When it comes to using a portable sawmill your choice comes down to one of two options: either a bandsaw mill or a chainsaw mill. When considering a bandsaw you have to weigh all of the evidence to decide if it is the best choice for your needs. Bandsaw mills work by means of a blade sliding back and forth horizontally through the lumber. The denser the wood the harder it is for the blade to move. If a blade gets too slow or starts to bind then you wont have a precise cut. The blade has to fight to get through the wood and will start to bend slightly. Plus you run the risk of burning up the motor. The only way around this is to increase the power. Thats why it is better to invest in larger models of bandsaws. If you choose to continue using a bandsaw that is too small for the job then you could end up with wavy cut wood.
In the case of woodworking bandsaws variable speed is not usually an issue. However when cutting hard plastic or metal having a lower speed available can be a good feature. Additional Features All bandsaws have tables. The table is the large flat surface that supports the wood when you are using the saw. The table should be cast-iron steel or aluminum alloy and ideally should be capable of tilting generally up to 45-degrees for angled cuts. In many instances the table will measure about 16" square and in the best of all possible worlds would have a miter track as part of its standard equipment. Maintenance Issues Because there are so many moving parts in a bandsaw it is important to keep those parts as clean as possible for smooth movement and accuracy.

See that the fence as well the blade are at 90-degree to table. Choose a section of straight wood of up to three feet length. Draw a line in the center. Cut by hand down the line while maintaining the cut along the center line. Keep feeding at the usual speed. Once you get it straight clutch the wooden peace on the table. Switch off the machine. You already got the desired lead angle of this blade! Using a pencil draw a line straight on the table of bandsaw along the length of wood. With the help of a wrench loosen the bolts on the fence. Adjust angle on the fence alongside the pencil mark of the cut. Tighten the bolts. Now the fence is ready for the right lead angle of your blade. It delivers straight cuts. Fix it once once and keep going.
