 This is the propeller for my zombie chopper the current one. I mean I've made several This one is really good Except I think it's a little bit too high pitch as in the propeller blades are tilted too far this way now just a quick little overview on pitch if your if your propeller blades were aimed directly this way and they were spinning around All they would do is mix the water spinning around right? But if they're turned this way all they would do is like slicing through the water Not really doing much of anything, but they'd be really easy to turn right and Now somewhere between this angle and that angle is like the optimum angle for your Motor your boat and everything and I think this is a little bit too steep. I Wanted to go back a little bit so It's rainy day today. Well the Sun's out now, but everything's soaking out. So I think I'm gonna make a new propeller New total propeller start with the mold This is the mold. It's just a bunch of blocks of wood glued together in a spiral shape Yeah, so this is the mold that I used to make these Propeller blades. You can actually see the outline of where I put the fiberglass on here So it kind of came off there, right? So I want to make another one of these And have each piece of wood each piece of wood thinner So that it ends up being more shallow slope up Oh back here. I have a bunch of wood. I cut on my lumber mill and yes Well, that's definitely thinner What why is Lego over here? somebody's in trouble Put the comb back on this part as a piece of PVC pipe Inside the same thickness as this and that fits on the pipe on the boat So I basically want these to be wrapped around so I could You know put these against this When I make the fiberglass piece will be stuck right on Hopefully that's held steady enough. This is the closest I've got to the right size. Oh, yeah. Oh, that looks great Pretty good Definitely a more shallow angle than that one. I guess I'll do some kind of measurement like from this corner to here And make sure they're the same going on what actually I think I Want it to be a little steeper at the bottom And shallower angle as it goes up because it'll be accelerating the water as it goes, you know Supposedly I'll just change that a little bit So I'll start with maybe And all three centimeters here Add a millimeter on everyone That sounds great No, maybe four centimeters. There's maybe four centimeters down here and I'll add a Senate one millimeter To the angle of everyone Sounds good. Oh, wow time to get some more glue Think I can get enough out of there Okay, now that I'm about to start gluing things. I need to get real serious about these measurements Okay, this one There's only like three point two millimeters And my new pieces of wood are much thinner so I might be going too low pitch. So maybe I want to make this one like Three and a half Yeah, I think like three and a half And I want to go too low pitch because I'll defeat the point of doing I could do math to figure it out, but I think I have a pretty good idea of what Okay I'm gonna leave that for a few hours Maybe something else. Maybe this won't move Okay, someone's gonna ask why do you make this corkscrewy shape like this, you know thing Instead of just having a propeller blade that's like this, right? It's the flat thing Okay, it can't just be a flat thing because the distance the propeller blade travels on the outside is Much further than the distance that travels on the inside, right? So this is just only traveling this far and out here it's traveling that far and When this travels this far and that travels that far they have to travel the same distance Through the water Get it. So it's got to be the same thickness Obviously this can't be all steps so I'm gonna use a What's this called an aluminium flap wheel flap disc, whatever smooth it out But you guys back up this is gonna be loud. I also don't want to get dusty On the piece of 60 grit sandpaper on the ground the other day It's visiting somewhere. Oh, it's still got some use in it. That's great This is wax Nothing will stick to this Small can and a big can of wax. This is car wax. It's not as good This stuff is very good at not letting fiberglass stick It also makes the wood look so nice doesn't it? Lay it on a little thick to fill in some of the creases But it's not perfect Okay, you want to know how this thing works Okay, this is the piece. It's attaching to make sure don't get wax on it Let's do go like this And I'll put a piece of fiberglass in the shape of the propeller right there attached to this and then I'll rotate this 360 divided by three 120 degrees and Then make another one and then rotate again and then make another one Three three propellers. I think I'll make it pretty much like this one Oh, yeah, and then this will stick out the back have any scientific way that I'm Making this propeller or mathematical measurements or anything doing what looks about right and With a water propeller It's nice to have it go like you know kind of like sweep back So if grass or seaweed gets caught on it Ends up falling off the end whereas if you have like more like an airplane propeller where it kind of goes straight out Grass and stuff can get stuck