinating, for me at least. Great vid again.
This was very interesting. I've always wondered how the props are made. Are your props FAA/PMA certified, or are they strictly made for experimental aircraft?
I think i will never carve a prop for sale but I have another product in mind for a machine with a carver much like the one you use . i might not make much money from it but because i won't be buying the product and can get free wood from a tree, i own acres of forest it will save me about 15,000 a year.
Probably a stupid question but when you are describing a “Corvair” engine, are referring to an automotive engine converted to general aviation standards? I’m from a generation that remembers Ralph Naders war on “Corvair” cars as unsafe pieces of ____
Nader's problem was the engine, battery, and front gas tank placement. I had a Corvair and Sears would sell me a battery but wouldn't install it. The 6 cylinder, horizontally opposed engine ran well. There were problems with the pushrod tube seals leaking oil but all in all, it was a good running air-cooled engine.
Hi; Is your lathe a unit that was designed by the original owner of the shop, or is it available from some manufacturer? If it's some manufacturer, what is the name of that manufacturer. Also I am intersted to know at what rpm does it turn? I was a machinery designer before retirement, and these things always interest me.
@@CulverProps I didn't think it was too too old. I was thinking maybe the 80s. How cool. Your videos are all over my recommended. I guess I'm going to learn all about making props next 🤣
I'm not surprised that there is not a lot of math involved. The thing about making a product like this is once you work out the profile/shape/geometry and then the process of how it goes together it becomes a very simple thing to repeat. There is math and science there but it isn't needed once you have a set up like you have. If somebody wanted to see math at work in making a prop they can go to see how a HUGE composite constant speed prop on a large turbine powered plane.
Some additional detail on tractor vs. pusher. You mentioned the engine being in front of the pilot vs. behind, but that is not a definition of tractor or pusher that I am aware of. There are two generally accepted definitions: on related to the prop and the other to the airframe. A tractor prop is one that is in front of the engine and thus pulling on the crankshaft (tension). A pusher prop is one behind the engine and thus pushes on the crankshaft placing it in compression. On the other hand, a tractor airplane has the thrust in front of the center of gravity and a pusher has the thrust behind the CoG. So, you could have pusher props on an airplane that was in a tractor configuration if the engines were far enough forward yet had props on the back that push on the crank. 😁
You mean you actually drop things and have hard time finding them? Going to have to un subscribe lol. I thought I was the only one that does that and it's usually the one particular nut or bolt on the airplane that you only have one of and it's special. I swear I can watch where it lands and go to pick it up and that bugger has moved somewhere. Also, I appreciate your comments about things are not as technical as a lot of people would like them to be. Most of Aviation with the exception of recently the new computerized software, has been eyeball engineering and even then whether the tech minded realize it or not they are still eyeball engineering them because it has to be aesthetically appealing as well as safe and functional. An airplane is a series of compromises that end up meshing well to perform to the best of the design's ability in all realms of flight with the exception of specialized aircraft and even then there are compromises in performance. Propellers are no different. I'm a big fan of wooden propellers. They absorb shock and are less apt to cause catastrophic failure should a blade begin to separate. They're not as efficient as a carbon fiber or metal but they are much more forgiving and have that classic look that just cannot be beat.

Is there such a thing as a 3 or 4 bladed prop made of wood? I imagine wood blades joined/mounted to a steel/aluminum hub. ❤️✌️
Yes, back in WW1
