April 22, 2005:
(3.0 hrs.) Riveted on the nut-plates for the capacitive fuel
sender units.
|
 |
Counter sunk the fuel-cap attachment ring to accept the dimples in the tank skin. |
 |
Cleco'd and drilled the fuel drain to the tank skin |
 |
Used a Scotchbrite wheel in my cordless drill to scuff up the rivet lines on the interior of the tank skin and the stiffeners. This will help the ProSeal adhere to the parts. |
 |
Inserted the rivets for the stiffeners into the skins and covered them with back riveting tape. |
 |
Temporarily placed the stiffeners in place and then used electrical tape to mask off the area surrounding each stiffener. This will help with clean up after the ProSeal is applied... just peel away the tape and presto, a nice clean line. |
 |
After back riveting the stiffeners in place, I used a plastic knife to create a nice fillet along the edges of the stiffeners. I also dabbed sealant over the top of each rivet. |
 |
Here is the finished product with all the tape removed. |
 |
Since I had plenty of ProSeal still left, I also riveted on the fuel drain. |
 |
And I riveted the fuel cap assembly in place. |
 |
Here is a picture of the stiffener rivet line. |
 |
Here is the mess... lots of MEK soaked
rags.
Notice on the floor a caulk gun. I modifed this gun to squeeze the ProSeal out of the SEMCO tubes of sealant I purchased from Vans. This worked really well. All that need to be done was to grind down the diameter of the caulk gun plunger to fit into the SEMCO tube. |
