This project goes into the build of a homemade DIY Water distiller that can purify dirty and contaminated water and desalinate salt water into clean drinking water. The total cost of this build is about sixty dollars. For distilling water, you need three thing – water, a source of heat, and some sort of apparatus that will allow water to boil into steam and then recollect that steam , condensing it back into usable water.
A water distiller basically needs to do two things, it needs to boil water to create steam, and it needs to capture that steam in a way that allows it to condense back into water. The materials you need to build this distiller are six quart stainless steel pressure cooker, 20 foot three eighth inch copper tubing, two gallon bucket, jb weld, zip ties, flat bar, five sixteenth inch silicon tubing, mason jar.
The first step is to boil the contaminated water in a tea kettle or a pressure cooker. Here we use a six quart stainless steel pressure cooker. Since the boiling water must be directed to the condenser, something with a sealed lid of some sort is needed. The existing pressure valve of the cooker is removed and replaced with a barbed fitting .A small rubber O ring gasket is used to tighten the new fitting.
Next step is to make the condenser. The purpose of a condenser is to give steam the opportunity to cool back down enough so that it turns back into liquid water. The condenser is built using a 20 foot three eighth inch copper tubing. This is reformed into a tighter and taller coil such it will fit into a two gallon bucket.
Because it needs some sort of support to avoid having the coil collapse under its own weight, a flat bar bent into a U shape is placed under the coil. A small cross piece is attached to it at the bottom using JB weld. The coil is attached to the punched bar with some zip ties.
A hole is drilled near the bottom of the bucket to allow the copper tube to drain out the condensed water . The coil is placed inside the bucket carefully and the tail end of the coil is pushed into the drain hole .
The condenser is connected to the pressure cooker with a 5/16th inch silicon tubing. A similar silicon tubing connects the bottom of the condenser to the clean water receptacle like a mason jar.
When distilling water , cooling the steam back down is very important. The coil itself will cool some of that down. But that alone isn’t enough at this scale. It will end up losing a lot of steam through the bottom of the condenser because not all of it has been able to cool and condense by the time it reaches the bottom.
An efficient way is to add a cooling element to the condenser. Filling the bucket with ice water will increase the efficiency and water output by a lot because it will cool the copper tubing much more than air alone. Doing so had an immediate effect and all of the escaping steam condensed instantly to liquid water. By periodically adding cold water through the distillation process, it practically eliminated all of the steam waste coming out of the condenser.
The gap around the copper tube where the hole is drilled is not sealed. This is because of two reasons. The first being able to easily remove the condenser from the bucket for cleaning and maintenance. The second reason being it acts as a drain. The boiling steam causes the copper tubing to get very hot. Because of this, it heats up the cool water very quickly and this drain makes it convenient in that the water will drain out before it gets to that point.
In a survival situation , set the condenser over a larger bucket to collect and reuse the cooling water as it drained out and not simply let it go to waste.
