This project goes over the build of a simple Bandsaw from old car wheels .Car wheels are big and heavy, but in many ways, they are ideal for bandsaws. They are available everywhere cheaply. They have a rubber tire for the blade to sit on, and they have excellent bearings.
Take apart the brakes, the backplate , bearings and the stub axle out of the housing. Weld the stub axle onto an off cut of scaffolding.
So we now have two wheels, spinning on the ends of two straight lengths of steel.
We take some scrap angle iron pieces and make a rectangular frame for the mill. This form as the base of our mill.
In order to make the sliding mechanism, we take a scrap pipe and try to fit it onto a square iron pipe so it can slide in and out smoothly. This will be used for all adjustments. This is welded onto the frame.
A Steel plate is welded onto the sliding bars. This is for the engine to sit on. The engine will drive one of the car wheels
We mount the 11 HP Petrol Engine to steel plate and the tire is connected directly to the engine shaft through a drive belt.
The drive wheel is bolted on to the frame ,also added a lever for the engine mount which will act as a sort of clutch, tightening and slackening the belt when necessary.
We add two more pipes on the bottom of the frame and slid them to the support platform of the second wheel made from the same square box iron and some short sections which is part of the blade guide.
The second wheel has to be adjustable in a few different directions and has to be lined up with the first wheel so the blade stays on them both without running off the tires. To adjust the tension on the blade by moving the wheel away from the first one, we use a bottle screw.
The blade guides are made from cheap bearings. They needs to be adjustable so that the saw can cope with logs of different sizes. The blade guides help keep the blade straight as it goes through the log and also stops the plate being pushed off wheels
The band saw has to go up and down so that it can cut planks from a log. We make a simple frame to hold it. It has to fit inside vertical pieces of angle iron on the saw. The support frame is bolted onto to the saw by using a bracket which grip the uprights.
Couple of barn door pulleys are bolted onto the top of the support frame and the mill frame. A trailer winch is bolted on to the middle of the support frame. Using a 3mm wire and winch-pulley system, we can move the wheel frame up and down.
Two short pipes are added at the front and these hold up a guard which can be taken off when we need to get at the belt or the blade. If the blade snaps, the side guards should make sure that it heads down towards the ground and not up to the ceiling.
The saw is stationary and the log is moved through it using dolly trailers or rails.
- How to build a simple Homemade PVC Off grid River Pump to pump water from a river or creekThis project goes over the build of a river pump that can be used to pump water from a nearby river or creek anywhere you want without any external power.It works off of a circular tube, gulping air and water as it rotates. It works by harnessing the flow of the river and creating air pressure to push the water further.It pushes water out from the river and up through your hose system, which you can direct where needed. To use a river pump, all you need is a nearby river or creek that has flowing water and a location that is deep enough to support your river pump. Here are the parts needed for this water pump: A 3 inch to 4inch reducer A 4 inch to 6 inch reducer 40 foot ,3/8 inch tubing 3 inch socket to thread /cap Garden hose adapter Quick release couplings Six,four,two inch pipes Take your angle grinder and cut them to four pieces.Connect the pieces together using a PVC cement solvent and make it into a cone that steps down as it goes. A window screen is used as a shield on the back.So this design is supposed to be rather streamlined in order to keep debris and stuff from getting caught as the pump works The cap at the end of the cone is attached to the swivel piece. It needs to be able to swivel freely on top of this. The hose tightens into this metal swivel piece and gets locked down. Next is building fan blades for the front of this pump to spin it.Cut the PVC into 4 equal blades that is 8 inches tall. Bolt the swivel piece along with the blade we have just cut. Water comes flowing in and hits the blades that is attached to the rotating swivel, makes it move and rotate and then hits the next one in line. The end piece is attached to the the PVC cone that we made earlier.Next step is getting our 40 foot hose tubing to get inside the pipe and attach to the swivel end. Next step is wrapping the 40 foot hose around the pump .We need to wrap the hose in such a way once the water hits the swivel end,the hose has got to pick up water. The Garden Hose is connected to the swivel end of the pump.Place the system along the direction the flow of the river or creek.
- How to build a Super Efficient Outdoor Wood Stove Heater from an Old Propane BottleThis project goes over the build of an efficient outdoor wood burning stove heater out of an old propane bottle and some scrap metal from the scrapyard. This stove has secondary burn system that helps in combustion of any unburned smoke or fume inside .Almost little to no smoke coming from the flue pipe. The first step is to make sure that the old propane tank is empty. We take the valve at the top by removing the valve protector cage. Fill the tank with water and let it sit for a few hours before we drain the tank and start cutting top and bottom. With the help of a hole saw cutter ,we cut 100mm four inch holes at the top and bottom of the tank . The top hole is for the flue pipe to sit in and the bottom hole is for cleaning the ashes out. We also remove the bottom stand too. Next, we cut a hole for the door for the stove. This is cut as high up to the top of the bottle . The door is made of chequered plate piece . We fit a rectangular pyrex dish glass piece in the middle of the chequered plate that can withstand high temperature with couple of steel bracket pieces. The glass on the door helps us to see how the secondary burn system is working inside the chamber. The door is attached to a frame through hinges. The flue outlet on the top the tank is attached through a flange piece with holes. The door handle is made of a socket wrench. The wrench is bolted to the plate and a small metal piece is welded onto to the frame to which the wrench is pulled to close the door A deflector plate made of small holes is installed inside the stove on the top . We drill 8mm holes around the top of tank and put dome bolts across them. The deflector pipe sits on these bolts. The deflector plate stop the unburned gases exiting out the flue outlet pipe. This encourages the flame that rises, pass through the deflector plate holes into the secondary burn chamber that helps in better combustion. The secondary burn system is made of stainless steel pipes .The air intake section is long enough to get the air coming in to get super heated and move into two sections filled with holes. Since not all gases from the wood combust from the primary air intake, the secondary burn pipe ensures that the air gets super heated before exiting the pre-drilled holes and helps burn the unburned gases rising from the fire before exiting the flue pipe. The secondary air intake pipe coming out of the firebox is welded on the top of the tank with a flange piece. The primary air intake pipe that goes under the door frame is made of a two inch coupler and threaded damper disc. A small metal piece is welded to the coupler with a hole in the middle. The damper disc screws in through the hole that allows us to close and open the intake .
- How to build a Cheap Waste oil Barrel Heater for your Garage .Generate Free Heat from Used OilThis 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.
