After completing my 1st rib, I compared it to the rib drawing that came with the supplimental plans from Don Pietenpol, and I have pretty much decided to either redraw my rib (& rebuild the jig) or go by the drawing sent to me from Don. Mainly because they didnt match up. I know that the direction of on of the braces is reverse in the plans (the rear one) but other things didnt match up either, and I was very careful when drawing mine out. (mine was about 1/2" shorter at the tallest point, and the angle of the braces was off by about 10 degrees in places).Are the ribs, when laid on top of Mr. pietenpol's full-size drawing, supposed to match exactly, with the excaption of the rear brace? I have heard that there is an error or two on the drawing, but couldnt see what it was. I want to make sure everything is perfect before moving on to another rib. That 1st one is going to live on my shop wall as a decoration.Also, I got two sheets of 1/16" plywood from a company in Vermont. I'd say about 15% of it contains "discoloration streaks" of a light to dark brown color, ranging from 1/4 to 4 inches long, and about the width of a pencil to that of a thick marker. For the gussets for my 1st rib I worked around them, using only the pure, clean wood, but should they even be there at all? Should I be looking for wood that is completely free of marks like that before starting? I know of one other Piet builder that uses this same wood from the same company, and he has not mentioned it, so maybe it's normal.Thanks for any advice!Richardp.s. The Pietenpol I am making for MS Flight Simulator is about 65% complete! -------------------------------------------------Homepage: http://207.140.1.221/w3builderPietenpols: http://207.140.1.221/w3builder/piet____ ... __________
