I picked up a big V twin industrial Atlas Copco unit at a clearing sale very cheap. Its about 120 scfm. Set up a pto drive off a tractor. Found a large pressure tank with a lid. Its no good for light sheet though. It will cut it in half if you hold it too close. Just use sand that has been left out in the sun for summer & sieved through some fly wire. 120 psi stops it from blocking.
