Well a 1 gal Graco accumulator tank pumped to 30 lbs for $110 did the trick. I appreciated waterguy's ingenuity but went with the industrial, adjustable, sure deal for a few more bucks.
Thanks everyone for the great advice. My wife will think I am a genius - at least for a while until I screw something else up.
