Just replaced the bandsaw blade with a 1/2" x 4TPI blade last week and had about 4 hours on it. Wouldn't ya know it, I was pushing a small piece thru and it bounced because it was improperly supported. (For safety I should have had a flat waste piece supporting it underneath). 🙁

Anyhow I kinked the new blade. It's a minor kink but irritating. Any tips on unkinking it? Or should I just put up with it? Mostly the bandsaw is used to do cleanup on roughouts when I get too lazy with the chainsaw.
 
blake kink

Jeff, You can try hammering out the kink by putting it on a flat steel surface and, laying a small piece of steel on top of the kink and hitting that piece with a hammer. Directly striking the blade will probably not solve the problem but could add a bunch of small kinks or break off some teeth. My attempt to do this was marginally successful. Either way I doubt the blade will ever be the same. Good luck. Phil
 
kinky

I read somewhere that a kink isn't always a bad thing. It widens the kerf and reduces binding. It does make the surface of the cut rougher though. For turning blanks it doesn't matter if the cuts surface is smooth since it will get turned away.
 
Hi Jeff

I bend blades on a regular basis, and it always seems to be when they are new. I grab the blade on either side of the bend with a pair of pliers (that's two pair of pliers) and bend it back to straight, or at least as close as I can. The blade will thump along, but you will get your money's worth out of it. I wouldn't try resawing any veneer with it though! 😱

I've done it a few times, and I HATE it when that happens :mad:

The kink(s) usually ends up at a diagonal, making it more difficult to straighten.

You have to know exactly where the kink is, otherwise you're making a new bend. It helps to mark the blade with a sharp pencil after looking at the area closely from many angles. Then use two pliers to straighten it.
 
Thanks for the tips folks. I used 2 techniques.

1) I used the 2 sets of pliers trick to do some straightening. then...
2) I hammered the affected spot between 2 solid pieces of wood (on the ground).

The kink is a lot less noticeable now. Thanks again.

Jeff :cool2:
