On the advice of Mike Cuy in his recent post, I ordered and read a set of booksby Tony Bingelis (at least those sections/chapters which pertain to wooden construction).In fact, I've read through them many times.On page 73, in the section discussing wing rib construction techniques, the authormentions a fellow named Les Long who used dual cap strips of 1/4" x 1/4" withthe uprights and diagonals sandwiched between them. A dab of glue and a nailat each joint finished it off. Excess length of the support members were trimmedoff and it was done. No gussets were needed.The wing rib cord was 54" and it weighed 3.5oz. It is reported that it took tenminutes to produce a rib.There is much that is attractive about this method, but I don't know how much aPeit rib weighs when built to plans. Can someone help me with those numbers?I haven't ruled out typical truss construction, but I'm looking at all options.--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 29 Jun 2015 09:35:07 -0500Subject: Pietenpol-List: Modern old engine idea

Andy-- I'm very pleased that you invested in the Tony Bingelis books---and, mostimportantly that you have dug in an started reading them!You would be surprised at how many questions you can have Tony answer sitting rightat your kitchen table with a cup of coffee. (coffee not required) Even after having had my plane flying for nearly 17 years I just broke open Tony'sbook on engines to find out how tight to torque my motor mount boltsfor my A-65 Continental. No guessing when you have those books. Mike C.Ohio________________________________________________________________________________Subject: Pietenpol-List: Re: Modern old engine idea

Finding a comparable, yet newer, engine may prove to be difficult, as current enginesare designed for rpm, and not torque.The bore / stroke relationship of an engine defines the torque and rpm characteristics.In the case of the Model A, the bore is a nominal 3 7/8, and the strokeis a nominal 4 1/4, both measured in inches. Generally, the greater the stroke,the greater the torque production.We'd be hard pressed to find a Spark Ignition (SI) - gas - engine with similardimensions, but in the case of Compression Ignition (CI) - diesel - I'm reasonablysure we can find something in that range. The weight of a diesel - otherthan one of the modern ones coming out of europe - will be very heavy, however.The european diesels have been designed for rpm's, however, and their torque, whilehigher than SI engines, may not be sufficient for a prop.Have fun looking; I'm going with either a Corvair or a Continental...--------Tom KreinerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 29 Jun 2015 12:00:49 -0500Subject: Re: Pietenpol-List: Re: Modern old engine idea

I looked into the AMC 4.0L straight six just before finding my Continental. Thesewere installed in the Jeep Cherokee and are known for torque.I think HP is 70ish. Not sure about weight.--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Modern old engine idea
