Well, there goes another perfectly good fly-in I'm gonna miss. Actuallyit's probably one of the best fly-ins I'll miss this year because it'sall about Pietenpols!My younger brother has the nerve to get married on the same day as thefly-in.And to a girl that doesn't even like small planes! Can you believe it.I was gonna hall my parts and engine down so everyone could point andlaugh. And eat hotdogs and other hanger food. And now I've got to weara suit and eat orderves made of stuff worse than hotdogs.I hope you guys take pictures and post them! Have fun on the 11th!!!(How in the hell do you spell orderves? I could have built another ribin the time I tried to figure out how to spell that word. Isn't therean 'h' in there somewhere? Where is my third grade teacher at?)Everything is now measured in rib building time in my life. My wifewants me to put a new light kit on the ceiling fan in the kitchen.... 1.5 ribs.... New railing on stairs on porch.... 1 rib.... Hell, Iprobably could have built a whole wing for the time it took to ceramictile the kitchen!Greg YotzP.S. Robert Hensarling, I talked to Don Tevis today and he wanted meto ask you how it was going?-----Original Message-----

Greg,Since you're hot into the rib building phase maybe you can tell me if I'm doing it wrong - or have the wrong expectations.I'm getting springback when I take the ribs out of the jig. The undercamber tries to flatten out and drags the top of the airfoil with it.Are you steaming the rib bottom strip as well as the upper forward part?Did you over bend the undercamber and upper strip to compensate? If so, how much?What wood are you using?Thanx,DG________________________________________________________________________________

DG, I never got any springback on mine, and I only soak front 16" in boilingwater for 10 min. They seem to lift out of jig as solid as a rock. You areputting gussets on one side, before removing from jig? and not till fullydry.walt-----Original Message-----

Make sure you have the gussets on the front side and they are fully dryfirst.I only soak the first 18" or so of the top capstrip. The first rib I did, Igot in a hurry and didn'tglue the gussets on.(duh) Pulled it out and things moved everywhere. Thegussets are whereall the strength come from. They have to be glued well and fully dry beforeyou removethe rib from the jig. I guess this is really a prestressed assembly.I use spruce.GY-----Original Message-----
