I was just on the phone with Caleb at Zenith and after describing the problem he claims I should not have any problem with the fit and that I must be putting parts in out of order. My initial question was whether to pitch 20 on the solid rivets was correct as it will likely hit existing holes on the top flange of this rear center spar web. He said not a problem if it did since there's a double on both sides sandwiching that part. I intend to take my vixen file remove what's necessary from the rear center spar web angle to eliminate the interference and allow me to get to bolts, spacers and washers in easily.

I have done 7 of them and no trimming was required. If anyone has any questions they can call me 502-644-8123. Jeff In a message dated 6/7/2010 10:38:44 A.M.

My initial question was whether the pitch 20 on the solid rivets was correct as it will likely hit existing holes on the top flange of this rear center spar web.

In fact, he said you could even cut that flange off but it would of course screw up the spar angle. > > I intend to take my vixen file and remove what little is necessary from the existing rear center spar web angle to eliminate the interference with the top spar cap and allow me to get to bolts, spacers and washers in easily. > > Dave Well, I did some light tapping with a dead blow mallet and it popped into place. So I think thats OK But I may have created a new issue. I saw on the prints that the new rivet line on the top of the center spar is Pitch 20. Are we not using the previous rivet holes on the top of the spar ?? Or is the a new line and the old holes are covered by the doubler? If we aren't using the old holes on the top flange then I'm gonna have to get a new doubler cause I backdrilled the thing from the old holes in the top of the spar Let me know If I need to call Roger and order a part Larry Read this topic online here: http://forums.matronics.com/viewtopic.php?p=300478#300478 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith-list Browse Digests http://www.matronics.com/digest/zenith-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
