if the noise you`re hearing isn`t a metal on metal or bearing noise i`d just ignore it....depending on the blade and wood sometimes a bandsaw will make some awfull noises........especially if you do like me and keep pushing a dull blade `cause you`re either too lazy or too cheap to change it
lookin` at the pic vaughn linked to i`d say you`ve got a good saw that`ll push a dull blade with no problem....for thinner stuff (less than 6-8") just keep using it untill the cut quality suffers or it breaks....bandsaw blades are like drill bits and router bits, they can be sharpened, but why? new ones are usually less money than sharpening if you figure traveling to the sharpener to drop `em off and then pick `em up.....blades for my 16" saw are 11 bucks u.s.delivered to my door.
