I assume it is not wise to attach any of it to the engine because of movement, so do es the entire assembly cantilever off of the firewall area of the fuselage only? It seems strange to me that there is no support out by the propeller. Any help, tips, tricks or suggestions would be appreciated. =0A=0AThanks. =0A=0AIf God is your co-pilot...switch seats.=0AMichael Perez=0APietenpol H INT Videos=0AKaretaker Aero=0Awww.karetakeraero.com ________________________________ Message 2 _____________________________________ Time: 01:13:23 PM PST US Subject: Re: Pietenpol-List: Engine Cowling Help From: Ken Bickers I'm at the same stage as Mike, in terms of cowl fabrication, and welcome any suggestions.

I'm glad you took the time to access that information! My cowl came out nice, though I continue to modify it. One of my long term goals will be to reduce the 5,347 stainless screws, by at least half! With some 'noodling' I am, little by little, gathering a plan to use pins (like Mike Cuy, Greg Cardinal and a few others.) instead of some of the screws. I will also be able to employ some piano hinges that will eliminate a couple hundred more screws. What I am finding is that removing and replacing the cowl is a daunting task, and I'm sure it discourages me from looking into the engine compartment as often as I would like. Best wishes!

It takes about 30 seconds to pull the clips and have the top cowl off. I have the Cub cowling off the Grega and can take pictures if you need them but looking at a J-3 in person is a lot better.

You can see where the support tabs are located on the firewall, plus one in the center at the bottom of the firewa ll. The tabs along the top bow of the firewall are located where the cleco's are. Michael, you are right that the cowl needs to cantilever off the fire wall and not touch the engine or motor mount. Once you get it designed, bolt ed and riveted together, it's surprising how strong it is. Make sure you make good use of thin cardboard patterns before you start cutt ing metal. The cardboard I used was cardboard used to protect product on pal lets that I got for free from Tractor Supply Co. Rick Schreiber Valparaiso IN
