Hello,

Apologies if this query should go elsewhere.

Anyway, I was using my bandsaw at the weeekend, to saw a log. Either a knot or imperfection, or a momentary loosening of my grip caused the wood to kink the blade.

I've swapped it for a new one, and I can see where the kink is. My question is - would you all just chuck it away, or can they be re-straightened? Naturally, I don't want to use it if it'll have been weakened, but I don't want to chuck out an almost brand-new Axminster blade if it's salvageable.

At any rate, it's taught me to leave ripping stuff like that to people who know what they're doing!
 
Hi,

Did the same thing my self this weekend and sheared the boss from a lathe face plate.

Hi,

You should be alright to bend it back again, it's not advisable to bend and straighten them if you can avoid it but once it's done if the thing is still in a loop you may as well carry on using it at low speeds and without exceeding the recommended tension.

For resawing logs, make an L shaped carriage from scrap (two planks screwed together) lay the log into the carriage then screw through the vertical component to the log. You can then treat it like resawing a big square block with gaps in rather than a round lumpy thing that won't sit flat on the table.
 
Or use a V block.

I have knackered 2 blades recently, it doesn't take much, and in my experience, the chances of you ever getting a decent cut from a kinked and straightened blade is about 0.

My last one had a similar snag to yours but with no visible kink and that would not cut in a straight line, always drifted one way, no matter what I did with it.
 
Think I'd bin the blade too... I might keep a few bits of it to make a heavy-duty file-cum-rasp though...

If you make little boxes, a bandsaw enables you to get nice 1/4sawn stock and sometimes 'Disco', it pays to cleave a log before you bandsaw it! :wink:

All this from logs that would otherwise be burned or left to rot in a copse somewhere. (Not that I begrudge the wildlife a home.)
