Alex and Group,Today we weighed the wooden Pietenpol fuselage using an oldbathroom scale and it seems to be about 70 pounds complete with turtle deck, fairings, seats, instrument panels and firewall.Spruce and birch plywood was used (except for the seat bottomswhich were mahogany plywood). Ash crosspieces at the landinggear/ lift strut attachment locations are in place. This fuselage faith-fully follows the 1933 short fuselage plans and is varnished. Theworkmanship is good.One of these days I'll calculate the weight of a steel tube fuselageusing weight per foot figures for the different tubing sizes. Then I'll estimate the weight of seat supports and stuff like that to come up with a comparable figure for the steel fuselage.So figure on about 70 pounds for the wood in a typical Piet fuselageready for metal fittings, etc. and you will be reasonably close.Graham Hansen ( In Camrose, Alberta, Canada---where it is COLD today.) ________________________________________________________________________________
