How much tension should a bandsaw blade be?

Finding the right tension Most blade manufacturers recommend 15,000 psi to 20,000 psi for a common carbon-steel blade. However, bimetal, spring-steel, and carbide-tipped blades are much stronger than carbon-steel blades, so manufacturers recommend a much higher tension: 25,000 psi to 30,000 psi.

How do you tension a timber wolf bandsaw blade?

Start the motor or engine on your saw and bring the blade to full cutting speed. Allow the blade to run for approximately 30 seconds. Once you are satisfied that the blade is stable on the band saw wheels at full speed, very slowly reduce the tension on the blade while watching the blade between the wheels.

Should I release tension bandsaw blade?

Release blade tension when not in use. That helps prevent blade stretching and deforming the band saw tires, which are likely made of rubber or urethane. A stretched blade will cause the operator to increase blade tension to compensate, increasing blade break risk.

Why does my bandsaw not cut straight?

Band Saw: Not cutting 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. Using too much force when feeding the work piece through the cutting area can cause the band saw blade to twist and cut the piece crookedly.

Why did my bandsaw blade snap?

Bandsaw blades will break if you force timber into it, apply too much or too little tension, you use the wrong type of blade for the cut, the blade tooth pitch is incorrect, the blade is installed incorrectly, the thrust bearings are not adjusted, the blade is blunt, the blade has a faulty weld, you are cutting too …

Can a bandsaw blade stretch?

Every 0.001″ of blade stretch is equal to 5,800 psi of tension over 5″ of blade. When resawing, blade manufacturers recommend a blade tension of 15,000 psi. The wider the blade, the more force will be required by your bandsaw tension spring to reach the amount of stretch required for 15,000 psi of tension.

Does a bandsaw cut straight?

Just like other power saws, a band saw blade needs tension to produce consistently accurate and straight cuts. This is especially so for thicker slabs and denser woods. Bandsaw blade manufacturers recommend a tension of between 15,000 PSI (pounds per square inch) and 20,000 PSI for a typical carbon-steel blade.

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.

What happens when a bandsaw blade breaks?

Band Saw Blade Break-In Procedures When new, the teeth are just too sharp. Cutting at full rate will cause fracturing of the feather edges, which will lead to premature blade failure. Breaking in a band saw blade wears off this ultra sharp edge and allows the blade to retain its cutting ability longer.

What kind of blades do timber wolf bandsaws use?

These blades are thin kerf, low tension, and made from Swedish silicon steel. It’s easier for your saw to push a thin kerf blade through a cut than a standard kerf blade. At .025″, Timber Wolf blades are about 25% narrower than most other band saw blades.

How much tension do you put on a timber wolf blade?

Add another 10% of tension to the blade by turning the screw-tensioner approximately 1/8 to 1/4 turn. The “flutter test” is now complete and you are now at appropriate tension for that particular blade.

What are the benefits of a timber wolf saw?

The benefits are: more power, because your saw is not working as hard, less wear and tear on your saw, tighter turning radii with a given blade, and longer lasting blades. And no, you can’t run just any blade under less tension and try to get the same performance as the Timber Wolf blades.
