I want to order enough wood to get me through ribs and the tail section. I have a material list from Robert McKinley (revised by Mark Chouinard) from a few years ago. When I add up the ribs (I want enough to build 30 ribs to allow for damage, etc), I get a total of 95 pieces at 5 ft (I plan on the one piece wing, which I'll build in a hanger). The list has 110 pieces. I'm including all the sticks that support the rib. Am I off (I plan on 60 pieces of 5' for capstrips, 35 pieces of 5' for the internal stickstotal 475')? I tried to measure the upper capstrip to factor in the shape/curve, but it still seems a 5 foot length will work. Will 5' be long enough? I already have a 8X4 piece of 3 ply mahogany, 1/16". I'll use it for rib gussets. Regarding the tail section, the materials list mentions 1X1 pieces, but I don't see 1X1 on the plans. Where are they? Anything else I should consider?

While it looks like the full size drawing, I can't get the two to line up. Right off the bat, the drawing is 60.125 (when adding all the lengths); a tad longer than the 60" published chord. Maybe the depicted measurements are off? If I use the full size drawing (assuming it's correct), it seems I'll have to move each spar a slight bit to achieve the depicted spacing. Having said that, I heard once that Piper allowed up to a 1/4" of slop, so maybe I shouldn't worry about it. How much deviation is acceptable? 1/4" OK? I'm thinking about which way to go: -use the full size drawing as is. -use the full size drawing and move spars 1/16" each to achieve proper space. -use the layout I drew based on the dimensions on the drawing. On the subject of measurements, I've seen that all rulers are off a bit (I measured all my rulers). I try to use the same ruler consistently.

Everything I have is from Wicks or Aircraft Spruce. I have a large supply of T-88. I hate asking questions, but sometimes I can't help myself. That 1X1 got by me. Thanks again. -------- John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=426862#426862 ________________________________ Message 15 ____________________________________ Time: 07:29:44 PM PST US From: "Clif Dawson" Subject: Re: Pietenpol-List: No Content I haven't had my own for some time.

After getting out my old textbooks tonight I discovered I was right. Determining the lift coefficient required at cruise from aircraft operating weight, speed and air density is correct but to determine the incidence angle that should be set for cruising speeds the aspect ratio of the wing and the angle of attack at which zero lift is created must also be factored in. Doing so I found that for the operating weight of 1150 lbs. that we have been using and a speed of 75 mph on a Standard Day both the Riblett 30-612 and 30-613.5 should have an incidence angle set at about 3 degrees positive. That works out to the front cabane being longer than the rear. For those of you that have built your plane with equal length cabanes this length would be appropriate for a cruising speed coefficient of lift of about .46. One would see that cruise speed lift coefficient at lighter operating weights, cooler than Standard Day temperatures, lower altitudes, higher speeds and combinations of these conditions. For those with front cabanes one inch longer than the rear the resulting incidence would be appropriate for conditions that produce a cruising speed lift coefficient of about .62. This would be appropriate for heavier operating weights, slower speeds, hotter days, higher altitudes, less dense air and combinations of these variables. I apologize for any confusion I may have created with my earlier posts.
