I'm not sure which direction I'll go there. I could make a similar blade, but make it about .5" longer. Or I could do some single tooth type of setup. I'll probably leave that design up in the air until I get the thing driving, covers made for everything, etc. That way I'll know how much weight I have to play with. With the current setup, I'm about 1 oz under weight.
I no longer have a programmable heat treating oven, so I'll have to farm the hardening out. I'm hoping to machine the blade myself, which would force me to keep the design pretty simple.
