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.
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.
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.
