I was noticing that the ribs on the tail surfaces behind the spars arepretty flexible when you push them. I was thinking of putting some 3/8"square spruce spacers in to stiffen them up a bit and make them less easy todamage from hanger rash or people that don't know any better leaning onthem. Shouldn't add more than a couple of ounces to the weight. Anythoughts?Brian KrautEngineering Alternatives, Inc.www.engalt.com________________________________________________________________________________

The places where you bolt on the fittings on the tail surfaces for the bracewires, attachment brackets, etc. are recessed in from the covering about3/16" because the rib material goes over those surfaces.My first thought would be that you would put plywood on the surfaces thatthe fittings attach to so that they are full height and the fittings wouldgo over the covering. On the uncovered tail surfaces I have they arealready varnished and there are slight indentions in the wood where thefittings were obviously bolted on previously making me think that thebuilder had intended on having the fittings under the covering with the tabssticking out of slots cut in the covering and I guess the bolt heads coveredover giving you an ugly bump. Is this really how other people do it orshould there be plywood building up those surfaces, not to mentionreinforcing the areas.Sorry for all the newby questions. If someone could point me to a goodbuilders site with lots of pictures I could probably answer most of myquestions myself.Brian KrautEngineering Alternatives, Inc.www.engalt.com________________________________________________________________________________Subject: RE: Pietenpol-List: tail surface ribsDate: Mon, 10 Sep 2007 16:55:42 -0400
