Invest the time to do your research and make a wise decision. A bandsaw is more versatile than it appears at first glance. The bandsaw is one of those specialty power tools that does a job that no other tool can do as well. In the case of the bandsaw that job happens to be cutting detailed and accurate curves in wood or metal. The fact of the matter is a good bandsaw has more uses than simply cutting curves. In a home shop it can be used for: resawing thin strips from larger pieces of wood ripping small pieces of stock even cutting tenons and some rabbets However once you start looking at the options you realize that there are a variety of styles and sizes available. So... how to choose the best model for your needs? Bandsaw Type These saws fall into two main categories: floor stand models (also called cabinet models) and bench top models. The floor stand models generally larger in size are what you would probably find in professional shops.
The problem then is that few consumer-grade bandsaws are strong enough to tension such a wide blade and an insufficiently-tensioned blade is likely not to give good results. You can rip perfectly well with the correct ½" blade on any bandsaw if it is set up properly on the machine. Conversely its no good expecting to be able to cut tight bends with a wide blade. If you are doing lots of curved work you will need to fit a narrow blade. A motorbike can go round a much tighter corner than a bus can! Number of teeth As a general rule you should use as few teeth as you can get away with whilst ensuring that there are at least 3 teeth in the wood. So for home woodies making furniture 3 TPI is good for ripping solid timber. Why are fewer teeth better? Because the sawdust has to have somewhere to go and it is the gullets behind the teeth that do that job. Ripping produces long curls of sawdust which have to go somewhere.

Remember the term certain distance this is important. Each molecule of steel is round in shape and can be stretched or elongated to a certain distance before it is stressed and begins to remain elongated. When a molecule remains elongated it has been distorted in the gullet from pulling too large (more than the body molecules can take) of a tooth load. The band gullet has what we call a long front. We say this because the front has stretched but the molecules at the back of the band have remained un stretched. This condition causes a hump that rises up in the middle portion of the band or in other words the middle of the band will hump toward the slab side and the mirror image is on the log side being concave. At this point the band will dive into the log every time! Note: A good spring has the ability to elongate or compress a certain or prescribed amount and return to its original shape millions of times without losing strength.
