Screwed up my 12" DeWalt miter saw: Fix or replace

[Banjorear]

I did something stupid with my brand new DeWalt 12" miter saw. I was trying to cut a steeper angle in a small piece of wood. Well, let's just saw it didn't go well. The piece kicked back and actually bent some teeth at the kerf cut out and they got caught on part of the metal guard/dust shoot.

Now it cuts pretty good for framing work, but I can see and hear the shaft is bent. Is it worth getting a new armature for this saw or just replace it?

I didn't take it apart yet, but I'm assuming the blade attaches directly to the end of the armature. I didn't look up the part price yet, so I may be putting the cart in front of the horse on this post/question.

I'm so pissed that I was stupid enough to do this. I knew better but was in a rush.

Call DeWalt. If the saw is new, they may cover it under warranty.

I thought about that. I'm reluctant since I did it. The piece was unsupported and, really, too small to be cut it like I did.

I don't want to abuse a warranty for my stupidity.

Universal motors run too fast, so it should have a gearbox at the end of the motor to reduce its speed most likely you bent the Arbor and not the armature.

Thanks. I'll try to pull up a parts diagram. I hope that's all it is. Should be cheaper than replacing the saw.

Did you try the saw with a different blade? It's more likely that the blade warped than the arbor bent.

And 12" DeWalt miter saws have a belt between the motor and the arbor so that the motor doesn't get in the way of the cut.

I'll second the bent blade. It is much more likely than a bent shaft.

The blade was bent and usable. It bent so much that a tooth caught onto a part of the saw. That's what stopped it dead in it's tracks. I think all the energy transferred to the arbor shaft. It is certainly tweaked for I did a run out test.
