Subject: Pietenpol-List: Ash engine supportI am building a long fuselage Piet with a Corvair and have a question about the the 1 1/4" x 1 1/2" horizontal ash engine support which attaches to the front fuselage vertical braces and firewall. Can see the need for it when installing a Ford engine but seems a bit hefty for a Corvair installation. Hasanyone used a lighter piece for this like 1" x 3/4" spruce?ThanksRick H________________________________________________________________________________

Rick,I'm building the Continental version, with the motor mount per BHP'ssupplemental plans. I decided to use a 1/4" birch ply forward bulkhead toback up the firewall and provide a support for the upper cowling. With allof this material on the front, and no particular stresses (the engine mountgoes directly to the longerons), I used two 3/4" (I think) square ash crosspieces gusseted to the forward uprights and glued to the forward bulkhead.The engine mount brackets preclude structural pieces at the top andbottom--I think I put the ash cross pieces at BHP's original locations wherethe radiator floor would have been and about 6" off the cockpit floor. Iused a spruce filler strip across the cockpit floor to have something toglue to, but it doesn't provide any real structure because the ends can'tmeet the longerons.Of course, this hasn't flown yet, so it's not "tested", but it seems to makea pretty good package, and provides a good front support for the gas tank.Let us know how your project goes.Gene-----Original Message-----

I put mine in anyway. There is a lot of weight hanging off the front. Anyhelp in my view is good.CheersPeter.Wonthaggi Australiahttp://www.cpc-world.com -----Original Message-----
