John, It is 1/2" X 1/4". Also note in the F&G article the rib dimensioncorrection from 6" to 6 1/8" I believe it is, and the notation of thedirection of the last rib brace piece, as both are structurallysignificant. And do take Mike's advice and get all of Tony Bingelis'sbooks. The plans and the articles give you a lot of tasks to do and Tonyshows you several different ways to do each one, most of the time.Have FunWarren________________________________________________________________________________

The 1/2" X 1/4" is the correct size per the plans. This is overkill though.Many airplanes with higher gross weight use only 1/4" X 1/4", I know ofseveral airplanes that use 3/16" X 3/16". If you want a good performingairplane keep it light. If you look at airplanes made by B.H. Pietenpol,the dimensions of ALL wood parts are actually about 1/16" less than theplans. He measured to the center of the blade kerf, not the edge of theblade.I've been watching all the questions about the plans. I bought mine fromMr. Pietenpol back in the mid '70's. In the set I have, the dimensions forthe 3 piece wing vary from the one piece. It would be a good idea to verifyall dimensions prior to cutting any wood. A simple method to keep yourweight down if you plan aon a 3 piece wing is to make it 2 piece ratherthan 3. The additional fittings and ribs weigh about 6 lbs per side. If youbuild one wing with the center section and the other wing with only theouter panel, you save about 6 lbs. Another important modification is tobuild your outboard strut attach fittings in line with the strut. Theoriginal plans call out for the fitting to straddle the spar and attach tothe strut at an acute angle. This puts a bending moment on the fitting andspar. If you make the fitting and bolt holes in the spar in line with thestrut, it reduces this bending load. Another area to watch is the fuselagefittings. Some of the fittings will have interference with bolt heads andnuts if built as drawn. Made cardboard mockups to verify the position ofall hardware before you make the fittings.John Duprey wrote:> Hi Guys:>> I have both the EAA's reprint of the flying and glider plans & a set> from Don Pietenpol.

Hi Guys: I have both the EAA's reprint of the flying and glider plans & a setfrom Don Pietenpol. On the Large plans and the Flying & Glider drawingsit shows wing rib stock to be 1/2" X 1/4" but in the F&G text it says1/2" x 1/2" which is correct? Thanks! And thanks to Steve for runningthis forum to help guys like me build my airplane.John Duprey________________________________________________________________________________
