(I tried a search, but no help). I want to order enough wood to get me throughribs and the tail section. I have a material list from Robert McKinley (revisedby 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'llbuild in a hanger). The list has 110 pieces. I'm including all the sticks thatsupport the rib. Am I off (I plan on 60 pieces of 5' for capstrips, 35 piecesof 5' for the internal stickstotal 475')?I tried to measure the upper capstrip to factor in the shape/curve, but it stillseems 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'tsee 1X1 on the plans. Where are they?Anything else I should consider?Thank you.--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Corvair College

I've had two Corvair's in my garage for a few years. I'm now about to begin disassembly.I'd like to attend the college, but I won't have my work schedule untilAugust 18. Here's a few photos of my engines. One is from a Corvair Club member(he had several engines in specially built sheds), and I'm going to startwith that one. Here's my photo page (click on photos for larger images and sizeoptions are on the very bottom): http://imageevent.com/hatz/piet/corvair--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: ordering wood

I attempted to draw the rib based on the measurements shown on the drawing. Whileit looks like the full size drawing, I can't get the two to line up. Rightoff the bat, the drawing is 60.125 (when adding all the lengths); a tad longerthan 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 moveeach 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 worryabout 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 measuredall my rulers). I try to use the same ruler consistently.Thank you.--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: ordering wood

Thank you Bill; good point to mention there about plywood. Everything I have isfrom 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.--------JohnRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
