A catalyst for this seems to be Jim Cummings article “Home Shop Bandsaw” in Fine Woodworking #63. From the hundreds of bandsaw owners I’ve talked with since the article appeared, it seems there are lingering questions on how to adjust a bandsaw blade, the blade choice and operation. “To find the correct tension, you can start with the tension scale on your saw, but you will probably need to fine tune the adjustment. With the saw unplugged, increase the tension on the blade until pushing on the side of the blade with your finger using a moderate amount of force deflects the blade about a 1/4” from its normal position. An interesting experiment is to set the side guys too far from the blade and notice how increased feed pressure and turning make the blade wander.
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.
how to adjust bandsaw blade Related Question:
Why does my bandsaw blade wander?
If the wheels are worn and do not have a distinct top to the crown then the blade will not know where to go, and may wander around. This of course can cause poor cut quality and difficulty in setting the guides.
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.
Where should a bandsaw blade sit on the wheel?
Make sure the machine is disconnected from the power supply. When tracking, you always want to make sure that the blade is sat on the crown of the wheel, with the deepest part of the gullet in the centre.
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 do I get my bandsaw to 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 burn the wood?
A majority of issues with wood burning is because of a dull saw blade. These blades may not be sharp enough to efficiently cut the wood, and thus create enough friction to heat and burn the wood. What is this? Dull blades make it more challenging to cut, which causes friction as you pass the wood through.
How tight should a sawmill blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
How tight should a bandsaw 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. blade, I would set the scale to 1/2 in.
Why is it important to adjust the height of the blade guard on the bandsaw?
Adjust blade guard height to about 3 mm or 1/8 inch to 6mm or 1/4 inch above the top of the material being cut. Wider gaps will place tension on the blade and increase the risk of breaking. Ensure the blade is tracking correctly and runs freely in and against the upper and lower guide rollers.
What is the gullet on a bandsaw blade?
Bandsaw blade gullets are the space or curvature between each individual tooth on a saw blade. With each pass of the blade, the material being cut will curl into the gullet, creating a spiral of material called the chip. Too many teeth in the cut will make the gullet full.
Why does my bandsaw bounce?
A lack of straightness in either the blade or weld could be causing the blade to bounce. Next, it is important to check the blade tension and make sure that it is high enough to keep blade bounce to a minimum. That way, your blade won?t take as much damage.
Why are my bandsaw cuts wavy?
The clasic cause for wavy lumber is pushing a dull blade past it’s limits. Sharp don’t get it.
Is it worth it to sharpen bandsaw blades?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How many times can a bandsaw blade be sharpened?
It often makes sense to replace a dull blade with a new one, but you can sometimes get the best value out of merely sharpening an old blade instead of replacing it altogether. You should typically be able to get two to three sharpenings before you need to change your blade completely.
How long do bandsaw blades 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.
