Help! I just got started and am already in trouble. I was puting the SS7 wing spar I-beam inserts into the wing spar tubes. 3 of them went in just fine with no trouble. On the 4th one it went in a little tighter but not too bad. I could push it by hand until it got in about 1" inside the end of the spar tube. I then probably did a foolish thing and tapped it in a little farther with a stick and mallet-not too hard but hard enough that now it is stuck and won't go in any farther and I can't seem to tap it out from the other end. I am afraid to beat on it too much. I have tried the clamp method shown in the manual to egg shape the tube but it does not seem to help. It has probably galled itself (soft aluminum on soft aluminum) and semi-welded itself together.

What should I do now?
