This was a relatively short night dealing with tank sealant.  My plan tonight was to finish the two outboard ribs, but I didn't quite make it.  The stick you see below has been one of the most useful of the tank sealant tools I have.  This stick is nothing more than a homemade plastic stick with 45 degree bevels at each end.  This stick is about the width of the tank rib flange.  I put a glob of sealant on the end of the stick and spread the tank sealant over all the rivet holes.  I ensure 360 degree coverage around each rivet hole in the skin and a relatively uniform amount sealant along the bead.  Very simple, yet works great.

Below, I installed the tank vent AN fitting (ELL) and torqued the nut to 55 in-ibs with a crows foot attachment to my torque wrench.  Between the rib and the fitting nut, there is a spacer washer so that the nut can be tightened down to the fittings threads.  As with all my tank sealing activities, I fully encapsulated the spacer washer and AN fitting nut.  I also (not intentionally) had tank sealant on the threads under the nut.  This made the nut turn fairly hard.  One thing is for sure, this will not loosen up under vibration.  I just hope that it doesn't leak.  To protect the rear threads, I did have vinyl electrical tape over the threads and the opening.  It sure makes easy work of sealing as you don't have to take toothpicks and clean sealant out of the threads. 

Don't make me explain how I know a toothpick will get in between the threads....

What is wrong with this picture????  Give up???  There are actually two extra holes in the rib (one on each side of the larger tooling hole).  Before realizing that there was a T-410 reinforcement plate that is riveted to the forward part of the outboard rib, I started fabricating a smaller plate to cover the tooling hole.  Oops, didn't need it.

I seemed to use alot more sealant on this rib than I did on the other tank ribs.  I believe that is was in the neighborhood of 60 grams.  I believe on the other ribs, I averaged right around 35 to 40 grams of sealant.  Of course, the reinforcement plate did take a little extra and I also heavily placed that gooey stuff on the leading edge of the tank.

Just another picture of the results of my tank sealant torture ritual done tonight.

Below, you can see the inside of the tank on that outer most bay.  Everything looks pretty good.  I kind of wish that the vent line sat a little higher in the tank that it appears here.

Tomorrow, I will see if I can talk my wife into helping one more night sealing the tank.  She is losing her interest in helping on the tank in a hurry.  She did tell me tonight that she would take the financial reimbursement equal to the cost of a new BMW convertible so that she could go on a spending spree for her quilting hobby.  Thanks Dave P. for giving her the idea on the BMW and $$$$ thingy.
