Looking at Santiago's beautiful Wing pictures-and seeing the Aileron view makesme wonder how much down aileron travel there is with the originals-has anyonegot the measurements on how much travel they have at the trailing edge from neutralto full up or down when rigged? Too wet to fly here in the Texas panhandlethis morning,but I can build.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 31 Mar 2007 09:20:58 -0400

Clif,The Grega modification cad drawings don't call for routing (they specifyaircraft spruce). Now I wish I had routed or looked into a built upspar -- at least my spars are laminated and strong.Tom-----Original Message-----

Subject: Re: Pietenpol-List: Wing weightHey Rick,Don't assume a negative attitude on fir. There is fir and then there is fir. Look for some cheap fir and you can sure find. Search around and find a reputable lumber business. Specify what you are looking for and give them a chance to provide. Then and only then fret about the cost. 41CC has fir spars,3/4 with areas routed which I would NEVER do again. My finished uncovered wings weighed in about 48 pounds each and around 60 totally finished. Her are the lumber specs I asked for: 16 ft length, 2X6 rough, Douglas fir vertical grain, kiln dried w/ straight grains at least 12 to an inch. My lumberman put me on hold for a couple of days while he searched his pile and cameback with the question, " would 18 to 24 grains suit you?". You too can find a source as well but don't accept that what is pushed by the price. Maybe youare not as old and ugly as Corky but he has learned that you ain't gonna get anything worth a d--- without paying for it. "Excuse me E"Found the fir to be only a slight few ounces heavier than the spruce I milled for 311CC. IF I were to build another which is totally out of reason I would go with good, light Douglas Fir for the entire Piet.Sorry to have butted in on your conversationCorkyRetired Piet builder************************************** See what's free at http://www.aol.com.________________________________________________________________________________Date: Sat, 31 Mar 2007 12:22:38 -0400
