I have a relatively new Grizzly 1/4” 6 TPI blade on my bandsaw. I was cutting some 2” thick basswood and all of a sudden the saw made some noise and the cut quality really tanked. I took a careful look at the blade and it turns out the blade kinked a little in one spot. This means the blade travels smoothly except where the kink goes on and off the wheel and the kerf is now wider because of the kink. Is there any way to fix this, or do I need a new blade? I tried taking some pliers to it, but to no real avail. Thanks for any input.

I’ve had that happen, and I’ve never found a way to fix it… I have the blade saved for doing rough cuts if I need it, but for the most part blades are cheap so I bought a new one.

Greetings Ripthorn,

I’d say s.c that blade and get you some GOOD saw blades…...Those blades they put on at the factory are
cheap-made and of low quality… They just won’t hold up long, as you found out….Get yourself a couple of
Timberwolfs, or good blades along that line…..You’ll be glad you did…..

I’m with Rick and Dahlgren … you could try to take the kink out (with a hammer on an anvil), but all you’ll wind up with is a low-quality blade that has been weakened and may be dangerous. Most of the time when a blade breaks it just sounds like a corn sheller, but you could wind up injuring your hands, etc.

Personally, I am a fan of the Wood Slicer blades (from Highland Woodworking in Atlanta), but Timberwolf gets a lot of good reviews. Either is better than the blade your saw came with.

Throw the blade away. When a bandsaw blade breaks it can jump out under the table and into your body. I have a cousin with severe brain damage after this happened to him severing an artery in his leg and it taking too long for anyone to come to help.

Time to make a frame saw with the wasted blade. :)

You could cut it and reweld the joint but this would make the blade to small unless you have room for readjustment. If you don’t have a band saw blade welder you would be cheaper off getting a new one. This the only way I know to safely repair a kinked blade.

Don’t mess around with a kinked blade. There are some good uses for used BS blades.

I am thinking of turning my 14 tpi blade, that rusted, that I felt had become unsafe due to the oxidization, into a bow saw… its still sharp enough to cut flesh… so I imagine it will work for wood. I ended up breaking it, when I pulled it out of the trash can, since I was thinking of using it for one brief job… I nicked my hand pretty good…

You might think of doing that yourself(the bow saw part… not the cutting your hand part…)
