And yes, I'm
interested in a heat treat oven as well, especially now that I have
a
surface grinder.

I've sharpened woodworking blades on a surface grinder. They burn very
easily unless I take off only a few ten-thousandths per pass. The mag
chuck won't grip rough work until it has been milled flat and
straight, and it's difficult to hold and support the blade securely
enough over its full length at an angle.

When I had access to a quality surface grinder, I used it to sharpen
the D2 blades from my 6" jointer. It worked great but I still had to
hone them by hand afterwards.

I've also tried it on carbon-steel plane irons. It's very difficult to
keep them from burning because they're probably tempered at around 350
deg. F at the factory.
