Pietenpol-List: Another rib question
Original Posted By: "Mark M"
There was a discussion about cutting your own cap strips a little while ago andI am a little confused. I have read the circular on selecting wood and and nowtotally lost. My vocabulary is limited to whatyamacallits and thingamajigs.Reason being,I lucked in to about 20 BF of spruce for $10.00 and was going toget started while waiting for my order to arrive. After I cut my capstripswhich way should the grain be running. Please check the drawing and let me know.ThanksMarkRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/file ... ___Subject: Pietenpol-List: Another rib question

I am plotting out the 612 rib and while looking at various photos of previous ribsmade i see that some have vertical supports along the spars and some do not.The Pietenpol original wing plan does not have them, with the attachment pointbeing nails along the top and bottom of the spar. Does having them makeinstallation easier later on? I would like to not have the extra pound or twoof wood if they are not necessary. Just trying to see the logic in the variousmethods.ThanksMarkRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sat, 23 Apr 2011 15:05:05 -0400

I'll bet it does. I'm not looking for a super slick wet look. I got semi-gloss.if it will just lay down smooth I'll be happy. I have already got it in Stittsthrough Poly-spray and flying it some. always did plan to do a finish coat onthe wings and tail.the fuse is Red now. but will do a cream-white flying surfaces.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Another rib question

Mark,I am a new guy, like you , and am just getting started on my ribs. I have chosenthe Riblett 613.5 airfoil. My apologies to all of the traditionalists, but Ithink that Lowell Frank and others have done a good job of convincing me to gowith a Riblett airfoil. The original wing ribs did not have the brace behindthe main spar and the additional vertical brace in front of the rear spar, butit seems that a lot of people have introduced them to the design as an improvement.Once you add the bracing/cables, it makes for a good design addition.I have added it, and you might consider doing so as well.--------Semper Fi,TerryRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sun, 24 Apr 2011 01:40:18 +0000 (UTC)

Mark,The thingie should align with the whatzit. :)Seriously though, for the wing ribs, the grain orientation isn't critical. Either"A" or "B" should be fine. More important than grain orientation is the grainrunout. Make sure the grain slope is no more than 1:15 (preferably even less)or you may end up with broken ribs.The grain orientation in "B" should be slightly easier to curve for the top capstrip.That's how I did mine.Now, if you're talking about spars, "B" is the only acceptable grain orientation.Start cutting.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Another rib question

Regarding the Pietenpol rib design, the original plans do not show the verticaluprights adjacent to the spars, but the full-size template (as provided by thePietenpol family) DOES have them. I believe that BHP added them to the designlater, to make the wings easier to assemble. Some builders opt to put uprightson either side of each spar (4 uprights), but this can make assembly more difficult,since the spar is "trapped" between the two sticks.Logic would indicate that adding a single upright at each spar is a good idea.The extra Spruce will account for approximately 3/4 of a pound added to the totalweight of the airplane.To the best of my knowledge, there is only one Air Camper currently flying witha Riblett airfoil, but it sure sounds as though there are a lot of ribs beingbuilt. It will be interesting to see how many get airborne in the coming years.Perhaps then we will be able to better determine how this alternate airfoilcompares with the original Pietenpol airfoil.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________
