---------------------- multipart/alternative attachment Here's an experiment someone could try before a pitch raise: Test 1 Tape a strip of paper to a rib adjacent to a beam. Extended the strip down beside the beam. Mark a reference point on the strip and the beam. Raise pitch, look for board flex as indicated by the reference marks. Leave the strip attached to follow humidity fluctuations. Test 2 Tape a thread along a strut and mark its position on the strut. Raise pitch and note any change. Leave thread attached for future reference. Just a few thoughts.
