You know, one of the reasons I read this forum is for this kind of stuff. You have no idea how many times I've avoided i-mode myself because some poster had done the same thing and written in about it.
I have some rebar to cut this weekend, and I considered this very thing. I thought about things like RPM, blade/disc runout, jig-building, etc. The one thing I probably wouldn't have considered is melting the saw. I don't think my warranty would have covered "melting."
My mitre saw and I both thank you for the tip!
