How do I know if my bandsaw blade is dull?
Also asked, how do I know if my knife is dull?
The blade feels dull. Gently run your fingertips over the edge of the blade. Sharp knives simply feel sharp, with a blade that has a well-defined, distinct edge. On the other hand, if the blade feels dull or rounded, you're knife will benefit from being sharpened.
Also Know, how long does a band saw blade last? Bi-metal and carbide are the best choices for re-saw which is very hard on the teeth in hardwood and the thicker the stock the quicker it dulls. But.. with that said even carbide which will last about 10 times longer or bi-metal which last about 5 time longer for re-saw won't stay sharp forever.
Secondly, how tight should my bandsaw blade 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 knife dull?
#7: Using It Dull A dull knife will require more pressure to get through your food. More pressure means a higher chance of slipping and accidentally cutting yourself. More pressure also means that any accidents are likely to be much worse than the small nick you'd get from a sharp knife that's used gently.
