I used 6 Kuhn disc mower blades to make a 5 gallon mixer. These made a good mixer because the blades have a 5/8" diameter hole, about 3" long, sharpened on both sides, and already slightly beveled. The mixer was made from a 1/2" all thread rod, nuts, and bushings so the blades would fit snuggly. The drill to power the mixer only turns at 500 rpm, but it still makes fairly good batches of PC. The blades were sharpened on a fine stone grinder so it is important not to be careless when using in a 5 gal bucket because these blades will slice and dice.
A picture of the blades is posted in JD Neutron photos:

I was thinking of making a 55 gallon mixer the would look like a big blender by using bottom-mounted spindle from a riding mower deck that already has a pulley, bearings and support. This could be driven from the bottom by either a gas or electric motor. A four bladed rotor with swinging disc mower blades spinning at 1500 rpm should shred and mix.
