For instance will you load the logs yourself or will you need a hydraulic loader to do it for you? The most popular sort of portable sawmill is the bandsaw mill. One advantage that bandsaw mills have over circular mills is that you will get at least 20% more lumber from a band mill due to the mill turning less of the lumber into sawdust. These mills range significantly in size and cost. Here are a few things to consider about the major varieties: If youre a hobbyist who wont be milling every day consider a manual saw. These are the least expensive. However they may also be too small for your needs and may not have enough power to cut larger logs. A manual saw will come with few extras but may be purchased for around $10000 or even less. For a few thousand dollars more you can get a mill that will include some labor-saving features though you will still have to load the logs manually. For those who want to mill logs much more regularly a fully hydraulic mill is much easier to use and requires less effort from the operator. The main downside is cost -- a new fully hydraulic band mill may cost over $20000 or even over $30000.
Tension: Adequate blade tension reduces the blades tendency to lead erratically under thrust. I have found that the standard tension gauge is not accurate. It is better to use a little more tension than indicated. You can check it by opening up the thrust bearings and lateral guides. Back off both above and below the table so they do not contact the blade. Crank the tension gauge to the desired setting. Give the blade a sideways nudge about halfway between the upper and lower wheels. The blade will deflect easily for a short distance. This sideways movement should be 1/4". If you push harder it will bend farther but there is a distinct point where it quits deflecting easily. If you can deflect more than 1/4" then add tension until this deflection is 1/4". Stock Control: How does one cut straight lines? Answer: find out how the saw wants to do it and do it that way.

Of course your budget will eventually dictate the decision to buy. The size of bandsaws Bandsaws are generally grouped by size. Woodworkers often mistakenly assume that the stated size refers to the throat capacity (blade to frame) of a given machine. This is not correct as the throat capacity is normally very close to the wheel diameter which does not determine their size. Blade capacity of bandsaws varies and is an important consideration as it dictates to a certain extent what a woodworker can cut. The narrowest blades on a bandsaw will allow for very fine and intricate cutting while others slightly wider will cut graceful shapes easily. The wider the blade the easier it is to cut straight as the blades have the tendency to twist while performing the cutting action. Bandsaws that suit your business The smallest bandsaws are designed for benchtops and are usually in the range of 8". These are lightweight compact and designed for light work.
