My memory is that at least one of the height measurements on the plans putsa kink in the rib. It's pretty obvious which one is off--I think it's a fewinches back from the leading edge.Gene Hubbard-----Original Message-----

This is probably not the measurement Gene mentions, but at the leading edgeon the rib drawing it shows 1-1/2" height. It's the first measurement.What's that for? Kent-----Original Message-----

I have all the plans from Donald, and he sent the full size rib drawing. Idon't have the F&G magazine. But I have heard mention of plans changingwith temp and humidity, so I want to draw them out. If I find myself to bea bad artist, then it will be time to use the drawing. I'll give it anothertry tonight. -----Original Message-----

Mike, Thanks for the attaboy - it was a long hard road, but I finally made it. They say the that the CFI is the toughest Oral/Practical in aviation, after mine, I believe it. It was 10+ hours spread over 2 days. I was drained. Funny thing about the CFI is once you get it, you don't feel any smarter than before. I was sorta hoping that a magic knowledge switch would go off, and I'd know everything! Oh well, I guess it's back to the books....As far as flight reviews, the chance to do one in your plane with you is all the incentive I need!! Let's go!!Thanks Mike, and Happy New Year everybody!Gary MeadowsSpring, TXSend and receive Hotmail on your mobile device: http://mobile.msn.com________________________________________________________________________________Date: Wed, 2 Jan 2002 11:41:10 -0800 (PST)

It's pretty obvious which one is off--I think it's afew> inches back from the leading edge.Working from the old Flying & Glider Manual reprint, I found enough problemswith the rib dimensions that I couldn't figure out what was supposed tohappenat all. Wound up calling a friend who had used both that and thelong-fuselageplanes to produce a very sweet plane. He solved the problem by giving mehisrib jig, which seemed the best of all possible ways out. Years later, theribs arestill in good shape--and waiting for me to start on the rest of the plane.Soon...after we get through moving to a new house with more space to work andbetterweather to do it in.Owen Davies________________________________________________________________________________Date: Wed, 02 Jan 2002 12:49:36 -0500

Kent,The 1-1/2 inch measurement is the height of the most forward point of theleading edge (after shaping). I'm sure thaat NACA had a real term for it,but it's the height of the first point of both the top and bottom wingsurface. The trailing edge is 60 inches from this station. Neadless tosay, the finished airfoil is vertical at this point. Also, since theleading edge is attached at an angle, the rough material will stick out abit from this point before you plane (or whatever) it off.Gene-----Original Message-----
