He was special. ☺️❤️

[@avflyguy]

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.

No it is build from steel and painted yellow.

[@terencecottington4273]

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.

[@pouyan225]

I always enjoy Culver Prop videos. Please always keep in mind that long hair and rotating machinery can be a deadly combination. Best regards.........

[@plywoodcarjohnson5412]

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!

[@CulverProps]

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

[@karitane]

[@RosaStringWorks]

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 KZbin. 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.

[@tim_bbq1008]

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!

[@CulverProps]

Good point! I will add that in on a video. It is the exact size and I can adjust the lathe to cut thicker or thinner or exact to the template

[@andrewmacomber1638]

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

[@stuarthossack7906]

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?

I am still learning, everyday. New patterns, new engine and plane combinations and their performances. It’s a lot about learning airframes and engines

[@stuarthossack7906]

@@CulverProps so math, science and engineering to a great degree? So this is not just artisan, it's "proper engineering"? -we just see the manual labour not the cerebral stuff? 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.

I noticed that you only use four pieces of wood versus other wood prop makers, where they use maybe 15 thin pieces to make their prop. Would you be so kind to explain the difference between those two designs. I enjoy your videos very much and I know you miss your grandfather. He taught you a great skill.

[@CulverProps]

Thank you, and yes i do! There is strength in layers, so i understand why some of the other prop makers do that. 4 layers are plenty strong, so we prefer more wood than glue. This is how Mr. Culver made them and it has proved to be very successful.

[@bradmoyer9737]

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 ____

[@larrykeenan598]

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.

[@CulverProps]

Lol! Yes they are a conversion

They have proven well with the aircraft market. I make a ton of them!

Aby odwzorowanie było idealne frez tarczowy musi być tej samej średnicy co tarcza prowadząca po wzorniku śmigła. Czy jeżeli ostrzysz frez tarczowy i zmniejsza się jego średnica to również zmniejszasz średnicę tarczy prowadzącej , albo ją zostawiasz taką samą zmieniając tylko frez tarczowy na nowy ? Pozdrowienia z Polski , Wiechu . For perfect reproduction, the disc cutter must be the same diameter as the disc guiding the propeller template. If you sharpen a disc milling cutter and its diameter decreases, do you also reduce the diameter of the guide disc, or leave it the same and just replace the disc milling cutter with a new one?

I can adjust and recalibrate when I put on new blades

[@musicalal3752]

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?

[@CulverProps]

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

[@CulverProps]

[@scotte2815]

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.

[@lrstaf6]

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]

This is something the owners made

[@LTVoyager]

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. 😁

[@CulverProps]

Interesting theory.

[@rodrigosenareli4114]

very very good

[@robertbolding4182]

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.

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. Again the simplistic explanations you give are refreshing in today's day and age. I am not very tech-minded though I do understand its advantages in some things. I did watch the the video in various stages and was very impressed by the simplicity yet precision of your duplicating lathe. Absolutely fascinating to me.
