Very cool idea, and I like the development...
Much better than my aborted attempts to do stuff with a roundover and layers of 45 deg chamfer bit cut MDF... a total pain to accurately dimension layers correctly. And, only flat profile guides possible...
I agree that using some better grade of steel would be an improvement, if only at the cutting edge, but won't even mild steel (is it?) like the angle iron alloy temper a bit? Might be worth heating it up to red, then dunking it in a bucket.. to see if that extends your edge life on your current one... (edit.. read the last post a bit closer, ah well)
I'll ask a mech type at my work about current accurate cutting tech out there, plasma, laser, high pressure water, EDM, etc... Might be a way to go, (if cheap enough) to find shops where you could give them a profile CAD file and a saw blade or piece of good sheet steel, and they'd hand you back your finished cutting edge piece.
Another innovation that looks necessary, would be some kind of dust collection box or tent around the drill press... especially for MDF! 8O That's got to be a prodigious amount of powder being created, making the guide!
