05.07.2020Make sure tire surfaces are in good condition—they cannot be hard, flattened out, cracked or brittle. On mills with loose fitting V-belts, replace them with the next size down so they are tight fitting. Mount the blade on the machine and apply the tension to the band that the manufacturer recommends for other steels. Close all covers for safety purposes. Start the machine, engage the clutch into the high speed cutting mode. NOTE: You will not be are timber wolf blades good vision any wood.
Stand at the head of the machine, with your hand on the turn screw tensioner and your eyes on the band saw blade. Very slowly start detensioning by half turns at a time, keeping your eyes on the band saw blade. The object is to bring the tension of the blade down to a point that the blade starts to flutter. At this point ADD one-eight to one-quarter turn of tension. You have now are timber wolf blades good vision our blade correctly.
Shut off the machine and put your guides back in place. You are now ready to start sawing. Since you do not know exactly where the proper tension is, it will be easier to remember if you take off 8, 9, or 10 full turns of tension until the band is completely relaxed.
The next time you use our bands, add the same amount of turns of tension that were taken off. At this point, you will only have to run the flutter test one time. Run the same test as above.
With hydraulic tension you need to detension lbs. After you have removed the flutter, add an extra 50 lbs. Remember the pressure on your gauge. The next time you use our band, tension it to the same setting you found after running the flutter test. With air bag tension, you need to detension 15 lbs. After you have removed the flutter, add an extra 15 lbs.
With the air bag tension you usually have a gauge and you will know exactly where low tension is by reading the gauge. This prematurely destroys the body of the band and its gullets. It also dry rots are timber wolf blades good vision tires or V-belts. Apply the solution with a spray bottle to BOTH sides of the band about once every four minutes, while the machine is running.
I guarantee you will be amazed! Are timber wolf blades good vision life; No pitch buildup; No rusted or pitted bands! A great delivery system is the 12 volt windshield washer assembly out of an old car! Unplug the machine. Spray Pam vegetable shortening on a rag and wipe on both sides of the blade while turning the upper wheel by hand. Applied sparinglyyou can cut grade lumber with NO staining to your product. When you are done cutting are timber wolf blades good vision the day, take the tension off your blade.
Band saw blades, when warmed up from cutting, always stretch; and upon are timber wolf blades good vision shrink by tens of thousandths of an inch each cooling period. Therefore, blades, when left on the saw over tension themselves and leave the memory of the two wheels in the steel of the band, which will cause cracking in the gullet. When you leave the band on your saw under tension, not only do you distort the crown and flatten out the tires which makes them very hardbut you also place undue stress on your bearings and shafts.
Believe it or not; you can, and will damage your wheel geometry sooner or later and considerably shorten bearing life. You are also crushing your tires or V-belts. If you are running too much set for the mass or thickness of the wood, you have too much air and not enough saw dust.
This is the most damaging thing you can do to a are timber wolf blades good vision. You will have short cutting times and premature band breakage.
The saw dust should be warm to the touchnot hot or cold. Because of our deep gullets, we are able to use lower hook angles which generate less heat on the tip of the tooth.
If you are cutting very hard wood like white oak, walnut, ash or anything frozen throughout, the blade will probably rise in the cut. This is called push-off. The hook angle must be brought back to 8 degrees. You need to use an 8 degree hook angle for hard knots. On the other hand, if you use a 12 degree hook angle on very hard wood, the tooth skips over the hard surface because the tip of the tooth is pointing too far forward.
Having a 12 degree hook angle in hardwood are timber wolf blades good vision causes push-off making the band ride up. The band locks itself in place, cuts straight across, and drops down at the end of the cut. This also burns up the band and over tensions it. By articulating the proper hook angle, and having your are timber wolf blades good vision mathematically correct for the pitch, you will achieve straight grade cuts every time.
We manufacture for North America 5 appropriate sets with a 10 degree hook angle. WARNING : Again just as I have brought to your attention the short life of a dial indicator, you are also trusting the templates and gauges on your band saw blade sharpeners. They are hardly set at the exact angle that you think they are. The machines themselves wear out. The pins and the guides in the sharpener that the back of the band rides on, wear out. To give you an idea of the amount of wear your sharpener will receive, think of this.
Your band, if 14 ft. You have sharpened 50 bands. How do you determine if your hook angle is right, and see it. Without it, you are blind and will never be able to articulate a band saw blade.
Without a protractor, you are assuming the hook angles are right. I have analyzed over 4, band saw blades since Over half of the problems, were due to assuming the hook angle was right on.
You must have one. You MUST maintain gullet integrity. The gullet is NOT a trash can or dumpster for the saw dust. In fact, it is the second hardest working part of the band. A well defined gullet is like the inverted wing of an aircraft. It is responsible for the forced air flow, cooling the steel and removal of the saw dust.
If you are running appropriate set, the air is driven through the log by the gullet at the speed of the band. Are timber wolf blades good vision causes the saw dust to be sucked out of the cut. The saw dust effectively cools the gullet by spinning around the inside and spilling over the back side of the next tooth. Are timber wolf blades good vision you sharpen just the face and the back side of the tooth, you ruin the gullet integrity and destroy the performance of the band.
Less expensive brittle steel not only welds harder but must be highly tensioned, thus decreasing overall run time no matter what you do.
It is the highway for proper air flow, causing the cooling of the band and chip removal. By the way, always keep a 10 degree hook angle. NO more, NO less for good general sawing. Very hard, frozen or knotty wood uses an 8 degree hook angle. We include a schematic. When all is said and done, the band saw, in all its shapes and sizes, is a fundamental machine.
But, as you have just read, there is a lot to know in becoming the master of your machine. A band saw blade is a tool. You must lubricate both sides!
