Thank you very much ED you just made my mine up what i want to put in my basement I have plenty of Tractor supplys around me so finding then should not be an issue. beside i love tinkering with things I dont thing the paint will do to much damage, should be ok after it dries How much penetration are you getting, anything sticking out of the backside. just wondering how close i can set one to a concrete wall?? Thanks for putting together, i enjoyed it
