This projects goes over the build of a cheap homemade lumber mill using materials around your home
This mill has a 12 inch saw blade purchased from Home Depot that cab do cross cuts, or it can do longitudinal rip cut.I am gonna be cutting the long direction on the word.
First step is building the rollers. Four rollers are made out scrap materials lying around. The wheels are made of polycarbonate material .These are adjusted on a drill to ensure that they roll smoothly on the pipes.
Next step is the build the tracks.Here I use 2 old steel pipes and welded to make a long one. 3 more pipes are welded on top of those 2 long pipes horizontally to give stability. Make sure the pipes are all lined up .
2 rolling carts are made from the leftover pipes tha slides across the pipes.Make sure these are parallel to each other.4 sliding pipes are bolted on these carts.
4 pieces of pipes are welded on top of these rolling pipes that are paralled to the horizontal pipes below .They act as a crank that can pull the sliding pipes.
Threaded holes are put along the pipe that connects the sliding pipes.2 cables are connected in opposite ways to a small spring pulley system that can help sliding pipes move vertically up and down when the top crank is rotated.
The Saw Blade is attached to a steel rod.The blade is attached to a washer on the other side to ensure it doesn’t fly off.
The axle is passed through a square metal box which is bolted using a bearing on both sides.
The motors attaches to the top of the box mount .A pulley is then attached to the metal rod from the motor using a small wheel.
The next step is to take whole side assembly thing attach it to the cart so it can pivot.
Ball bearings are attached to the box on both sides.This must be placed at a very specific distance away from the blade. So that when I flip it the the edge of the blade will line up so it cuts clean without cutting deeper into the wood and without not cutting far enough and leaving it still attached.When its swiveled it will pivot the blade perfectly.
Next step is make take the whole motor and blade assembly and attach it to our rails so that it can slide and rotate .
We attached 2 pieces on both sides of the motor blade assembly to ensure that the system stays perfectly straight while cutting horizontal or vertical.

- How to build your own DIY off grid / grid down Solar Power Back up system from scratchThis project goes over the build of a Solar Power Grid Down Backup System to generate your own alternative power.A great way to utilize renewable energy as a backup source of power. Whatever may be the reason , may be to offset electricity bills or for self reliance to provide when the grid goes down, a solar backup system is simply a great way to provide alternative power to maintain a lifestyle of reasonable convenience. If the grid should go down, I can have a freezer, power lighting, pump water, maintain communications, use tools, and charge every little device I have from flashlights to kindles. This Off grid Solar Power System is composed of 5 components. Solar panels to generate the power, a charge controller to charge the batteries, the batteries to store the energy, the inverter to provide AC to the household items you wish to power. Also you need a Kilowatt meter. The kilowatt meter measures two things you have to know how much energy your devices draw at any given moment, and how much power they consume over time. Here we use 100 watt monocrystalline panels, a 40 amp MPPT charge controller, a 1000 watt pure sine wave inverter and to store the energy, 446 volt golf cart batteries totaling 470 amp hours. First you need to size your system by figuring out how many devices you are going to want to run at the same time. This will determine the size of your inverter, the inverters function is to take DC power from the batteries and converted to AC power for use with household appliances. If I have 1000 watt inverter, this means I can run up to 1000 watts worth of devices at the same time. Once you have evaluated every device that you feel that you are going to need, should the grid go down, you are gonna have a good idea of how much power you need to generate each day. The battery bank consists of four, six volt, Duracell SLIGC 125, golf cart batteries connected in series. Golf cart batteries are designed to deliver a lower amount of power over a longer period of time and then recharge quickly. When picking a spot to locate your panels, you have to consider that the sun will be lower towards the horizon in the winter, and closer to directly overhead in the summer. Building a system that actually tracks the sun would be best as the panels are always pointed directly at the sun. Also mount your panels as close as possible to the batteries. This is because the longer your wire run, the more energy is wasted due to resistance. You also need to select the proper gauge wire to transmit the power from the solar panels to the batteries. Between the panels and the batteries is the charge controller ,it controls the charge of the batteries and make sure that the batteries get the proper voltage that they need and that they don't get overcharged. Here we use an MPPT Solar Charge controller. If your solar panels are wired in series and connected to an MPPT charge controller, the voltage adds up ,thus giving us enough voltage to charge the batteries. An MPPT charge controller can charge your batteries nearly the entire time The sun is out. If your panels are far away and you want to save money and wiring, then the MPPT charge controller is way more efficient than PWM. The first step in making your solar system safe is making sure that there's an automatic and a manual way to disconnect power in each segment of the system. Starting right here at the battery box we have a 300 amp manual switch to kill the power from the batteries to the inverter as well as a 200 amp fuse that will blow automatically. Another component to the safety is the grounding. Grounding your system is quite easy to do. So get an eight foot grounding rod and drive it into the ground. Then pick up some copper grounding wire, some lugs and connect the frames have all the panels in any metal components in the system including the charge controller and the inverter.
