I've had an off shore blast cabinet for a number of years now. Never cared for it, having used professional versions. I upgraded the pickup and gun, then installed a flood light. It was better, but I almost gave it away a couple times because it took up more room in my garage than it was worth.
Found these two videos on YouTube and the cabinet is now in my basement shop and working great. The guy in the second video is incredibly boring... but at about 10 minutes, he outlines how to drop the floor for more room.
