  • How to make a Survival Rope Making Machine at home from easily available materials
    This project goes over the build of a Homemade rope making machine using a simple cordless power drill and some inexpensive materials that are sourced from the local hardware store. Here are the materials needed for this project: Three quarter inch by five inch eye bolts with hex nuts Fender Washers Cut Washers Hex Nuts Plastic Castor Wheels two by two and one by six by six piece of lumber Old bicycle tire tubes Take the board and cut it to length of seven and a half inches and took the first piece and doubled it over the second one and cut them together so that they are exactly the same length. Then I took a piece of two by two and cut it eight and a half inches long. Take large fender washers and position them on the board forming a triangle, you want to do it in such a way so when you add your two by two to the top as well as the bottom, it has similar spacing at the top and the bottom. Put the two boards together, mark the centers and drill the holes. Next step is to build the metal spinning hooks. These spinning hooks are going to be made out of eyebolts which is used as a hook to put the strings on. We take 3 plastic castor wheels and use them as a pulley , connect them together with a small piece of bicycle tire tube so that when one is spun ,all three of them would spin together. We take the 3 eyebolts and push it through the hole and secure them tight with a small cut washer and hex nut. It is locked in place but should spin freely. Put with wheels through the bolts and secure them using fender washers, cut washers and nuts. Take an old used tire tube piece and line it up between the two washers and cut up a piece that is roughly about the same distance as that gap. We loop the tube over the pulley all at once.The Second board is pushed through the bolts over the wheel pulleys.Make sure everything is lined up symmetrically. When we turn one bolt, the belt drives the other two pulleys and they all spin together. As we are running the hook spinner, we are going to need something to hold it at the other end, To make the other end of the mechanism that holds the strings in place, we take six inch piece of common board and eight and a half inches of our two by twos on the bottom to secure it as a base and them we clamp it over a table. The idea is that as each hook begins to spin, the two cords attached to it will intertwine with each other. And then eventually all three of those cords will mesh together to make a nice three stranded rope. As the strands are twisted, it creates tension on the backboard. To relieve the tension, we drill a hole through the backboard and tie the rope to another counterweight rope through a swivel hook that pulls the tension and allows it to rise as the cord is pulled. We also make a rope makers top that will help guide those strands into the beautiful three strand cord. We add two ropes between the spinner mechanism as guidelines and connect it to the back board to accommodate the rope makers top. The idea is that as the tension builds it will glide forward and guide the individual strands into place to form a three stranded rope. We sandpaper the holes on the rope makers top to make it smoother so that the lines won't snag up when they start twisting. We put a wooden knob on the back to reduce the friction so that the rope makers top can slide smoothly. Loop the cords through each of the three hooks on our rope maker machine .Form a slipknot and connect it to the swivel hook. We have our rope machine build complete . To tie and cut of the rope, take a small piece of electrical tape and wrap it around the end where you want to cut it off. Cut The Rope at the back just where the electrical tape ends .
  • DIY Video : How to build an Awesome WaterJet Cutter at Home for Dirt Cheap .Build The Ultimate Cutting Tool
    This video shows the build of a $100K worth WaterJet Cutter for about $200 using a cheap pressure washer.Waterjet is the ultimate machine tool, no matter the application.This is because its a Cold Cutting Process which means no heat or stress is imparted into your cut materials.Also you can take the part directly off of the cutting table, no secondary finishing required.Also it eliminates slag deformation and dross waste – unfortunate effects found in plasma and laser cutting processes.

  • How to build a Homemade DIY Geothermal Heat Exchanger to Cool Your Garage
    This project goes over the build of a Geothermal heat pump that takes the hot air in your garage and cool it down by transferring that heat into water .The cold water is pulled out of the ground through a shallow hand dug well and send to a heat exchanger inside the garage . A fan attached to the heat exchanger blows out the cold air into the garage . The heat exchanger absorbs the existing heat inside the garage . The warmed up water is then removed through an exhaust pipe. Just a few feet down the earth is a consistent 55 degrees, summer or winter. Water at that depth is about the same temperature. To harness the cold water down below, we dig a shallow well. To do this we use a post auger and a 3 foot long well point that is attached to a 10 foot three quarter inch pipe using a drive coupling. We start by digging a hole using the post auger till the water table is reached and then start driving using the well point for additional two to three feet until it is submerged under the water table. A two to three foot trench is dug from where the well is installed to the garage . A One inch poly pipe is connected to the well pipe using a barbed coupling and is buried inside the two foot trench all the way to a well jet pump .The trench is dug down at least two feet until you hit some hard pan clay that is about where the temperatures begins being more constant. This keeps the pipe cool under the earth. The other end of the poly pipe coming out from the trench is connected a 1/2 HP Flotec Shallow well jet pump . The pump can be powered by a solar panel. The pump is kept outside the garage as it generates a lot of heat. If it is kept inside the garage, cooling effect from the water will be undone by the heat generated by the pump. The output of the pump is connected to a three quarter inch copper pipe inside the garage. It is then further connected to a water pressure tank with the help of a brass tee and a union. A relief valve is also attached to the tee to empty the water tank if the pressure gets too high. A water pressure tank is used prevent the pump from failure .It also acts as a buffer storage. The other end of the brass tee is connected to two pipes. One pipe goes outside the garage to a faucet and the other pipe is connected to a radiator that acts as a finned tube heat exchanger. The heat exchanger captures the hot air surrounding the garage and stores the heat into the finned coils within the radiator .The heat is transferred to the water flowing through them . An exhaust line from the radiator carries this hot water to outside the garage. Two flexible hose pipes connects the input of the heat exchanger to the water tank and output to an exhaust pipe. A box fan is placed in the front of the radiator to blow the cool air . The fan can be powered by Solar panels. Once the water starts running through the radiator , we start the fan
