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.
This in turn causes the blade to not cut in a straight line. With a dull blade, there is an expectation for it to cut slower and cut crooked. The main thing that normally goes out is the crown, which is what is holding the blade in place, Most of the time the blade is right at the center, but if the crown begins to wear out, it may start allowing more and more movement, causing the blade to not cut in a straight line.
I resawed some 5 inch cherry with a 1/2 inch 4tpi blade and while it cut pretty straight the cut was even rougher. Another result from the set on the teeth is that the cut is not as smooth as, say, a carbide tablesaw blade. 11-21-2007, 8:37 AM #3 I suspect your bandsaw can’t tension the blade enough to cut even 4″ material.
Learn how to choose the right bandsaw blade to create smooth cuts every time. Use blades with more teeth to create cleaner cuts and blades with fewer teeth for faster cuts. Knowing how to setup your bandsaw and selecting the best blade will help ensure you create smooth, clean cuts.
band saw not cutting smooth Related Question:
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.
Why does bandsaw not cut straight?
Bandsaw Wheels Aligned Incorrectly or Worn High-speed machines generally have a crown or rounded surface on the blade support wheels, the same way a bicycle tire has a round cross-section. The blade should run at or near the center of the crown and not excessively close to the front or rear edge of the wheel.
How much tension should a bandsaw 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.
Can a band saw cut curves?
Whether it’s a tight curve or a closed opening, you can cut it on your band saw with a couple of easy tricks. Cutting on the band saw can be the same thing. The narrower the blade, the tighter the spots you can cut; in fact, some band saw blades rival a scroll saw for cutting tight curves.
How long does it take to get a WoodMizer sawmill?
And demand is high. “The lead time is 44 to 59 weeks right now for a sawmill,” says Kate Sebring, a sales representative for WoodMizer.
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.
Why do bandsaw blades break?
Machine Defects Even the best blades can fail if there is something else wrong with your bandsaw, and even a small misalignment of bearings or guides can put a twist in the blade as it goes around. Resulting in tension being applied in all the wrong ways which will lead to early breakage.
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.
Will a bandsaw cut 2×4?
your “small” tablesaw is one of the finest in the portable table saw category and should have no problems resawing a 2×4 although you may want to finish the cut with a jig saw by setting the blade slightly less than half the thickness of the 2×4.
How thick can a band saw cut?
Band saws are the undisputed champ when it comes to cutting curves and slicing through thick material. Many small band saws can slice though lumber a full four inches thick, and bigger saws handle six-inch cuts.
Which side of the line should you always make cuts on?
Always cut to the outside of your mark line because you will have to round off your edges regardless. For thinner wood, a jigsaw can provide better results.
What do you use a deep cut band saw for?
The Deep Cut Band Saw has one basic purpose: making clean, straight cuts—and it does this very well. Since I first used the saw to cut steel bar stock, I’ve also cut steel and PVC pipe, steel tubing, conduit, and aluminum bar stock.
