<font size=3>Here's an experiment someone could try before a pitch
raise:<br>
<br>
Test 1<br>
Tape a strip of paper to a rib adjacent to a beam.<br>
Extended the strip down beside the beam.<br>
Mark a reference point on the strip and the beam.<br>
<br>
Raise pitch, look for board flex as indicated by the reference
marks.<br>
Leave the strip attached to follow humidity fluctuations.<br>
<br>
Test 2<br>
<br>
Tape a thread along a strut and mark its position on the strut.<br>
Raise pitch and note any change. Leave thread attached for future
reference.<br>
<br>
<br>
Just a few thoughts.</font><br>
