Hi all

I have just started to do an initial fit of the fuel tank and leading edge ribs into the skins and found the ribs to be extremely difficult to seat into the nose of the skins, at least to have the holes line up for the clecoes.

I have fluted and straightened the ribs, and still they appear to be far tighter than the vertical stab ever was. Can't imagine throwing tank sealant into the mix.

Any suggestions or words of advise????

I was in the same situation as you a couple months ago. These do seem to be the tightest fitting ribs so far in the whole build. The easiest way I found to get them in is to start on the top side leading edges and just start a few clecoes in them. Then flip the skin/ribs over and work them into place adding a few clecoes on this side. Flip back over and add a few more. Do a few at a time on each side all the way to the trailing edge. I sealed my first tank a couple weekends ago and will do the second tank this weekend. They do start to fit a little easier when you get them drilled and dimpled, but still tighter than any other ribs yet. If you have a second or even a third set of hands helping when you seal it's much easier. I had two other guys helping me out when I did my first tank and I cannot even imagine doing it by myself--I know there are guys that have done it solo but extra hands is always better.

Good luck,
Bill

Another thing to do is to trim the rib nose flange edges. The flat flanges need help to conform to the round nose skin.

Snip off the flange corner then smooth with a A scotch Bright wheel in a air grinder.

Too much force fit will deform the skin.

Thx Carl. Never thought of taking corners off the little flanges. I will take a look at that.

Regards, Rick
