Ryobi band saw blade does not cut straight

The problem might be blade drift, feed & speed rates. Are you using a fence? Do you have a good blade? I had pretty good luck with my Haltbar blades of www.sawblade.com . Does your blade track properly? Check this blog site . This might help too.

clean dust off the wheels, center the blade get it tracking and tension it so it has a medium high to (wide blade) high pitch (narrow blade) twang like a guitar sting when plucked with the saw turned off

All band saws do this to some extent, but here are some things to consider
1. The tension may be too low, so that it deflects excessively when you put a little pressure on it.
2. You may be using a blade with too fine teeth for the thickness of material you are cutting. The more teeth that are cutting at the same time, the harder you have to push to get them to cut.
3. You may have a dull or poor quality blade.

Replace guide blocks and increase blade tension

Check and see if one of the guides is out of alignment or if the blade is worn. Either one can cause the problem since you already checked the tension and guides. If the guides are worn they won't hold the blade true.

Hi,
It sounds as though you may be cutting too quickly. Try decreasing the pressure you are applying to the wood.
You could also try tightening the blade more, until it PINGS when you flick it with your finger.(When it's stationary of course)
I'm assuming your guides are adjusted correctly.

this is usually caused by a dull blade or you need to carefully re-adjust the blade guides

cut freehand. A bandsaw blade will always run off to one side or the other, even using a fence.

The rip fence is intended for re-sawing only, and very thin strips

I do a lot of resawing with mine and I have found that a 3/8" wide blade gives me nice straight cuts.

The tension on the blade. the position of the guide rollers, and the condition of the blade are all important to get a straight cut. You might want to try lowering the guide rollers down close to the wood being cut. good luck.
