See the attached photo.Does anybody know this plane? It appears to be a Grega with an oversized fin / rudder. The wheels are interesting......I'm trying to find more pictures or who it belongs to.Greg Cardinal________________________________________________________________________________

The handle on mine is 1/8" thick. I bent it in a U, drilled and tapped forthe 1/4" brass rod. with the two capture nuts and the thread in the UI think it's not likely to move anywhere. Just make the inside of the Uwide enough for a nut and maybe 1/4" more just because. Oh yeah,In the final assembly I'll use lock nuts.Clif> Hey Clif,>> How did you attach the bar (or tube) to the U shaped piece on the valve? > Just drill a round hole and tighten down with those bolts?

Like all the others have said, Vinylester. I didn't find it excessively smellyand the layup went quite smoothly. One thing though, get the resin that'sfor laying up layers. There's a finishing resin that oozes out wax as itcures. The guy at the fiberglass store called it "surfboard resin".If you haven't done this before it would be wise to do some practicelayup, particularely edges and corners! It doesn't have to be big, a fewinches in area is fine. The more rounded corners and edges the better.USE PLENTY OF RELEASE WAX ON THE PLUG!!!ClifRemember, every drip or blob in a cosmetic area is going to have to befiled off!

Greg,You're right. That is a Grega with a large tail - in fact, it's the tail off aJ3 Piper Cub. I believe it also has Piper wings. The plane is French (based inFrance). Here are a couple of links to some pages with some more photos:http://tagazous.free.fr/affichage.php?i ... 22085948/I did a little Google searching, and found only French websites, and based on myweak skills in French, I believe the plane had an incident in 2001 where theleft wheel didn't bother to accompany the plane on one flight. The pilot hadto land with only the right wheel. The wheels are from a motorcycle, and the axlecracked, and snapped off upon take-off. The pilot managed to fly around, andattract attention to himself and his problem by wagging his wings. The firedepartment was called, and he flew around to burn off the fuel. When he landed,he eventually ground looped, without injury.Those wheels do look interesting. There was an email address for the owner of theplane (from a few years ago) on one of the websites I found - but since it'sin France, you'd likely need to "parlez Francais" to get some more info fromthe owner.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 30 Sep 2009 00:12:43 -0400Subject: Re: Pietenpol-List: Re: Does anybody know this plane?

Russell,What on earth are you talking about?Aluminum struts rated for 23000 g's !!!I guess that would apply to ANY aircraft they get used on?I'm going to assume that you're joking around - but on the off-chance that you'renot...Other Piet builders have successfully used the aluminum streamline struts soldby Carlson, but I think you're overstating the strength by "more than a bit".Here's a link to the company website:http://www.carlsonaircraft.com/struts.htmlI assume you're referring to the Ultimate strengths listed on the Carlson website.For starters, you want to base any design calculations on Yield strength asopposed to Ultimate strength (Yield is when the part will deform (stretch) andnot return to it's original state, whereas Ultimate strength is when the strutsnaps in two, and your wings fold up, and you plummet to the ground). Secondly,those strengths are listed in PSIs (pounds per square inch) not Gs - Believeit or not, those two things are NOT related.Bill C.PS No need to boil the aluminum struts.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 30 Sep 2009 01:54:43 -0400Subject: Re: Pietenpol-List: Re: Air Camper load rating
