 This is the propeller blades. I've been using on my boat. Yeah, I took it apart First I made these blades a little bigger than I thought they should be and then trim them down to the point where I thought they were a little bit too small so I could figure the size should be just a little bit bigger than that and I was hammering them a lot getting them into the right kind of shape and Once I was satisfied with them I decided to make some really good copies because you know with all the hammering and bending on this they don't come out Super smooth, you know, they're smooth-ish, but definitely not super smooth. So then I took the blades off And pulled out a piece of curvy pipe I've been saving Because the propeller blades it's kind of nice to have a curve one way this way But then the opposite way this way, you know like a saddle curve and an inside curve of a pipe does that so I Layed this on here figured out where it matched the closest Drew my blade a little bit bigger or actually a little longer in the same same width Cut it out and then I got three blades That I didn't have to curve so because I didn't curve them the curve is really even and there's no dense or anything so this should be Pretty much an optimized propeller for the boat Hoping pretty close. Anyway. Oh before I made this one. I also did some calculations. See that calculations to You know check that my propeller blades are at least theoretically about right and they they seem pretty good based on the Calculations I did increase the pitch just a little bit based on the calculations Because according to my calculations my old propeller was limiting my speed at about nine miles per hour And I got up to maybe a little bit more than that and I got up to eight point nine miles per hour So that's pretty good. So I made this one so it'll hopefully go more like tennis I've used up all my internal curves pipes So hopefully I got it. Oh look at that So smooth I did have to buff the inside because that pipe was an exhaust pipe So the outer curve Was a very shiny and polished, but the inside was pretty rough If you want to see all the details of how this is fit together just go back a few videos to where I made one What's a good looking propeller hope it works as good as it looks Well that way sounds like it's balanced a lot better than the last one kind of want to take the boat out I don't know about the weather though. I had to pee off this boat. I just put one foot there and one foot here Ah should be no problem. I could put half my weight on that Or I could stand right on the front pee off the side. Oh, maybe I'll do that. That sounds kind of fun You know, I will need to be able to get up to the roof To deploy my solar covers and undo them when I'm out in the water. So I should test this Now I'm gonna go. Okay. Bye. I think before I go in I'm gonna get some exercise all right 10 laps around the bay pedals only alternating between legs and arms all right Looks like a good spot to start. All right. Jamie. What are you doing here? So this gear here fits in here and it presses against this gear And it's pushed against the gear with this rubber wheel Now the rubber wheel was pushing against You know this round pipe And there wasn't that much surface area for it to really push on And once in a while if I was pedaling hard it would skip a gear Make a terrible sound didn't get damaged because the material is really strong I would like to fix that though. So I'm putting this flat plate along the back I'm not sure if it's thick enough. It might end up just getting bent over time. Still It'll give a better surface for the wheel to press against this wheel to press against then Just that pipe I cut this out of an old toaster oven I put a bit of oil on there too That should help I didn't put oil on it at the beginning because I wanted the teeth to wear into each other And these are way smoother than when I made it It looks like that worked There's a pipe inside that gets smashed in there And it presses against the tabs at the bottom of these that are folded up And it holds it locks it all together. So when I smashed that pipe in It bent these propeller blades back further than I wanted them to be I was hoping it wouldn't really matter So I just tried it Now I'm thinking maybe that mattered more than I was hoping so I took my vise grapes and cranked them forward bent them I didn't want to do that because I don't want to loosen them but they still seem Like they're in there tight. So I think it'll be all right Let's see if that makes any difference here All right, let's give that stuff a try All right pedals don't skip All right, let's see if that propeller made any difference does feel better. Oh, that feels a lot better Can you tell me if this is any faster or slower or what than yesterday?
