This project goes over the build of a simple and basic DIY chainsaw mill from start to finish. This chainsaw mill is portable and doesn’t require very large space . This is a very inexpensive way of producing lumber from logs and can be made from easily available materials from your local hardware store.
The materials you need to build this chainsaw mill are one by one square tubing, half inch square tubing, quarter inch flat bar, weld nuts, bandsaw and welding unit. The welder used here is Millermatic 212 auto set mig welder and the saw is Homelite 1130g
The dimensions of the saw are as follows. A 12 inch deck to slide across the log that acts as a milling surface. The max width of the mill is 26 inch. An 8 inch metal to grab the bandsaw on both the sides. A quarter inch flat stocks for the holding the saw.
We start by cutting 26 inch pieces for the sides and 12 inch pieces for the sides. Assemble them into a rectangle and weld it using a MiG welder. Do Check if the corners to make sure it is square and the sides are even.
A center bar welded into the rectangular guide plate, just to give it a little bit more support and make it so that it doesn’t twist.
Two guide posts are welded onto the sides. 2 larger pipe sections of dimension one by one is cut .This will slide within the guide posts. This is done so as to make the saw adjustable to how thick it cuts a slab .The side posts also gives you adjustability on the deck to move up and down.
4 quarter inch flat bars of length nine inches are cut . Two of them are bolted onto bottom section of the rails that slides up and down on the guide posts . The saw blade is placed securely between these bars. A small spacer block is welded onto the bars so that it doesn’t touch the saw blade. Three eighth inch weld nuts are welded onto the side posts . Tightening with the bolts locks the adjustable rails in place.
A crossbar is welded onto the guide posts .These help push the bar along when you are operating the mill and it is a nice place to put your hand , It feels like you are farther away from the chain.
The chain saw blade is inserted between the flat brackets at the bottom and it is locked tight in place between the spacers using 3/8th inch bolts.
For the first cut, we attach a flat plate at the top of the log so that the bar has something to ride. The height of the cut is adjusted with the help of the side rails on the mill . The saw is then started and placed on top of the flat plate to begin cutting the log.
- DIY Video:How to build an awesome Roof Top Portable ABS Pipe Hot Water Heater/Shower . Great for Camping/ OutdoorsThis project goes into the build of a DIY solar powered pressurized roof top water heater and shower that is portable for outdoor survival and camping trips. This project is easy to make and requires only minimal tools and plumbing parts. The dimension of the pipe used for this build is six feet tall and four inch wide. This has a capacity of 15 liters. The materials you need to build this project are six feet long four inch ABS pipe, air compressor, two four inch PVC end caps, abs cement, rubber schrader valve, shutdown valve and retainer nut, radiator valve drain plug , forstner bit,two inch threaded end cap, high heat flat black paint, steel wool scrubber, methyl hydrate. The shutoff valve is installed as low as possible in the pipe to avoid the necessity of having to tilt the system. Mark the position for the valve keeping the retainer nut in place , we insert a forstner bit into the nut creating a center mark for the drill .Once the hole is drilled ,we thread the shut off valve into place and attach the retaining nut. For installing air compressor for pressurizing the tank ,we use an long schrader valve that is used for aluminum rim tyres. This valve uses threaded nuts to secure it in place . Next step is to install the water intake opening. For this we use a two inch PVC threaded adapter socket . We take the diameter of the fitting and then drill out the opening and glue the fitting in place using ABS solvent cement. A radiator valve drain plug is installed on the threaded end cap of the water intake PVC fitting .This valve helps to release extra pressure from the tank without opening the main drain shut off. In order to improve thermal absorption of solar energy, the surface of the ABS pipe is painted with flat black paint. The surface is polished with steel wool soaked in methyl hydrate and applied one coat of spray primer followed by two coats of high heat restoleum black paint. To mount the shower to roof of the car or truck , we use a canoe foam block . We extend the slots in the foam block to make them fit inside the cross rails . An arc is cut on the foam block equal to the outside diameter of the pipe and positioned it such that it left half an inch of foam between the mounting slot and the bottom of the arc. To attach the shower to the support pads, here we use one inch nylon tie down straps. With both these pads in place, the water heater is securely attached to the roof. An inexpensive 25 foot long coiled three eighths inch hose from the local garden center is used as the shower hose. This would be perfect as it is easily stored and can be taken apart after use. The air compressor is connected to the pipe with the help of a multifunction spray nozzle . Thee bursting point of six inch ABS pipe is well over 100 psi .So a 30 psi would provide safe and ample pressurized shower without any long term expansion fatigue to the pipe or glue connections . https://www.youtube.com/watch?v=dG2HK9JsAjw
