I would like to use a soda blaster on wood. What would be the correct psi range?

I like to buy and refinish old wood objects and I am convinced that a soda blaster will suit my needs perfectly. However I still have to buy the equipment and before I get an air compressor I'd like to know if there is a preferred capacity and maximum PSI that I should look for. This would mainly be for stripping the finish off of various hardwoods.
