Start the taper behind the rear seat and keep the changes to a minimum. If you widen the fuselage at the front you will need another sheet of plywood, you will also have to change the wing center section width, redesign the upper wing attachment points and then the wing strut angle will be off so you will have to change the lower and upper fittings......also adds more weight. I know other people have suggested doing this in the past. I just don't know who and if it was done.

It is an alooy of iron, chromium and nickel. The variety I use is much stronger than mild steel, as used in the early Piets and slightly weaker than 4130, which is an alloy of iron, chromium and molybdenum. AISI 304 is very TIG weldable too. We use about 2000 tons of it per year for our manufacturing.

I'll have to weigh an assembly to see how much mine weigh. Bill C.

It is just to explain the material is readily available to me. Yes, we use about 7-10 tons per day. The hinges are laser cut from 2mm (0.08")=8B thick material. When ass embled, they show almost no sideplay. Personally, I did not like the idea of 3 eyebolts. I also made more stuff using ss and laser cutting (yes, we have our own CNC laser). They are quite different from 1932 fittings. My rudder pedals are different too. they are all pedals, no rudder bar, with Castamide bearings. Do you have any photos of your hinges?

From: Douwe Blumberg Sent from my iPhone ________________________________ Message 14 ____________________________________ Time: 06:28:34 PM PST US Subject: Pietenpol-List: Re: Question re posting progress From: "Bill Church" Semih, Attached is a photo of my hinge assembly. As you can see, the weight is 24 grams (or about 0.9 ounces), according to my cheap digital scale. Mine are made from 16ga (.058") AISI 304 stainless steel, and I polished them up using a buffing wheel and some polishing compound. I have also made a few other fittings from stainless steel, including my control horns. I used the same basic design from the 1932 plans (airfoil shape from light gauge sheet metal) but I had the blanks punched out using a CNC punch press (+/- .004" accuracy). Very happy with the results, with the added benefit of corrosion resistance offered by the stainless steel. Bill C.

I think I was inspired by your hinge design. The only thing is I overbuilt. I have a handicap of 144 grams (5 ounces). If I need weight saving on the tail in the future, I will certainly build new hinges. Did you weigh other stuff? if so, I would very much like to compare figures. My idea of control horns was different. I am posting the photo of the last elevator horn.
