I have an old four foot diameter saw mill blade. They are readily available in the piney woods of east Texas where I live. I annealed the steel ground out a beautiful little drop point and when it came time to harden it I could not get it to harden even in water. Anybody ever had this problem?

Yes, not all sawbladesd are created equal.
When I get a sawblade to use for blades I send a piece out and get it spectographed so I know exactly what I have. It's worth it if you have the wherewithall to process that much steel and don't want to buy new stuff.

As birddog said. If you are using mystery metal and you have a large supply available it's well worth it to get the material specs. Once you have the specs in hand, now you will know how to proceed.
Yeah I am in Longview, where are you?

Round sawblades that have carbide teeth brazed on generally are made out of a lower carbon alloy that won't harden. About ten years ago, I went through the same thing you just described. It's pretty depressing, doing a lot of work basicly just for the practice. If you find any blades that don't have brazed on teeth, they'll usually harden up just fine. New steel sure is cheap , though, and you know exactly what you're working with.
