On a typical wood or metal cutting blade the hook or of point of the blade should be pointing down for a vertical blade bandsaw, or for a horizontal blade saw the hook of the teeth should be pointed such that they enter the workpiece first as the blade moves. During regular cutting on a well set up bandsaw the blade will move or bow backwards a bit as you press the workpiece into it. The side guides will assist in keeping the blade cutting straight, but they are not an iron lock on the blade forcing it to cut straight.
Squaring everything up, the blade starts to wander around the 15″ mark, but only the top half of the blade wanders as the bottom is still spot-on the mark, so in effect the top half of the blade is twisting in the wood. 02-09-2011, 6:27 PM #4 I’d suggest a more substantial blade in terms of blade width. 02-10-2011, 1:19 PM #11 I can resaw just as well with a 3/8 blade as a 3/4. You just have to slow down and let the teeth cut.
how to keep bandsaw blade from twisting Related Question:
Why is my bandsaw blade twisting?
The difference between the steak and the bandsaw is where the steak knife is short and thick, the bandsaw blade is generally long and skinny. This becomes a problem because it is possible to push hard enough on the blade to cause it to twist left or right.
Why is my band saw not cutting 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.
What causes bandsaw 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.
Which way should the teeth face on a bandsaw?
Installing A Bandsaw Blade Make sure the teeth point downward.
Why does my bandsaw spark?
Ceramics can cause sparks. Or, if your thrust bearing is too far past the blade, more toward the center of the bearing than the edge, then it won’t turn and you’ll get sparks too, and possibly wear a groove in the bearing.
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 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.
How tight should 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 my bandsaw burning 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.
Can a bandsaw blade be turned inside out?
Re: Turning a band blade inside out hi ,just get heavy gloves,an uncoiled blade ,step on the bottom and turn the blade inside out,and it will go right on a turner mill and just reverse the blade to sharpen. Thanks.
