I’m trying to figure out my band saw. I’ve been told “get better blades” Will do. I filed the back of the current blade. Changed the tension, checked out the video that is pretty comprehensive about tuning it up.

Raised the guide yesterday while cutting some 6 inch fir to trim it down. 1/4 inch each side. @ 6 tpi blade.

Now I’m getting a sort of grinding noise from the upper wheel.

Before I take it apart…SIGH I’m looking for more suggestions.

Thanks

i think i remember someone talking about one of the two bearings on the top wheel went out on theres. so it might not be a major thing if its just a bearing and you check it out before it gets real bad.

Possible blade gaurd,guide or guide blocks touching anything moving when you raised the height? Blade off, still noisy when spun by hand?

Thanks,

Will release tension, remove blade, and check for noise. Blade gard was also contributing.

My first thought was blade guard, but have you checked your guides blade guides top and bottom to see if they are properly adjusted/tightened (sometimes they get loose from vibration. They could be too tight or the blade might be hitting one of the guides

My cover rubs on the upper wheel of my grizzly. Couple of washers over the bolts cured the issue.

The other suggestions are good ,I hope it’s not a bearing,have you been releasing the tension on the blade when not in use? I hope it’s a minor adjustment of the guard.

I usually use compressed air to blow my saw(grizz 555X) down every couple of months. Maybe you got some saw dust where it’s causing a problem.(If you don’t have a compressor just buy a can at the local computer store)

With the blade tensioned spin by hand, if you are getting the grinding sound, using the tracking knob move the blade a smidge to the outside of the top wheel. Grinding stop? Getting the deepest part of the gullet to the middle of the wheel on my saw, will get the grind; it is the wheel rubbing against the cover.

My blade guard will rub on my upper wheel when raised all the way. Loosen those 2 screws that hold the blade guard and straighten it up to where it misses the wheel.

That would be the best and simplest explanation for the noise. I doubt you have a bad bearing as the problem didn’t occur until you raised the guides/guard.

Good luck and keep us posted.

Back in from shop.

Took the saw blade off the top wheel, rotated. No sound! Opened upper and lower doors for inspection. When I had put the blade back on upper tire the bottom was off. Aligned the bearing guides for the blade.

Re set the upper blade guard. Even sprayed silicon lube in bushing area.

Total noise was significantly reduced Metal on metal grinding sound gone!

New question? the video on YouTube suggests an 1/8 inch play in the band saw blade?

What I did was test cut with miter gauge. Made sure the gauge was square to the table. Had to keep increasing tension til I was not getting movement to the right during the test cuts?

How much is the correct tension?

Still seeing pulsing in the blade as it slows down?

Thanks for all the great suggestions. Pumped me up to work in my HOT SHOP today!

LOL

Ops have to release the tension when I go out to feed my cats.
