Subject: Pietenpol-List: Wood disc, nose cowl Hi all,Well, as you may remember a few days ago, I asked the question, whether or not the "pine disc" as referred to by the 1934 Hoopman plans, stayed with theairplane, or was discarded after formation of all the cowling pieces (this isfor the Ford A motor). I got varied responses, but I would like to share two of those with you that I received from two well-respected members of the Pietenpol-builders fraternity.

You need to seal the threads on the two top bolts or you will have a big oil leak. Taper the outside of Discto line up with firewall.KenForrest Lovley wrote:In the original airplanes, Bernard used a wooden disc on the front of the cowling. It was used to make the transition from the side cowls to the nose cowl used on the Ford. The disc was fit loosely on the front of the engine, not bolted tight. The sheet metal was NAILED to the wooden disc. This was common practice in those days. Waco nailed their sheet metal on the early airplanes also. Those airplanes were not meant to last long enough to have totake it apart. It would be easy enough to make an aluminum bulkhead to join thealuminum for the Ford cowl when building one today. However, the wood worked just fine for the job it was asked to do.Forrest LovleySubmitted by:Dan HelsperPoplar Grove, IL.**************Ideas to please picky eaters. Watch video on AOL Living.
