This project goes over the build of a homemade waste oil garage heater made out of an old standard 55 gallon drum and a propane tank. This setup also doubles as a cooker.
The first step is to make the Waste Oil Burner Unit. This is made out of a four inch tin can and a candy tin. Place the tin can in the center of the candy tin and mark around them. Cut a hole out of it with a chisel. Drill around 15 small holes around the tin can. The tin can acts like a chimney brining fresh air for the combustion. The open end of the tin is placed into the hole at the center of the candy tin. This burner uses a little over two liters of used waste oil per hour and makes lots of heat from that amount of oil.
Make sure that the propane tank is empty. Fill it with water and let it sit for a day before we begin to disassemble them. Once the tank is safe to work with, we begin by cutting two sections on the them and divide it into two chambers .The top one is seven inches high and the bottom one is three inches. We also cut two openings at the top of the tank for exhaust fumes.
We make a disc separator out a 4mm steel plate with a hole in the middle. This disc goes in between the upper and the lower chamber. We place the tin can burner unit inside the upper chamber . The lower chamber is for the air intake. Doors are made with the leftover cut pieces of the tank . The door for the upper chamber has a screen welded onto them for viewing purposes. The air for the combustion comes through the lower chamber ,passes through the disc separator hole and goes into the burner unit.
To radiate the heat , we place a 55 gallon drum over the propane tank burner unit . To make this unit , we take the drum and place it sides and cut out a portion . A steel plate is placed in the middle . This can act as a cook top . One the other side of the drum ,we make a hole so that it sits in tightly on the propane burner tank.
The two upright sides of the barrel is welded with a six inch steel pipe for heat distribution. This pipe acts as suction for the flue pipe . The flue pipe is welded onto this pipe in the middle . So the exhaust gas from the burner comes up and heats the plate over it ,travels up through the barrel into the pipe and moves out through the flue.
To control the waste oil coming into the burn chamber of the barrel stove , we use a drip feed system. The oil stored in a bucket is connected to a half inch pipe with a ball valve.
The pipe goes into a standard half inch gate valve and further connects to a pipe in pipe system. A half inch inch copper pipe is placed inside a one inch mild steel pipe .
The pipe coming from the gate valve is connected to the copper pipe which is inside the mild steel pipe through an elbow. These two pipes goes straight into our burner unit inside the propane tank. The oil gets drip fed into the candy tin of our burner.
To get started ,we add some kerosene and light up a fire using the torch. We slowly open the valve to start the oil feed into the burn chamber.

- How to make a Survival Rope Making Machine at home from easily available materialsThis 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 . https://www.youtube.com/watch?v=ddenqErLL0Q https://www.youtube.com/watch?v=uEvM6ue3L7E https://www.youtube.com/watch?v=RM9GY-n6PEA