- DIY Video : How to heat your garage the Inexpensive way by building an Outdoor Stove with Heat ExchangerThis project goes over the build of an inexpensive garage heater using DIY outdoor barrel stove with a heat exchanger. This outdoor setup is safe because you dont want the stove inside the garage to catch fire if you are working with any flammable gas. We use a 30 gallon drum for the stove. The access doors and legs are purchased from the local store. The heater exchanger is made out of four inch steel pipe .We take couple of 4 foot pipe and weld them together using another small pipe. This pipe goes inside the firebox and connects to the chimney pipes. The pipe should be thick enough that it can withstand the heat of the fire without sagging or bending. This pipe heat exchanger adds positive pressure . Removable hatches are made on one side of the stoves to connect the 2 four inch aluminum flex chimney pipes from the outside barrel to the garage. Inside the garage we place a 4 inch exhaust fan blower that sucks the colder air from the floor and blows it through one of the flex chimney pipe into the stove. The blower is actually a hydroponics duct exhaust fan purchased from Ebay. The cold air gets pushed into the stove and moves through the heat exchanger steel pipe , gets heated and then moves out through the second chimney flex pipe and back into the garage. The hot air from the stove moves into the garage through the second pipe. In order to get more hot air, we also add a drip fed waste oil system to the outdoor stove . The oil gets dripped slowly from a tank into a frying pan on top of the stove .You can add cotton rags and let it drip into there and it just keeps burning like a wick. The combination of both wood and waste oil produce better fire . If the stove gets too hot, you can turn of the oil or use oil only to maintaining the temperature. You can put an insulated shack around the stove to minimize the heat loss. https://www.youtube.com/watch?v=fn4CerxpNug
- How to build a Homemade Wooden Bandsaw Mill from Scratch.Step by step build InstructionsThis project goes over the build of a simple Homemade Bandsaw mill that can that turn hard maple into smaller lumber . The first step is to make the wheels of the mill. Here we use a three quarter MDF board to make this. The wheel size is 16 inch. We use a beam compass to cut circles and cut two wheels out of them. We make a seven and half pulley for the wheel using a three quarter inch plywood and drill a five eighth inch hole into the middle where the shaft goes. We take some hot melt glue and glue the stock collar onto the pulley and tighten it with a set screw so as to stop it from spinning. Before joining the wheel and pulley together, we make another small disc to go in between to act as a spacer .We glue the pulley to this spacer and from spacer to the wheel. Two wheel bearing blocks are bolted to the wheel on both sides using 4 three eighth inch threaded rods. Make sure that the threaded rods are tight inside the hole in the wheel, but the bearing blocks itself can move around. One way to keep these bearing blocks in place so that they dont move side to side is to apply some construction adhesive to the corners. Next step is building the frame for the saw from salvaged 2 X 4 boards. Make sure that the 2X 4's are straight. Take the bench hand plane and smoothen the edges so that the boards sit flat. It takes several shallow passes flipping the woods each time to get rid of all the twists and warps. Two frames pieces hold the wheel in ,the stationary drive wheel is placed eight and half inches from the end. Two five eighth inch holes are drilled on both the frames so that axles fits in there neatly. On the other side, one holes are drilled that gives the room to adjust the wheel. We also make an adjustment collar out of plywood that is bolted into the frame and the shaft . The collar can be moved to adjust the wheel. We also place couple of pieces across the frame and secure them tight so that the supporting boards are locked in position. On the other side we install the front wheel or top wheel. This wheel needs to move back and forth to put tension on the blade. It also must have a tracking mechanism. For that we make a two small piece that locks into the shaft on the front wheel and slides back and fourth. A guide piece is drilled onto to this piece . A one inch hole is drilled into our slider piece and a three eighth inch threaded rod is secured in there with a nut and washer. These rods help put tension on the blade and also adjusts tracking. Before putting the blades on the wheels, we put silicone caulking on the wheels to smoothen it out .These have advantage over bicycle inner tubes as it doesn't drape down over. The legs are attached to the frame using gusset blocks. To put the motor onto the frame , we take a melamine board and screw them aside the stationary wheel using a cross board. This piece of melamine not only supports the motor, it also helps to brace up the top to keep that from rocking. Secure them tight so that it resists moving while the cutting is going on. Next we make blade guides near the bottom to make a guard for the blades just in case it snaps and flies off. The blade guides are made of small piece of steel angle that is glued to a ceramic piece. The way blade guides work is that they don't actually touch the blade when it is running. It is only when the blade tries to move up or down that it will constrain it and keep it on track and prevent it from twisting. A thrust bearing made of regular size ball bearings is bolted onto an aluminum angle that is further attached to the blade guide. We make a dolly cart out of 2 X 4 boards and some castors to place the big maple logs and move it effortlessly through the blades . The castors are screwed in the ends using quarter inch holes. The castors are fixed in such a way that it moves only in one direction back and forth. https://www.youtube.com/watch?v=rhFEVf8zZkg&list=PLQl9KPrpiIH9Sk0wEiN9d0ANUOK-ntV-i
