Dave, When you laminated the spars, did they stack vertically || or horizontally = ? I wonder if it makes a difference. Same for center vs outboard spars?

Have to be sure it meets specs in grain run-nout, no knots, etc. For the longerons I planed it to 5/8" thickness (left the height at 3/4", dampened the longerons and bent gradually over several days in assembling/shaping the fuselog: no cracks/splits. Laminated the spars ;do not want to cut spars from thicker pieces due to possible hidden pitch pockets. About 15% heavier and stronger than sitka spruce, a little over build/safety facter. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
