I was wondering if anyone has experience building a functional indoor cross, or maybe came across plans for a working cross? *It needs to be constructed inexpensively... perhaps lumber? Metal piping? *It needs to be able to stand indoors... we don't have luxury of an outdoors crucifixion. *Can't drill holes in his apartment walls or ceilings. *Minimal tools available... probably just a power drill and basic household tools. Any help and suggestions making this work?
