Subject: RE: Pietenpol-List: Firewall FabricationJohn,I used thin (probably around .018" dead soft stainless steel from Dillsburg Aeroplane Works for my firewall and bent the flangeover on all sides using Tony Bingelis' easy method around the top curvature. I only have three small screws holding my stainlesssheet to my 1/8" plywood firewall-you really don't need a whole lot more because the motor mount ears and bolts do a nicejob of keeping it tight in addition to any cowling you screw to it. I did put a thin (maybe 1/8" thick or less) Fiberfrax ceramic blanketlayer between my 1/8" plywood firewall and the dead soft stainless firewall and just used a few dabs of contact cement on thatpiece to keep it in place while I installed the sheet stainless. I preferred going over the fabric with my firewall rather than bendingthe firewall edges toward the prop-just made more sense to me but then again there are probably Piets with flush mountedsheet steel firewalls which is okay too.Mike C.________________________________________________________________________________Subject: Pietenpol-List: forming aluminum

Without heat, you should be able to form the edges around a thin welding filler wire. Just leave an extra 1/4" or so, and start forming with linesmen pliers. It's easier than you think.I did all around the openings for my cylenders, and for the front of my eyebrowswalt evansNX140DL ----- Original Message -----

I have found some discrepancies in the GN-1 plans. Certainly not the first. Myquestion concerns the location of the rudder pedals for the rear seat. If Iput them where they show on the plans I think I will have my knees in my chinand I am not a tall person. If I put them where i think they need to go theywill prevent the support under the front edge of the front seat from extendingto the longerons. I read some where on the forum of concern that if the frontseat is not supported laterally it could collapse sideways. The previous builder of my project planned to support the front seat on a set ofpedestal brackets front and back that give little lateral support. Have anyGN-1 builders encountered this. I am estimating that my rudder pedals frontand back will be 41" from the backrest of their respective seats.Jon CoxwellRemsen NY--------Jon Coxwell GN-1 BuilderRecycle and preserve the planetRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: forming aluminum

Well so much for patience- I couldn't stand to try it without annealing. so I annealedit some and started rolling the edge with pliers and tape over the jaws.it was coming along fairly good. but I decided to trim some and re-anneal androll some more. that wasn't a good move.when I hit it with the torch againI got an instant crack about 1" long in the curve. guess there was enough stressthat the weakening from the heat let er rip.Oh well-I have a pattern and enoughmetal to cut another one. maybe better luck tomorrow.this is tedious workand I am not a patient person.

Skellytown,I am so ignorant about shete medal work that I don't even know how to spellit! But someone sent me the attached, "Bead Wire" and I was able to producetwo cooling ears right. My first one was with .025 and I had a great deal oftrouble making it bend, so I switched to .016 and the next two came outgreat.Gary BootheCool, Ca.PietenpolWW Corvair Conversion, mountedTail done, Fuselage on gear(18 ribs down.)-----Original Message-----

Mikee-In some jurisdictions, what you posted about being "for sale" would be consideredas "solicitation" and you would be arrested by the vice squad ;o)I remember when I first got 41CC and there were some issues with the ignition harnesses.I was at work, Charlie was at the hangar attempting to start the engineand called me on the phone with the news that "the airplane needs a new starter".For a minute all I saw were dollar signs until the joke clicked in myhead. Ever since I replaced the lower harness and all the plugs on the 65,it has started quite readily except when it's hot and I flood the thing. I liketo hand-prop and I like the simplicity of no electrics. To me, it enhancesthe open cockpit experience.The 75 that is now on the airplane is even easier to start, what with dual impulsemags.--------Oscar ZunigaSan Antonio, TXAir Camper NX41CCRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: forming aluminum

Thanks, David! That picture was taken while testing for fit, and adding someother stuff on the back. Since then I have added more support. In retrospect, using dead soft, as Mike C advises, would be a goodidea.....lots of time to do that when needed.Gary BootheCool, CAPietenpolWW Corvair ConversionTail done, Fuselage on gear18 ribs done-----Original Message-----