on it, you know, so this is kind of what they call a weedless propeller Yeah, so like on here any grass would just kind of come right off the end But if the propeller was going this way forward it has like more of a flat front edge Grass could get you know just stuck on there and just want to make sure I get All three propeller blades Pretty much in this I'm doing it again Because I put this on then I realized I want to draw the propeller thing on there first so I sanded the Most of the wax off so I could draw on it and now I'm waxing it in Okay What I've got set up here is I've got a block of wood. This is screwed down to it. That's all clamped in place The block of the block of wood has a hole so this goes in the right height and then I've got a little notch filed out of here So I put this on top and line it up with a line right here Do the first blade and then I can rotate it a hundred and twenty degrees until well Doing a hundred and twenty degree angle wasn't as easy doing a sixty degree angle So I'm just gonna check the sixty degree angle on the back side Which you put the front side at a hundred eighty degree or a hundred and twenty degrees And I do that propeller blade and then the same thing One more line over here, that's 60 degrees from that one Okay, last thing I'll lean the crowbar against it just to make sure this is Pressed up against there, so it'll be the same every time All right I'm gonna cut out some pieces of fiberglass that are this shape was enough to go up onto this I Think I'll do three this shape and then three a little bit smaller So I can do two layers on each the pallet blade at the beginning Once I have one of these good I can Trace it for the rest You keep the stinky fumes going out the window Okay, no scrubs no scrubs All right, it's definitely more than I need I just need to let that cure After cures I should draw The line So they can trim it so they can be all exactly the same Hey, do you smell any resin? Do you know what it smells like? Smells like nail polish Do you smell any right now so you don't smell any right now do you? All right, you'd definitely be able to smell it if you smell it I kind of want to take this out into the Sun because Sun cures this stuff Faster But if I do that I'll have to disconnect it and screw up the alignment of everything so It's like it's pretty It's pretty solid Fanster Oh No before I move it Chantel this is showing up And I hope it is good wax job Jay Let's stick my head in the fan Previous one looks like it's not in the way The trick will be see how much of this gets in the way of the mold on the next one I might have to take some of that off whatever though Let's do the current step. Oh my line. Did you up good? This right two for two this one is probably gonna be trickier Trim that I just took the angle grinder to it It's the third one and mighty good so far Sure, it's not perfect, but that is pretty good looking Let's try the weaker one I can rotate this And a whole bunch of pieces cut to put on there And I just need to mix up some garbage and let's do it. I've got my fan going. Okay. Oh Yeah Little sandpaper and that'll look great Should be super strong now Now I have the conceptually easiest part just smooth it out, right? Oh sanding I can do some of it with an angle grinder But there's gonna be some sanding. All right It's not bad All right, I think I want to put some paint on it. Yeah, definitely some Sanding I could still do but That's good enough give it a test Make sure everything's good And I just I just want to test it. I don't feel like sanding anymore. Okay. Oh, okay now that I'm clean and not feeling so disgusting I do kind of want to sand out these divots or Get resin on an end of a stick and just put little dots everywhere. There's a little pit Okay, it's tomorrow. I'm somehow not itchy which is amazing and I think I'm gonna tackle these little dents All right, I just decided to sand the whole The whole propeller blade I'll do the other side after And I'm gonna mix a little bit of resin and find something flat Not this but something better than this that I can use to just smear And get the little divots all the scratches get everything out of there. You know what I've got I've actually got the thing for this All right, fingers crossed. That's pretty good Let that fast cure in the sun I guess we'll spray it Oh, it looks pretty good, of course as soon as I spray paint and silver Any blemishes will really stick out. Where let's go Oh, that one looks great. Not bad Yeah, good enough Okay No, I better just wait. All right. I gotta go eat some food or something I'm gonna come back to this in like 15 minutes when it's definitely dry. Otherwise, I'm gonna get fingerprints on it If I measured this hole right, I should be able to put this on the boat Get a lined up with a hole that's on the color shaft Then drill through the other side and it'll be all lined up and then That's screwing. I don't want to drill through the other side Here because it won't be perfectly lined up Well, it looks pretty good Here's the rest of the boat Take it out. Oh, I guess I better get this one out of the way Yeah, this is the boat we're doing. All right, let's go test it out
