Install the blade and apply just enough tension to keep the blade securely on the wheels. Instead, tension the blade until your finger is only able to deflect the blade by about 1/4″. This test should be done at the back of the saw where nothing can get in the way of the blade. Adjust the thrust bearings carefully so that they do NOT rotate while the blade moves, but they DO begin to rotate as soon as light pressure is applied to the blade.
Even a low-end bandsaw blade tension meter can cost $300. If you use your bandsaw a lot or are doing delicate work, having the proper tension on the blade can be critical and the only way to accomplish this is with a bandsaw blade tension meter. With the bandsaw blade properly installed, and tensioned, and the blade guides properly set, the next issue is to make sure that the bandsaw table is square and level. We suggest that you go through the setup steps in this how to set up a bandsaw properly: the ultimate g guide before starting a new project and each time you change your bandsaw blade.
The first thing you need to do is install the blade. Remember, do not push too hard but rather adjust the amount of pressure and monitor the blade tracking. A known fact is if the blade slides in the cut slot easily, the table is 90 degrees to the blade.
A bandsaw will only cut accurately if the blade guides are set correctly, so these are important. Some people have the bearings touching, others don’t, we tend to side with the latter and like them to be set around 0.5mm either side of the blade. Simply place the Buddy up against the blade, using the recess to counter the tooth set.
The band saw set up is to carefully install and align the blade. So being aware of how to set up the blade tension should be your priority step in bandsaw set up process. If the side guides come to contact with the blade or set at the parallel position to the blade teeth then the blade can be broken when it moves.
Whether you’re a beginner or could just use a refresher, we’re going to walk you through the process for a perfect bandsaw blade adjustment setup every time, no matter what blade you install. Lower the upper blade guide, open the wheel housing(s) and blade guard and carefully remove the blade. So it should be no real shocker that you’ll encounter conflicting schools of thought regarding blade placement on the wheels and how it affects blade “Drift”.
Use paper to adjust the side roller clearance with the blade set just behind the gullet of the blade and have about two millimeters between the rear of the blade and the thrust bearing. You will end up with a range of blades likely ranging from 6 mpm to 25 mpm with 1.5 T.P.I to 12 T.P.I. The larger blades with smaller T.P.I are used for large and deep cutting on dense woods. When setting up the blade, the top wheel can be adjusted to allow for the blade to center on the wheel for correct travel by cantering the wheel in or out at the top for centering the blade.
how to set up a bandsaw Related Question:
How tight should my bandsaw blade be?
The blade should deflect no more than 1/4 in. A good place to begin is to tension the blade until the meter reads proper tension for the next wider blade. For example, if you’re tensioning a 3/8-in.
Why won’t my bandsaw cut straight?
Band Saw: Why won’t my band saw cut straight? When the band saw cuts crooked, a dull blade, improper feeding, loose blade tension or not using a work piece guide could be the cause. Use the rip fence or miter gauge to guide the work piece uniformly through the cutting blade to make straight cuts.
Why does my bandsaw blade keeps coming off?
Blade Tension Is Too Loose The most common reason why the blade is slipping off is that there isn’t enough tension to keep it on. Blades can slowly become loose after years of wear and tear, and eventually, you’ll need to tighten or replace them.
How is a band saw properly used?
A band saw can be used to cut curves, even in thick lumber, such as in creating cabriole legs, to rip lumber and to crosscut short pieces. The most common use for the band saw, however, is in cutting irregular shapes. The second most common use is in resawing or ripping lumber into thinner slabs.
What materials can a bandsaw cut?
Most bandsaws have two wheels rotating in the same plane, one of which is powered. The blade itself can come in a variety of sizes and tooth pitch (teeth per inch, or TPI) which enables the machine to be highly versatile and able to cut a wide variety of materials including wood, metal and plastic.
How far should the safety guard be above the stock?
Keep guards in place at all times. The blade guard should be from 1/8 to ¼ inch above stock. Keep hands away from blade and do not open upper or lower bandsaw doors while blade is in motion.
Why are my bandsaw cuts wavy?
Re: Band saw Cutting Wavy Cuts. The clasic cause for wavy lumber is pushing a dull blade past it’s limits. Sharp don’t get it. On these low powered mills, the blade gotta be razor sharp..
What causes bandsaw blade drift?
Drift is cause because the blade buckles under the load. You can see that by stretching a ribbon between 2 points and applying a pressure to one of the edges, it will turn sideway easily. A sharp blade and high blade speed will help a lot with that.
Can you put a bandsaw blade on upside down?
Typical bandsaw blades can be flipped “inside out” to make the teeth point the other direction. On some knife edge style blades and grit edge blades you can get a fresh sharp cutting edge from a blade this way, just by flipping it inside out.
Why does my bandsaw blade wobble?
The blade on a saw left idle for long periods of time can leave an impression in the rubber tire which might cause erratic tracking. Purchase and install aftermarket replacement tires. (Search for “bandsaw tire” at woodcraft.com.) If you still see a back-and-forth motion, the culprit is probably the wheel itself.
How long should a bandsaw blade last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
What is the set on a bandsaw blade?
The pattern of tooth setting is “left/right/straight,” where the left and right teeth are for opening or cutting the material, and the straight one – the so-called raker tooth – is for removing sawdust from the timber. The recommended tooth-set values are different for each blade type and profile.
Why won’t my bandsaw cut metal?
Band saws are not suitable for cutting very thin sheet metal; a rule of thumb suggests the metal to be cut should be thicker than the depth of 3 band saw blade teeth, however they are excellent for cutting thin walled profiles such as box and angle.
