It's not what you think - this is not a shear steel question...........

I was given a real old "cross-cut" saw ( I think that's what they call the big two man saws).

I plan on cutting some blanks from the steel. If I don't ruin the temper in cutting or grinding can I just buff and put handles on, and have a finished knife? Or should I anneal the metal, cut, and heat treat?
D'ya think this is L6?

Thanks,

As far as I know it may be plain carbon 10XX (xx = 70 to 95) or L6. If it is an old one then it may be possibly heat treated and tempered not arc hardened like some of the new ones. If you go slow you shold do fine but personally I would prefer to anneal somewhat then try to shape and then HT. That way I would have some control over the hardness I want. But you have to do some HT experiments before.

It's *probably* some form of L-6 in which case it probably does not need hardening or heat treat, you'll find out when you try to work the stuff.

I suggest getting a carbide bit, you'll need one.
 
I'll do one the easy way and one I'll anneal profile, grind and heat treat - then do some cutting tests on the both of em. Any other thoughts?

Be sure to normalize the steel after grinding, else warping-breakage may occur during HT.

L-6 appears to look slightly different than 10xx steel when polished ...sort of a glossy nickel sheen to it.

Then again, maybe I'm imagining things :)
 
Jiminy, only metallurgists can tell a steel just by looking at it !!....The term 'crosscut ' refers to the tooth shape ,meant to cut across the grain. As opposed to rip saw designed to cut with the grain. The big crosscuts come in both one man and two man versions.
 
How thick is it?
You can cut hardened saw blade with a cold chisel and hammer.


Old man up in Oregon used to make blades that way out osf saw mill blades.

Said he was real happy when they switched to the Swedish steel (Hn20) as it was easier to cut.
 
I have 3 or 4 old cross cut saw blades. Problem is, they are very thin for a single blade IMHO. I'd think that a person would have to weld up several strips of it to get any mass. Or maybe weld it up with a 10xx series steel.
