    Nice work. Six years on I hope this guy is still around and enjoying working metal, or at least has found a comfy chair near good friends. :-)A minor quibble: the description he gives for cavitation is actually "ventilation" - the prop sucking air down from the surface (so yeah, the "cavitation plate" on an outboard is there to reduce ventilation).Cavitation can occur on any propeller and is caused when the forward side of the blade (called the "back" because you're usually looking at it from behind the boat) pulls so hard on the water that the pressure drop vaporizes the water into bubbles (which can erode the metal of the blade when they collapse) or sheets (usually not as damaging).Also, in larger propellers the convex curve over the back of the blade does most of the work of pulling the boat forward. Blades have a foil shaped into their thickness (they're spinning wings, really), so grinding the back flat can reduce the amount of thrust generated by that part of the blade just like a small reduction in pitch would, and this too can produce vibration.Cupping the trailing edge of the blade is much like extending the flaps on an airplane wing: it increases the effective camber of the blade's foil shape and allows it to produce more thrust for a given overall pitch angle. Cupping does disturb the flow over the blade when going in reverse, often with a noticable loss of thrust.

    I hope a boat is not trying to break any "Land speed records"

    It's a tough business, because it's a skill and it should be very valuable, but unless it's very special prop you are so limited to how much time you can put into it.

    I did that kind of work for 16 years. In Settle (Ballard). I could do it. I'd like to work with props again. I'll be Free in 3.5 years or so........

    Good video of probably what will soon be a lost art, in this age of throw away stuff and buy another piece of non repairable junk.

      I used to recondition my props, but it cost more to recondition one then to buy one. I can recondition for $75 or buy new for $50. You are absolutely correct though... a lost skill. I boat in the east coast intercoastal waterways and constantly chew through props. At least one a season. Always aluminum and I keep a spare stainless steel prop stashed onboard.

    Please show the prop when describing what you’re talking about. Don’t need to watch you talk.

    I'm not sure if the guys in this video are misogynists themselves, or if they're making fun of men who can't own up to their own mistakes and instead are cowards and blame it on their wives/girlfriends...

    • @Kogacarlo
      @Kogacarlo 10 ปีที่แล้ว +2

      They are making fun of men.

    Telling on other men... GOOD MAN CODE ... SPOS.... Probably his own shit. What does it matter who did it?

    I turned off your video when you blame all the dings on women.

    • @Patriot-up2td
      @Patriot-up2td 7 ปีที่แล้ว +2

      Christine Bradstreet actually he didn't blame all the dings on woman, he was saying all the "too proud to admit it men" blamed it on the woman. He was being witty and actually putting the blame back on the men who did it. It's a good video, you should watch it...

    • @CootShooter
      @CootShooter 7 ปีที่แล้ว

      Jeez... take the joke... Is understanding sarcasm that dead nowadays? It is a ding on the men, not the woman.

    • @victorcastle1840
      @victorcastle1840 7 ปีที่แล้ว +7

      Now that is just like a woman, didn't listen, only heard part of what was said, and turned her brain off. Can't blame a man for that !

    • @alibragge1986
      @alibragge1986 7 ปีที่แล้ว

      Christine Bradstreet it's a tongue in cheek poke at the men who blame their wives and or girlfriends. Not a dig at women in general.

    • @physicsguybrian

      It's over-reaction like yours that give the female gender bad representation. You comment like you are taking a stand for women but you are only perpetuating stereotype.
