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 Offgrid Homemade Emergency Washing Machine that use no electricity.Also works as a ComposterThis project goes over the detail on how you can take an old 55 gallon plastic drum and turn that into a hand crank washing machine and a compost tumbler. The frameworks has uprights on the edges, holding up the barrel all the way down. The upright on the sides are 3 foot long 2 x 4. The base that it sits is 3 foot 2 X 4.Long brace that holds the two sides together is three foot eight inches long. You can take apart the whole framework by unscrewing the side rails and store the barrel for using them in an emergency situation. The barrel sits on a one inch hardwood dowel which is installed through one inch hole at the top of the upright. These barrels have a line in the middle of them so it is pretty easy to find the center by measuring across the line and then dividing it in half. The hand crank is made of PVC pipe with some screws to the end side of the barrel. The hand crank gives you something to grab onto if it gets very heavy so you can pull it back up and really move it around. It has a one foot by one foot door on the front .We use couple of cheap cabinet hinges to hold the door up when unloading the clothes. It also has a little S hook latch that locks it into place. A hole down in the middle of the barrel is for drainage. A small plug and a cap acts as a drain. The plug is put through the hole from inside and sealed with the help of PVC glue. Next step is to add agitators to our barrel . As you rotate the barrel, the clothes will roll over those agitators back and forth and get the clothes moving a lot better and help clean it. We add 3 PVC pipes inside the barrel that act as the agitators. You put clothes in through the top and add enough water just to cover the clothes, add any biodegradable liquid detergent and close the lid. Start moving the hand crank back and forth. This will agitate the clothes. The agitators slosh those clothes around, get them grinding against each other and that is going to clean all the dirt out of them. After about 15 minutes of agitation, we pull the drainage plug off the bottom and drain the water or recycle it by collecting them underneath a bucket and pour it around your plants and trees. As long as we are using biodegradable soap/detergent, the soap and the dirt that is in your clothes isn't going to hurt the plants. We put the plug back on, and fill the barrel with some clean water and agitate for another 15 minutes. This is the rinse cycle. Pull the plug, drain that water or use it on your plants. This setup can be also used a tumbling composter. Compost can be made of just about anything that was once alive .You can use leaves, grass clippings, garden waste, kitchen waste, chicken manure or any other waste material. Just dump all in there and turn the compost in there using our handle every couple of days for 2 weeks. We want to keep the compost aerated so that the microbes and bacteria that break down the compost can utilize the oxygen efficiently and help in decomposition. After 2 to 3 weeks, you probably have some pretty decent compost that you can use on your garden. Also through the drain hole, we can collect the residue compost tea which is high in nutrients. You can use that compost tea for plants that really need a good dose of nitrogen.

- DIY Video : How to build a Homemade Atmospheric Water Generator . Produces/Extracts Distilled Water from the airThis video shows the build of a Homemade DIY Atmospheric Water Generator!.ThisUnit pulls Pure 'distilled water' straight out of the air. This simple design pumps near freezing water thru a long section of copper coil. Coil becomes very cold and dew (condensate) forms on the coil. The dew is then caught by a drip-pan located beneath the coil.This unit has the added benefit of dehumidifying the air.I used only aluminum and copper in this version. main thing with these is to keep the coils clean. if coils are cleaned after each use, the water generated is 'distilled water.
