S Hardy - I'm Only 1" shy of height clearance,possibly 1/2" in some places. Now I might entertain the thought of useing a oval globe or maybe...just maybe... panning the ceiling in a samll area,but, if I were to start cutting a recess in the concrete to accommodate a pump...I'm almost sure I would see a divorce lawyer poping his head out from the floor.LOL. My wife is pretty understanding in regards to this hobby,but,I would be pushing the limits to "SANITY" with the use of a concrete saw and a jack hammer. Thanks for the suggestion...but I think I will choose to stay married.LOL
