My apartment has 8x10 beams running across the ceiling spaced about 64" apart. I realized recently that this would be a great place to install a 1" galvanized pipe with flanges at the end to be used for weight bearing purposes (pullups, gymnastic rings, hanging chair, etc) in one corner of our living room. In other words, there would be a 1" inch pipe spanning the 64" gap, with 4 fasteners at each end for the flanges.
1) Is there any reason this project wouldn't hold up to the activities I've described?
2) What fasteners should be used? Obviously not drywall screws, but would nails be better than wood screws given that there will predominantly be shear forces involved?
