Hours Today: 2.8 Project Total: 650.1



Since I was a little worried about the flexing our longeron yoke was experiencing I decided to hold off an squeezing any more of the AD6 rivets for now.  So, I went on to something else.  Welp, when I tried to pull the pins out holding the yoke to the squeezer the pin closest to the plunger wouldn't budge!  I had to force it out!  Once I got the yoke separated from the squeezer I was able to see that the pin hole was warped.  The yoke showed stress signs below this hole and you could physically see a bend in it... not good!  I had never tried setting anything over an AD4 so I wasn't sure if I had tried to ask to much from it, or if the thing was defective.  I talked to Shaun at Isham Tools (where we got it) and he indicated it shouldn't have bent, and offered to send us a new one.  Nice service!
(18-5 step 3):  So… on to other things now!  I installed the no-holed yoke on the squeezer and worked on setting all the nutplates for the fuel sender units.  Basically I just coated the mating side of the nutplate in proseal, stuck it on the rib, installed a cleco in one hole and squeezed a rivet in the other.  Pulled the cleco out, and squeezed a rivet in the other one.  The do it again for the rest of them.  After that, I used the same process for the vent line anti-rotation brackets, but after trying to set one of the AD4 rivets with the no-hole yoke and being a little skittish about it bending (ok, I was a little gun-shy having already ruined one expensive yoke!) I decided to just glue them on tonight and only secure them with proseal.  While I was at it I also glued the strainer fittings on.  We should be getting our new yoke soon so we'll set rivets in these shortly.  For tonight though I just used the remaining pookie to cover the shop heads of all the nutplate rivets.
