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.
Similarly you must adjust the upper block guides in their forward-back positions centering them to the center of the blades width. In their left-right positions adjust the guide blocks to only faintly touch the blade. Adjust the lower blade guides in the same manner. Testing: And at that your bandsaw blade removal and reinstallation is almost complete. The last step of the procedure is simply testing the sucker out. Plug-in and engage your bandsaw. Observe the blade - ensure it doesnt vibrate or fall out of center. In the event the blade does vibrate or fall out of center simply re-tension and re-track the blade until it spins properly. Im often asked what sort of blades I use on my bandsaw. And the answer is - it depends.

Carefully recoil the blade and tie it off to prevent the thing from becoming an explosive blade disaster. Making Friends With Your New Blade: Opening your new bandsaw blade can also become an explosive blade disaster.
These can cut 6" deep timber without any trouble and will resaw up to 12" deep but this would mean pushing maximum capacity. While these machines come with plenty of added features such as rack and pinion table tilt rack and pinion table tilt look for quick release blade tension levers. This is a very useful feature. It allows you to simply knock off the bandsaw to detension when you pack it in at the end of a long day and then swing it back to regain the same tension it was left at previously.
