Milo,
What advantages does using soda have over using glass bead or other media for doing carbs and similar items? 
what kind of finish does it leave on aluminum?
I mostly use glass bead for delicate parts and turn the pressure down.

I blast in a cabinet. Usually use a small hand held blaster (like a 
paint gun, only for media, has a ceramic nozzle).
If I'm blasting a large item such as a small single cyl. lawnmower 
engine I will run my cabinet media suction line out the bottom of the 
cabinet and directly into the 50 lb
bag of of soda. Then I just use my cabinet blast nozzle. I don't try to 
reclaim any of the soda.
My cabinet is a Cyclone 4040
