Just a quick incidental update to show where I'm at with the belt drive system to replace the chain drive which was mostly working but I wasn't completely happy with and also the use of a hoverboard wheel as a alternator. So this is the wheel that the vertical axis turbine would be built on and this is a two and a half meter long ways grooved belt that I pulled out of a range rover in a on at a water records. This is a skateboard wheel like a long board wheel which I've put in this pillagell here and just put a bit of a groove in. You can see that with a with a file so that the belt doesn't skip out of it. I got for like ten quid on gum tree. Some guy was just selling it off the spare part. It's about a 350 watt three phase alternator when used as such and I've mounted it. As you can see I've just put two holes through the metal there and chuck bolts on these kinds of counter sunk tight bolts so that it digs into the axle and locks it off nicely which seems to be about the easiest way of mounting it in such a way that it can slide up and down if I were to need to adjust the height here to line up with the wheel. And then this would be the main pole that the turbine would mount it on and I've just put like two bits of bolt there to wind it in and out for the tensioning of the system and also let's me like set the verticality of it and all that. And then this is just a diagonal just to press the whole thing off nicely. I've mounted the wheel just by flattening those two ends and drilling a hole together so that's super simple, quite solid. And then that works like that basically and you can see if I can put it right. That's doing voltage like about 20 volts which is just me doing it by hand so it's fairly arbitrary as to what wind speed that would correlate to. So I've just got the three wires coming out the top there and that's pretty much it. So it's all pretty simple like everything that's here cost me I don't know 15 pounds or something and it all seems to work quite well. So the, oh and the valley basically of the wheel there I just bolted in some nylon webbing and that's just to stop the belt from basically like climbing into that dip and coming up the inside of the wheel which otherwise wants to do. That's a quite finicky thing, they're difficult to stop getting going all over the place. Like this the skateboard wheel just on its own just flat the thing like the belt like climbs up. Like not so much having it on the tight side but you always want your tension to pull the on the slack side of the belt and yeah climbs all over the place. I got some other more standard skateboard wheels like the more like round type and they were no good at all like the belt just slipped straight off so I got like a long board wheel which is fairly like wide and flat and also a bit like bigger as well. You want like a large radius tensioner pulley just for reasons of efficiency and you can see the grooved pulley which came off the alternator of the Land Rover was a bit of work to pull it off. I needed to sort of ask a guy who had the right tool for that and that's about a 45 mil diameter and this is a 26 inch wheel. I've been using 27 inch wheels previously for the turbine but I'm rejigging it to bring it down to 26 just because it's a bit more available. It also means as an added bonus you get more like distance that you can have this away because it having like a smaller circumference means the belt can come out further which turns out to be very necessary because the edge of the turbine itself is going to come out to about here. So as it is it'll miss the alternator but with a 27 inch wheel the alternator will be sitting about here and it wouldn't so it's important to use a 26 inch wheel. I'm updating the template for the turbine so that it sits on a 26 instead of a 27 and I'll do the update the tutorial with all that as well but you can see that works basically. If I put this under load it doesn't slip very well like the tension on this belt is not too bad. It's not enough to put much resistance on the system but it's still grabby enough that if I like like breached these together so it was under maximum load that this was pulling it'll be like but it would slip a little bit on the pulley and on the bike wheel but considering that's like a ridiculous amount of load it's the dynamic is pretty good like it's sort of sits in a nice sweet spot all this which is something that the chain system didn't really and it's also much quieter because it hasn't got that metal on metal dynamic which was the main thing I didn't like about the chain to be honest. And there's just being an automotive belt like most fan belts alternator belts are a lot shorter than this but out of vans trucks and and Range Rover's Land Rover and that sort of stuff you can get these two and a half meter ones. I have cut this down so that it fits into the wheel nicely like this was I think seven like seven ridges and I'll take it down to five just so that it fits really nicely in the wheel here so I just put that through like bandsaw and then I just sort of sanded it down and got a bit got a bit nice. Generally the workload of getting all this set up is not too bad there's not really anything in here which is like super demanding like you got to spend like about half an hour with a file like to get this sort of like nice and and troughed and flat but everything else is pretty easy. So that's basically the the simple way of mounting all of these elements together I'm going to be now that this is seems to be working okay I'm going to be taking this out to my mates farm in the hills and putting up a turbine with a belt and another turbine with an electric bike wheel having them both on the same pole and just sort of seeing what happened basically and I will update your win I've got more information.
