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.

We use three AGM batteries, and they're about 245 amp hours each.Marine or deep cycle batteries also work. Dont get a car battery.Make sure that the batteries are about same age or they start bringing each other down. The wires are connected through the positive ports and negative ports of each batteries. The positive from the inverter is connected to the positive of the first battery .Negative from the inverter is connected to the negative of the 3rd battery. The battery chargers are from Pros Series DSR.It ramps up the optimum charging voltage. https://www.youtube.com/watch?v=Zxvo3t898xI
