The good news is that we no longer need to worry about getting it sharpened.

The bad news is that sharpening wouldn't do it any good.

I hope no one was injured in the destruction of that blade.

Nope. The blade broke as it approached the end of a miter cut on a piece of 2" x 1/4" steel angle. All the pieces dropped on the saw table.

Any suggestions on what to do with the pieces? I'm sure it's pretty good hardened steel, so it should be useful for something.

Make good cutoff blades if you could get them cut without annealing the metal..

I think I'd be sending it back to Doringer and ASK THEM what to do with it.

I used their saw and blades for many years, never had that happen!

Man, that scares the bajeebus out of me regardless if it happened at near stall speed. I just never hope to see a circular blade of any kind looking like that in my shop! :eek:

I work with rotory transfer machines and use those blades, that is prity common. Ofcorse in my case thay are inside a machine with the lid locked. Thay only run at about 200 rpm.

The Doringer web site lists 54 rpm as the blade speed. I wouldn't think it would likely do too much damage shattering at that speed.

Blades break. Buy a new one.

My dad made some knives out of the old one. Darn sharp.

My first thought was that if you are going to use parts of it to make a tool or whatever, you should fully anneal it first. Make the part, then re-harden it.

Someone might offer a more educated opinion, but I'm thinking that there could be stress peaks in the material that you could get rid of by annealing and re-hardening.

A little J B weld and it will be as good as new. :)

Some "billet" silver solder and your barbecue you should make it almost as good as new.

On a serious note, I have cut "saw plate" with my vertical metal cutting bandsaw. I used a 3/8 inch 10/18 pitch blade and it worked fine. Drilling is another thing altogether -- It is drill all or none, if you pause it will work harden instantly.