- How to heat your Garage by using an Outdoor Wood Burning Boiler and an old car radiatorThis project goes into the build of an outdoor wood boiler for heating your garage using an old barrel and a car radiator. The first step is to make a wood burning stove out of an old barrel . Here we are converting the barrel into a stove using a vogelzang stove kit. We start by cutting a hole for the door using the the door accessory from the kit as a guide. Place the door on the side of the barrel and mark the four corners. Start cutting the hole using a grinder, reciprocating saw or a plasma torch. Align the door with the hole and drill holes for the screws. The door is now secured in place . Next step is to install the legs that came with the kit. Place the barrel on the the legs and align them so that everything is level. The spots are marked , holes drilled and the legs are bolted in place. To control the air flow and how hot the stove burns, we install the flange and the damper within the chimney area. Center the flange that comes with the kit near the edge and make a circle for cutting the hole. Also mark holes for the bolts using the flange as a guide. The flange along with the damper is then screwed down securely. The next step is to convert this barrel stove into a hot water heater. Begin by drilling two holes across both sides of the barrel and inserting couple of three eighth inch threaded rod across the sides. This creates a base where a 30ft coiled copper tubes are placed to circulate the warm water. A 30ft half inch copper coil with the input and output straight end is placed inside the barrel on top of the two threaded 3/8th rod base which we have installed previously. Two holes are drilled at the back of the barrel so that the input and the output ends of the copper coil can be connected to a pipe or flexible hose. The input end of copper coil coming out at the back of the barrel is further connected to another loop of copper coil outside the barrel . The coil is wound across the barrel so that incoming water is preheated using the outside coil before it goes into the barrel and gets further heated by the coils inside . The ends of the coils are connected to two pipes, the outgoing and the return . These pipes are then insulated using half inch pipe insulation foam to prevent any leak. A small trench is dug and the insulated pipe is extended to the garage. The water circulatory pipes are now connected to an old car radiator inside the garage. The incoming hot water pipe is connected at the top of the radiator and the return is connected at the bottom. To circulate the water ,we use a cheap submersible pump. The pump is submerged in a bucket . The pump will pump cold water out through the heater, the hot water circulates through the radiator , cools down and collected at the bucket and it is again recirculated. Two holes are drilled on the top of the bucket . One for the pipe coming out from the pump and another for the pipe coming back from the radiator. The inch and quarter radiator hose is adjusted to connect to the pex hose piping with the help of a PVC poly tube with a threaded end The other side of the polytube with the threaded end is attached to a PVC adapter and a slip fitting with a bushing. This helps us to connect the pex pipe to the radiator . To prevent the water from boiling , an antifreeze solution is mixed . A window fan is used as a back fan for the radiator. Placed right behind the radiator, this blows the hot air through it and into the garage. https://www.youtube.com/watch?v=NPw9HKAxr8A https://www.youtube.com/watch?v=IBMSDp5puEE
- How to build a Homemade Archimedes Screw Turbine using PVC parts to generate Off the grid Power from a flowing river or stream/creekThis project goes over the build of an Archimedes Turbine that can generate off the grid power from a flowing river or creek. This is basically a screw that turns when water passes through the pipe. You need a 5 foot farming auger to build this. The farming auger is put inside of a 6 inch pipe and placed in the creek at a certain angle, water would pour into the auger and that water would weigh down that auger and turn it. And so as it turned, it would turn a shaft that is attached to the end of the pipe and run a pulley system with a motor to generate electricity. We take an old belt sander and shave some of the edges to make it smooth and rotate without any friction inside the pipe. We use an angle grinder to split the pipe down the middle and use the separator nuts to kind of give more space in the pipe. Make sure you don't split the pipe into two. Open up enough space on the top by heating the PVC and clamp 2 spacer boards on either side and stretch the opening by using a C clamp. 2 three quarter inch boards are bolted using carriage bolts on either side of the pipe which gives us enough room here to get the auger installed. Allthreads of size eight and quarter inches are put through the boards and secured in place with the help of some washers and non locking nuts. https://www.youtube.com/watch?v=GTD5Y7EyK00 https://www.youtube.com/watch?v=GTD5Y7EyK00 https://www.youtube.com/watch?v=jwIfrIgVqZc https://www.youtube.com/watch?v=veb6xTz7Vhg https://www.youtube.com/watch?v=Ul76_kG0xyI https://www.youtube.com/watch?v=v4I9Zfp62F8 https://www.youtube.com/watch?v=Oqt38fbsQaA
