You think I'm misconstruing you, Rick? I take offense to that! Them's fightin' words! You just wait 'til Blade! 
Nah, I'm glad I persisted in asking questions. I learned a few things. Thanks for your help.
Vaunripped - Sounds like a good plan. Taking Rick's data in mind, sounds like if you single quench, bring the temperature up a bit hotter. But I find that a lot of my students let it get too hot if I don't tell them to pull it out of the forge anyway, so that's perhaps a relative term. Check with the magnet to see when it stops sticking, which is surprisingly cool, then bring it up hotter than that.
Personally, when I edge quench, I plunge the blade deep into the oil to begin with, then rock the blade up to leave the edge only in the oil, then rock it back down slowly, then up and down until I pull out of the oil. It gets some hardness into the spine, but not as much as the edge. Then draw temper the same as you would for a fully hardened blade.
Don't worry about heat treatment being touchy. We all have our own methods and as long as the theory is sound and most importantly *the results are good*, it's ok.
