A couple of days ago a piece of Owyhee jasper came loose in my 10" saw and bent the blade really bad. I took it off and hammered it out, and it is now working fine. Afterwards I thought that I should have taken a picture of the bent blade and the results of the hammering process. Well today I get another chance!! My 18" saw made a clunk this morning, and this is the result of what happens when the piece you are cutting fractures and then moves in the vise. I will hammer the blade and then see if it will work, pics to follow. PS- The 10" blade was thinner and therefore much more bent, I was actually surprised that it hammered out ok. It would have made a much more dramatic picture!! Tony

Did this happen in what they call "auto feed"?
It is not something I have to worry about while learning with this little Workforce ... is it?
As always ...

OK, Fixed and running again!! First step, take the blade off and set it on a couple of 2x6's or 2x8's. Set another piece of 2x6 on end over the section you want to push down, and give her a few good hard whacks Turn it over and repeat on the high spots, keep doing this until you have it straight again. Put your blade back in the saw and turn it slowly to check for alignment, you may need to repeat some of the above steps until it runs true again, (if you have it kind of dished just hit closer to the center on the high spot and it will true it back up again) Then tighten er back up and cue up your rock (making sure it will not move in the vise!) Back in business!! Have a great weekend!! Tony

Oh, at first your blade will hammer a little, as you have stretched part of the rim by hammering it back, that section of rim will eventually grind off and become round again as you cut.
Julie, It can happen with your saw, but it is much more likely to kick the rock out of your hands, than to ding your blade. Easiest to cut from behind so if it kicks it out it will not hit you. Most of all have fun with it, it is fun fun fun!

You're good not only in slabbing but also in fixing the problems. Glad to see the saw keeps cutting.

My question is do you know what caused the problem that bent the blade in the first place?

Thanks Adrian, Now if I could only become as artistic as you, I would be able to make something!
Ron, Yes, the piece I was cutting broke where the vise was tightened up on it and the stone rolled, causing it to bind up and ding the blade. The same thing happened both times. I suspect the vibration of the cutting causes it to break at a weak point. I try to get it blocked up so the vise will hold it better, but some where down the road you have to make a cut that is not optimal before you can get it blocked up
Tony.

So, you wanna try on an old blade of mine? I have a 14" that died on a chunk of Bruneau a few years back...

I would be happy to do it for you, but to try to save you the shipping costs, it is soooo easy, that just about anyone can do it. If you still don't want to tackle it, send it on over and I will whack away on it.

Good fix, thanks for posting this. Be careful what you wish for, huh? Jo

Great job of fixing that bent blade! I would not have thought it fixable, but there is a lot of diamond left so the well worth the try, and I am pleased to see that you were successful! Woody
