Subject: Re: Pietenpol-List: Working with UHMWThanks fellows for the pics and thoughtful comments. I just wanted to review thevarious methods before proceeding. I'm actually using pulleys below the seat,then the fair leads with an AN742-12 clamp. Then UHMW as the cables exitthe fuselage. Now I just need to get going on the tail wheel cable routing.Thanks again!JackJack TextorSent from my iPad> On May 21, 2016, at 8:40 AM, Jack Textor wrote:> > > Hello Piet friends.

I see that many attach the forward cowl support to the leading edge of the frontstiffener. The plans call for this piece to be attached to the fuselage a fewinches ahead of the stiffener as indicated in the drawing. Why is this done?John--------John FrancisRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/img_ ... ___Subject: Pietenpol-List: Re: Cowl Support

John;My airplane (and, I suspect, others with a nose tank) does not have that cowl supportbecause the nose tank occupies that space. I have a top cowl piece thatgoes from the front 'instrument board' to the firewall and that cowl piece hasthe front cockpit windscreen on top of it.The stiffener goes across the top longerons where the lower ends of the cabanebrace struts attach to the longerons. I don't think there is anything magicalabout where the 'cowl support' attaches but I could be missing something. Builderswith a wing tank might have a better answer for you.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 power, 72x36 Culver propRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Working with UHMW

Jack,Last week, I met with my Loctite rep on a completely different matter, and duringthe conversation, he mentioned the development of a new adhesive that workswith polyethylene and polypropylene. Since UHMW is in the same family as the other two polymers, it may work; as soonas I get a product #, I'll post it in this thread.--------Tom KreinerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I would not recommend mounting ignition coils (if thats what coils your talkingabout) in the same area as the fuel tank. Spill a little fuel during refuelingor a slight leak in a seam and it could get ugly on start up .Jeff Martin> On May 22, 2016, at 1:39 PM, at7000ft wrote:> > > John> > Since I used a front fuse fuel tank I never added the cowl support.

Seeing the picture of Rick's setup reminded me to mention something to builderswho are installing a nose mounted tank. The way mine is arranged, there is littleor no room to run control cables or anything bigger than electrical wiringfrom the cockpit to the engine through the firewall because the space is sotight between the inside plywood and the fuel tank. And even when you squeaka Bowden cable or tach cable or something else through there, when it gets tothe firewall there is wood framing that you don't want to make a hole throughso you have to offset the cable to clear it and that reduces the smoothness ofthe cable movement. Not sure how to avoid that except to build a notch or offsetinto the side of the tank to allow control cables to get past it and throughthe firewall in a straight line.In this picture- http://www.flysquirrel.net/piets/engine/A75final001.jpg , you can see the things that have to get past the fuel tank on the port side of my airplane. Oil temperature line, tach cable, throttle cable, and carb heat cable. The tach cable is the tightest in my setup because once it gets through the firewall it has to jog over to the tach drive connection and I didn't have much slack in the cable to make the offset. I improved the situation by adding a 90 degree fitting to the tach drive and that helped by letting the cable make a gentle 90 degree sweep instead of an S-turn.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 power, 72x36 Culver propRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Working with UHMW
