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.
how to adjust the blade on a bandsaw Related Question:
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.
Why does my bandsaw cut to the right?
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 wander?
The crown of the bandsaw wheels is what keeps the blade in place. The blade will always try to climb to the highest point of the wheel, the top of the crown. 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.
Is it worth sharpening 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.
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?
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..
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.
How many teeth per inch should a bandsaw blade have?
The general rule of thumb is: For wood and soft materials aim for 3 – 6 teeth in the workpiece. For metals and harder materials aim for 6 – 24 teeth in the workpiece.
