This project goes over the build of a simple Bandsaw from old car wheels .Car wheels are big and heavy, but in many ways, they are ideal for bandsaws. They are available everywhere cheaply. They have a rubber tire for the blade to sit on, and they have excellent bearings.
Take apart the brakes, the backplate , bearings and the stub axle out of the housing. Weld the stub axle onto an off cut of scaffolding.
So we now have two wheels, spinning on the ends of two straight lengths of steel.
We take some scrap angle iron pieces and make a rectangular frame for the mill. This form as the base of our mill.
In order to make the sliding mechanism, we take a scrap pipe and try to fit it onto a square iron pipe so it can slide in and out smoothly. This will be used for all adjustments. This is welded onto the frame.
A Steel plate is welded onto the sliding bars. This is for the engine to sit on. The engine will drive one of the car wheels
We mount the 11 HP Petrol Engine to steel plate and the tire is connected directly to the engine shaft through a drive belt.
The drive wheel is bolted on to the frame ,also added a lever for the engine mount which will act as a sort of clutch, tightening and slackening the belt when necessary.
We add two more pipes on the bottom of the frame and slid them to the support platform of the second wheel made from the same square box iron and some short sections which is part of the blade guide.
The second wheel has to be adjustable in a few different directions and has to be lined up with the first wheel so the blade stays on them both without running off the tires. To adjust the tension on the blade by moving the wheel away from the first one, we use a bottle screw.
The blade guides are made from cheap bearings. They needs to be adjustable so that the saw can cope with logs of different sizes. The blade guides help keep the blade straight as it goes through the log and also stops the plate being pushed off wheels
The band saw has to go up and down so that it can cut planks from a log. We make a simple frame to hold it. It has to fit inside vertical pieces of angle iron on the saw. The support frame is bolted onto to the saw by using a bracket which grip the uprights.
Couple of barn door pulleys are bolted onto the top of the support frame and the mill frame. A trailer winch is bolted on to the middle of the support frame. Using a 3mm wire and winch-pulley system, we can move the wheel frame up and down.
Two short pipes are added at the front and these hold up a guard which can be taken off when we need to get at the belt or the blade. If the blade snaps, the side guards should make sure that it heads down towards the ground and not up to the ceiling.
The saw is stationary and the log is moved through it using dolly trailers or rails.
- How to build a Backyard Waste Oil Burner Powered Water Heater to produce Free Hot Water for your HomeThis projects goes over the build of waste oil powered free hot water heater for your home .This converts an old used domestic water heater to run on waste oil, engine oil or cooking oil. With as little as one liter of waste oil, this heater gives twice the heat output than a domestic electric powered water heater .As waste oil is free, this is more economical than running on gas or electric. The setup of this waste oil heater is very simple and easy. We have a waste oil burner that is placed under the domestic water heater. The burner is connected to a blower from a car. This blower is powered by a 12V battery charger . The burner is also connected to a drip feed waste oil pipe through a small pipe. The oil feed from a suspended tank, which gives it a gravity feed dribbles into the inlet pipe on the burner and it is simply blown into the burner by the force of the air from the blower. To control the oil flow ,we have a valve on the oil tank. The cold water comes into through the inlet hose at the bottom of the tank . From there burner just fires the heat up through the center of the heater as it would normally if it was gas fired. The hot water comes out from a outlet hose at the top of the tank. The waste oil burner is made out an old fire extinguisher bottle. The beauty of using extinguisher bottles is you don't have to worry about any flammable gases in them, and the metal seems to be quite durable. Make sure that the air and the fuel enter the bottle at a slight angle in order to create some swirling. This makes sure that the air and the fuel mix and will burn completely. And also that the bottle is kept hot so that the liquid oil will vaporize and the gas will burn. The inlet pipe for the waste oil and the blower is positioned at 25 to 35% of the way up to the bottle. The inlet pipe has a small bend in it so as to promote swirling within the bottle. This is important in keeping the bottle hot and self sustaining. The burner has a clean burn with almost no smoke. The output of the oil burner can be controlled by the amount of waste oil being dripped into the burner and by the amount of air blown into it. This oil gas burner is more powerful than a gas burner and the heat produced can overpower the heat sink threshold of the water heater . A vent line is installed on the system so that any build up pressure can be released. Apart from heating hot water , this set up can be used for space heating , pool heating or garage heating. https://www.youtube.com/watch?v=L4xq_GSjWLI

- DIY Video : How to Turn old unused ceiling fans into a useful energy producer by building a Wind Turbine out of itA Beginner tutorial on how to make a wind turbine ceiling fan.So out of the box, we have the main part here, which has the motor in it.Keep up with all the blades if you can. You can use this for the furrow on the back the way it pushes around to keep the turbine from standing in a very aggressive wind it pushes it out of the way First part is just getting the motor outside of this casing. And you want to be careful because these wires are fragile, and you don't want to tear those loose by any means.So mainly, the tools that you'll need is just a screwdriver, maybe a flathead screwdriver and a hammer eventually. Take the top part of the ceiling fan off, this is the part that's next to the ceiling.Disconnect the wires don't cut them. There's a nut here with a washer that holds this plate.And we don't want this plate. So we need to take that off. However, we do want the washers here. Take this casing apart, and inside you'll see that copper coils that actually power the fan. The next step is finding the highest arm reading of these four wires that is coming out of this motor.Pull that higest ohm reading wires through the center pole to the other side. Insert a metal banding used for attaching the magnets around the stator. Put the magnets inside the fan housing to achieve a voltage reading.Add a cardboard spacer in there so that the magnets are aligned with the stator. The blades are made of 4 inch PVC.You can find templates online for the blades.Put the outline of the blades from the paper onto the PVC and then cut it out with a jigsaw. And then once you cut it out with a jigsaw, all you have to do is get a little Sander out, you can use a hand Sander to smooth the edges off. Connect the blades to the faceplate of the old ceiling fan. Next step is to take an inch galvanised pipe that forms the body of the turbine. A 40 inch piece will slide down into the conduit of the mounting system for your turbine.A 30 inch piece on the back,This is going to be angled up into the wind to keep the blades in the wind a little better. One Inch PVC is slid down the end of the 30 inch pipe and attach the tail piece on there which is made of fan blade The wires from the fan is passed through the pipe and just zip tie them down.Cut the PVC in half to a 45 degree elbow ,cut a line down through this PVC, we're gonna split it basically and drill some holes in it and attach the ceiling fan blade. Attach the fan to the galvanized pipe with the help of an extension that was previously saved during our dismantling of the ceiling fan.Use JB weld on the inside of that. And I put this bolt through this part and put a tightening screw on it, they're kind of digs into the metal. Connect the two leads from the fan to a bell wire, solder these two together, wrap it up with some electrical tape and kind of zip tie to the top so that it will stay in place.At the base end of the wire,connect it with a diode bridge rectifier which is further connected to our battery. Regarding connecting the rectifier,it doesnt matter how you solder them together,just as long as they are separate and not connecting and shorting out. But you want to put this at the base of the wire at the very end so that you can put this inside of your battery box and hook it up to your battery. https://www.youtube.com/watch?v=sr9ZMbF3Zqk&list=PL68TKRSLgXzQqZa5WzMNFwmYKS4b4KPcA
