Subject: Pietenpol-List: metal fatigue minimized by using 0000 dead soft aluminumI have had very minimal cracking issues with my hand-made Cub style cooling eyebrows/bafflessince I used 0000 or dead soft .025" aluminum to make them. The dead soft resistsmetalfatigue very nicely and makes forming that reinforcement wire into the leadingedge an easyevent. ________________________________________________________________________________Date: Wed, 31 Mar 2010 12:34:02 -0500

Thanks Michael. I am going to cut another piece and I am trying to decide whetherto use the same .025- 2024T3 or switch to some soft aluminum I have on handthat is about .035. I have no intention of making a special order for more.andI don't think the thickness difference will amount to much more than a halfpound. I'm only talking bout around 2 1/2 sq. ft. here if I use the thin I thinkI'll forget the rolled up edge and just cut a little more clearance and usesome rubber edge trim over it.I need to get off high center and keep this projectmoving along while I have the time at home.and I don't need a complete rollaround wire-just an up turned lip would help stiffen the area and give extraclearance if the engine shifts enough.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
