How to build a simple and effective Multi Purpose Waste oil Aluminum Scrapping Foundry / Forge out of Scrap Metal

    This project goes over the build of a convertible waste oil powered aluminum foundry / forge made out of recycled materials. Waste oil burning does get more than hot enough to melt down aluminum, which has a melting point of about 660.3 degree celsius.

    The materials you need for this project are old 10 gallon propane tank for the foundry, air compressor tank for the waste oil burner, blower from a car , three eighth inch hose and a brake line for feeding waste oil from a bucket, 12V marine battery for powering the blower.

    We take a car heater blower and house them inside an old tin can for the air intake. This is soldered to soup can and one and quarter inch schedule 80 pipe .This feeds air into the burner vessel.

    The fuel source which is the waste oil is drip fed from a five gallon jug with a brass gate valve. It is connected to the blower pipe through a three eighth inch hose and a metal brake line.

    The waste oil burner is from an old air compressor tank .It has a two inch cap on the top where we start the ignition and light the system. The pipe from the blower goes half an inch into the burner at an angle. This generates a cyclone vortex effect . We want to make sure that the oil and air are very well mixed together. In order to sustain combustion on something that’s so difficult to ignite like waste oil, we have to have a source of heat so it can actually atomize, turn into a vapor where it will burn very easily and very effectively.

    The outlet from the burner is connected to the foundry propane tank through a three inch piece of axle welded with a rotating coupling piece. This can be rotated independently so that the foundry can be rotated to a forge mode with the help of a lever.

    We mark and cut the top of the propane tank that essentially forms the body of our foundry. Next, we are going to need to put a lining on the inside , probably about two and a quarter inches thick. This acts as an insulator. Here we use a 50% mix of plaster of paris and play sand. The propane tank is filled with the mix and the air compressor is submerged in the center to form a mould. We let the tank sit for 24 hours to cure before we remove the air compressor out of it.

    Next step is to create the hole into the side of tank that will be the outlet of our waste oil burner. The hole is cut at a height so that the the aluminum wont run down and back flow into the oil burner tank. We place a three inch axle through the hole that is welded to rotating coupling . This coupling attaches to the outlet of the oil burner.

    One the other side of the propane tank ,we add a small lever system with a latch to manually put the foundry into a forge mode.
    A one inch water pipe is connected to the tank .Inside of that one inch water pipe is this bit of one inch shaft with a hole drilled in to accept a three eighths inch bolt. A rebar with a latch mechanism is welded vertically to this pipe. The latch is pulled to pulled and the foundry is rotated into forge mode.

    The foundry sits on a cradle during the forge mode .The cradle is made out of two inch flat bar. The frame is constructed from one and a half inch by one and a half inch angle iron that I had laying around.

    To start the system , we use a little piece of rag cloth and poke it down into the inlet of the ignition port of the oil burner. We apply a little waste motor oil and start the ignition. Once the flame begins , we apply power to our blower motor by connecting it to the 12V battery.

      This video shows the build of a homemade 12V washing machine made from junk parts and pieces laying around.Most of the materials you’ll need can be found around your house and most certainly at your local hardware store.Great for going off grid for a while preparing to be survive in case of SHTF or are you just a regular old camper that needs clean clothes at camp.Laundry has come up a number of times as a self-sufficiency topic. It makes sense for a couple reasons. First of all, because many people in our crowd are wanting to be self-sufficient of the electrical and water grids, and need find another way of washing clothes. Secondly, because we are also usually looking for ways to save money.
