 I'm looking for a fan that'll just make a light breeze and not use a lot of power and all i'm finding here to buy is like tornado this and like 250 watts of like mega i think i gotta do something myself several years ago at the scrapyard i got two of these i don't know these were exhaust fans of some kind for something and i stuffed them into these pieces of pvc just to kind of give it a holder you know let me get it out all right so it's not the worst thing in the world but they're so they're not designed very well first the wind's blowing this way and then it's got this this frame blocking a bunch of the wind and just messing up the thing and then it blows through the wire too second this propeller is terrible oh my god look how look how look how not aerodynamic this thing is it's got these these things that you know make it stronger but i think what i need to do is i need to replace the propeller the motor works well and it's low power and it's pretty quiet and if i can just get a good propeller on this it'll make a nice breeze all right let's plug this thing in to make sure it works without losing my fingers all right so the motor totally works fine it was kind of all right but like right here i can feel the breeze but like yeah i feel like there's a lot of room for improvement if i can improve this here propeller so let's make a new propeller for this thing and then figure out how to mount it better and whatever this is the one i was just looking at here's the other one and i hammered out those those dents here to flatten them out and bent the propeller blades so they're blowing this way instead of that way over all the stuff and it's a marginal improvement but i think i'm just gonna totally get rid of the propellers and make total new ones yeah it's not big enough of an improvement to keep all right this screws on i found out when i was dismantling the other one i'll keep that to get pretty rusty little rubber thing that connects there well this one's different than the other motor that means basically the same thing okay that's what i have to connect well anyway let me figure out how to make a propeller that'll fit on this little thing here and figure out how to secure it kind of thinking of a wood propeller this wood is nice hard wood but it's too thin this is all stuff i cut on my lumber mill that piece right there yeah that's the same kind of wood it's nice and hard well look at that curve on that piece of wood all right how wide do i want this propeller to be definitely wider than the original but not so wide that the motor's gonna you know be working too hard and overheat or anything i went with 28 centimeters long probably a good size i can always trim it shorter when i get any curves or divots out of this thing make sure it's a nice smooth uniform piece of wood i think there's a low spot right there this piece of wood is obviously too thick to fit on that bolt i'm gonna have to drill with uh what are those things called forstner bit and drill a big circle and just it's in there yeah okay i gotta get this right in the middle 28 28 divided by 2 is 14 this i mean five centimeters across this one here's my dot my starter capacitor is dead on this thing i think that's deep enough to drill a hole the rest of the way through a little bit less than a quarter inch uh you know maybe i should drill this hole on the drill press to make sure it's 90 degrees but this part's so thin that's not what keeps the blade from going out of whack it's pressing up against this anyway and i have all this all right that's a little bit too small but i'm hoping i might even make it a bit bigger than that i'm hoping i can thread it onto here so i'm thinking my hole here should be just the right size to be able to screw onto here yeah beautiful okay let's get this on let's see if i have a little bit of a wobble you know what i can actually tell by looking at it this side slightly wider than this side so i have to shave off a tiny bit of here all right yeah that way nice thing about doing this is i always get lots of good fire starting pieces okay now i've got a decision do i want to carve the propellant blades in some sort of scientific manner with measurements and stuff or do i just caveman it and use my instincts and blah blah blah you know i feel like just taking an angle grinder and eyeballing it i know what it i know what the propeller shape looks like i can do enough of the roughed out math in my head to get it pretty close i mean way better than this anyway all right all right the basic the basic shape i'm trying to get right now is just like roughing out something where the ruler starts out at a certain angle and the closer i get to the middle the more it goes this way at an accelerating rate so it should move slowly at first that way and a lot more at the end yeah i think that looks really good all right i think maybe just some fine tuning i think that's that's basically a pretty good shape still feels strong i picked a piece with no knots in it uh i think rounding out these maybe i don't know maybe yeah i definitely don't want pointy edges in case little kids stick their fingers out um yeah maybe i just get some sandpaper and smooth smooth it out i think that's good oh and i did it with two power level things left to go and i better get my room out you want to sweep too grab the big room and do the floor just make sure you don't fluff it up and don't breathe the dust breathe it or sweep it slowly okay all right that ends looking pretty good oh i got some work to do there it's not perfect but okay you plug that in and then balance this propeller else who's probably gonna wallop all that wait wait flip it over don't force it whoa that is a lot more wind oh wow pretty good hey all right it is that wow that is all right unplug it it's definitely wobbling a little bit so i want to get the propeller balanced better but man that is way more wind than it did before how you bounce the propeller more how am i gonna bounce the propeller i you don't know yet okay the answer to your question stick a drill bit in there let's see okay that propeller blade down there is heavier than the other one definitely heavier so i have to file down this one yeah it actually feels a little bit thicker than the other one yeah uh all right thin this one out a bit oh and there goes my nice sanding job hey that's pretty good plug it in remember the plug goes one way not the other way well that is much less wobbly hey wait wait don't get in the frame okay ready don't don't touch the blades you can't see the propeller blades but they're right there okay so don't go in yeah that was a way more wind isn't it hopefully it's not using any more power than it was before man that is a lot more wind though but um you know those other propellers were so inefficient plus there were six blades well this came off the back of here although i do also have some mounting holes here those might be better for making some kind of and the screws fit those two yeah maybe i'll that is great these need to be shorter everything else oh wait no no no we only need two lock washers we need four of those so bring two of those two more of those and two shorter bolts there you go that's what we're looking for nice work give us some five here um bolt washer bolt washer up through the middle no no wait no no back up back up washer right here now put it up here all right i got it another washer and a lock washer wait flip your washer over this totally doesn't matter but i always like them that way yep in and out here and that's good job okay go tighten try not to hit the propeller though we don't want to dent it the propeller is a precision item you guys think that's gonna tip over it's pretty heavy down there you can always bolt something to the bottom if it does tip over all right i guess let's go give it a test all right we gotta plug it in carefully because i have to make sure it's not i'm not a hundred percent sure that it's not going to tip over all right go ahead and plug it in the right way flip it over flip it over you're doing the same thing valid tricks me see one of those plugs is longer than the other one so it only fits in one direction and over it all in it that's good oh hit the fan okay you guys i'm not gonna put a guard on this fan you know how mostly fans have a thing around it i'm not putting one on so you have to pay attention and be smart enough to not stick your fingers in there or walk into it okay i'm not gonna leave it in the middle of the floor i know you can kind of see i can see it goes right out to just right there anyway i think that's a great fan i kind of wish i could test how much power it's using
