    I hear you, Jim. I'm really sorry that this has created such a logistical nightmare for you. We tend to forget that there are so many different scenarios where building is concerned, from shops to hangars to garages to dining room tables. I really hope that Zenith has some work around that will allow you to proceed without too much discomfort. -----Original Message----- >From: Jim Belcher <z601b@anemicaardvark.com> >Sent: Dec 2, 2009 2:48 PM >To: zenith-list@matronics.com >Subject: Re: Zenith-List: Re: fuselage mods > > >On Wednesday 02 December 2009 16:49, Rick Lindstrom wrote: >> <tigerrick@mindspring.com> >> >> Certainly makes sense to me, Jim.

I'm not sure what I'll do, but I'm too old and cranky to give up this easy. :-) I slept on it last night - maybe I'll come up with something. I really feel for the folks with dining room tables. I'm at least in a shop, even if it is full of other things. ============================================ Do not archive. ============================================ Jim B Belcher BS, MS Physics, Math, Computer Science A&P/IA Retired aerospace technical manager Mathematics and alcohol do not mix.

    [quote="Afterfxllc(at)aol.com"]zenith is having a problem trying to figure a way to re rivet the uprights in and the rivets along the cabin floor. I know some have had to rivet their up rights at or near the bend and if this is you you are not gonna like the fix for it. I have decided to take the side skins off and re drill all the holes except for the uprights then have the skin repainted. Then my uprights will have nice fresh holes. I am also going to beef up the side skin to .035 and if the rivets on the belly don't work out I will make that skin .040. I don't want a patch job on my airplane and the extra work will pay off in the end. Jeff > [b] The floor rivets line up on mine OK as I decided to replace the whole structure with a new .063" center spar.Haven't got to the uprights but one solution may be to use 4130 of the correct thickness which can be bent with a smaller radius.I also did the pre-fixing /hole lining up while the wings are still off to the new center spar.Cheers Read this topic online here: http://forums.matronics.com/viewtopic.php?p=276007#276007

This will allow the front part of the center spar to be moved back enough that there is plenty of room for the rivets. They will need shims under them so they can still overlap the front upwrights. Another similiar option is to remove them from the inside and replace them with .125 *1.5 material. Then put the .25 bars back on the outside. This way the original rivet holes will line up perfectly. Mike -------- Mike Read this topic online here: http://forums.matronics.com/viewtopic.php?p=276081#276081
