Lacking a metal bandsaw, torch or heller hack saw I was wondering if the Sawzall "torch" blade could do the job and survive more than one cut? 3/4" thick X 1 1/2" wide.
 
I've never heard the "torch" blade. My experience with cutting steel with a sawzall's was always a last resort. 3/4" X 1 1/2" O-1 will be quite a challenge.
 
I used a hacksaw to cut 1.25" by 7" through some O1. It took time, 4 by 15 minute sessions with a cobalt blade. Saved grinding!
 
Fiber metal cutting blade in a skil saw works wonders on cutting steel. Cost ya about $7 from Lowes or w/e y'all have in Boise.
 
I use a cutoff blade in a right angle grinder to cut all my steel to rough size and to remove big chunks. Then I use a grinding wheel in the right angle grinder to clean up and final profile on the 2x72" grinder.

Why don't you hot cut it. Use a hot cut hardy on your anvil and just hammer till your about 3/4" of the way through then turn it around and cut from the other side. be careful to not get the face of your hammer into the hardy tool. If you don't have a forge or an anvil you can use a chisel and oxy/acetyline torch. There is a benefit to hot cutting over using even a hacksaw. You don't loose any material.
 
Kvolle,

The reason that I can't use my hardy is that it fits a 1" hole and my anvil is 3/4". Now the obvious thing is to cut it down to 3/4" right? NO No... It's a nicely forged hardy that is waiting for my larger anvil that I will someday find. :)

Stubborn beats practical even at my age.

I think I'll throw one of those cut off blades from Lowes on and that should do.

Gotcha! I have some odd ball hardys that fit my father anvil but not mine. They were also hand made to fit his odd ball holes. they work great in my heavy duty bench vise. Which is how I use them. I know most would say it would be hard on the vise but it's been working for years now and I don't use it for this purpose that much. Just something to think about. Good luck.
 
The sawzall should work fine. Having a friend squirt some cutting oil in the cut avery 30 seconds will help, too. A VS sawzall is best for steel.
