27, 2005) at 08/26/2005 09:07:57 AMThanks Robert,No, I do not have any patterns or plans of the cowling yet.I just build it, I started off with some foam and shaped a nose bowl.This foam nose bowl became the male plug/mold for the fiberglass/ epoxybowlI did not make a traditional female mold.This nose bowl I then mounted on the Prop hub and rest is made fromAluminum .02- 2024Same for the Eye brows.I did not know how big to make them to get good cooling.So expected to have to remake them, either smaller or bigger.They seem however spot-on Temperature on full power climb is about 420 FAt 75 Mph cruise it is around 375. And that is in Texas heat of 100 F.They might be to big for winter.The Picture gives the cowling more credit than its due, close up there area few imperfections.But it is good enough for flight.I do intend to redo some of the Cowling, I want to make a aluminum nosebowl an redo some of the top parts.I might make some pattern drawings this winter.Hans "Robert B.

I am in the beginning stagesof building a GN-1 Aircamper, and I too want to use a William WynneCorvair Conversion. One of the only reasons I have considered not usingthe Corvair is because all the Pietenpols I have seen before with thisengine did not have cowlings that I thought were very attractive. Thenyou posted the picture of your plane. Once again what a piece of art!I immediatley focused on the way you cowled your aircraft. It appearsthat you have put eye brows on the plane. I love that look, but have onlyseen them on Pietenpols with Continentals or Lycomings. Did you design youown cowl and eye brows to fit the Covrvair Motor? If so do you havepatterns left over that you may be willing to sell to other builders. Letme know I would be interested.Robert B.
