Pietenpol-List: Centre wing section & fuel tank
Original Posted By: "Gary Boothe"
Fellow builders and mentors, Happy HolidaysWhat thickness of plywood is being used on the sides of the ribs on the topcentre section and bottom, holding the fuel tank?Any advantages or cons between making an aluminum tank or fibreglass one?Excluding the talents of the fabricator.Would you hold more fuel or less with one over the other?Drain fittings and fill connections, are they problem free over time in afibreglass tank?Those of you, who make your control horns out of one piece instead of twowelded together, what thickness of 4130 are you using? Is it necessary to roll the edges, or the thickness takes all into account?Any suggestions on part # and supplier that are being used for bearings onthe bell crank and main control tubing?Does the use of bearings, instead of the fabricated ones from the Pietdrawing's, give you a smoother feel for the flight controls?I have read that stainless bolts are ill advised/prohibited. Unable so farto get AN flush head screws long enough, for bolt through, for the hinges onthe tail surfaces. We bought those great aluminum hinges in Broadhead. Whatare fellow builders using for this application?In the event of a mishap, I'm concerned of the area to locate a tie downpoint for seatbelts. Is there an engineering point of view, concerningheight, angle, distance, load factor?Don't want to have a cable back to the tail that might act as a stranglehold on the Pilot in an accident. Perhaps if the fuselage was to break upthat bad, the seat belt would be the lease of an issue. LOLWell, Thank You in advance for any advice!Happy New Years & Blue SkiesMarc DumayChatham,On________________________________________________________________________________

Marc,My center section is built (more or less) to plans, with 1/8" plywood on thebottom and sides of ribs. One of the few changes I made was to push the ribsoutboard as far as they would go, gaining room for a couple more gallons.I don't have experience with fiberglass, nor have I built the tank, yet, soI'll someone else chime in on that.I agree with you about the seat belts and shoulder harness. To me, the seatbelt needs to hold you in in rough air, and the occasional, mis-managed rollor loop. Both need to keep your head out of the instrument panel andsupported in case of a nose-over, etc. Keeping in mind, that, no matter whatsystem you devise, it's still, after all, a wooden structure.Added to my fuselage, just under the pilot's seat, are oak blocks, facedwith 1/8" plywood and epoxied to the sides and framing members. The seatbeltattach fits thru a slot in the sides of the seat and is thru-bolted with5/16" bolts. A similar set up attaches the pilot's harness at the twocorners of the tray. As you say, if the fuse breaks up that bad, I have more to worry about.After slotting for the Vi Kapler hinges, I epoxied the hinges in place andattached with stainless, flathead screws and fibered lock nuts. Yes, I usedstainless! Are they as strong as their AN counterparts? I doubt it, but towhat degree? If those things rip out, I'm probably in an inverted spin andheaded for eternal Pietenpol flying in the Here After!Gary BootheCool, Ca.PietenpolWW Corvair Conversion, mountedTail done, Fuselage on gear(16 ribs down.) _____
