Subject: Pietenpol-List: Sources for wing strutsListers, I've haunted eBay, contacted Wentworth Aircraft in Illinois, and several aviation salvage yards and local FBOs looking for suitable used wing struts, particularly J-series Pipers or possible Taylorcraft. I understand thatfailed struts with the problem area at the bottom or inboard area can still be used for a Piet because the Piet uses shorter struts and the bad area can simply be cut off. Does anyone have, or does anyone know where I might find four struts? I could buy the streamline tube from AS&S but that looks to be about $800 at current steel prices.

Wood flier,The Piper Colt and TriPacer had the same lower end strut rusting problem. Wasn't aware you could cut-off and still be usable, be very careful with that idea. The AD that came out in the 70's regarding this these struts should be cked-out before you buy. I had to replace the struts on my ole Colt many many years ago and saw the amount of rust damage they had on the lower end. When you can push a fabric testing punch thru 4130 steel (the original AD's testing method), you gotta worry about the entire strutt.Gordon ----- Original Message -----

The rust is generally on the lower end because that is where the watergathers. If you are cutting the bottom off to shorten it you will get agood view of the inside.In reality though, there are lots of the non-sealed struts out there cheapthat don't have any rust and I would wait for some good ones before I usedrusty ones. Most people get tired of having to pay for the repetative ADand just buy new sealed struts when the old ones are still good.Post a message on www.shortwing.org/forum or one of the Cub forums and youshould find some.Brian KrautEngineering Alternatives, Inc.www.engalt.com -----Original Message-----

We used a varietyof aliphatic amine curatives, 3 in particular, blended in varying proportionsfor different jobs, but in general so that cure rate was as rapid as possiblewithout excessive exotherm. The basic blends were epoxy resin (Dow 362), Hycar,reactive diluent, wetting agent and defoamer, plus silica and fumed silicain the structural adhesive variations, both flowable and thixotropic.Now that I don't do that gig anymore, it's good to know a commercial system existswith the same formulating goals in mind.--------Piet-builder-who-hopes-to-be-flying-next-summerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Sources for wing struts

There are a lot of Piper guys in the Shortwing Piper group that have old strutsthat they would like to sell.I don't have any names right now,but if you can'tlocate some I might be able to get you one or two.I sold my Tri-pacer last month.wepulled the struts and took out the lower fork ends and checked them outgood-found no rust,oiled them and put them back.not sure how the lengths workout-was going to see if they would work on the GN-1 but never got around toit.mine has aluminum struts but I would sleep better if I knew they were equalin strength to the steel struts called for.they may be but I have not seen anydocumentation on them.but several are using aluminum.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
