It has been a while but have now reached another mile stone on the Sd50 restoration.
I have now successfully formed the ali insert piece (by hand) that will fill the missing chunk of casing on the tail fin, which is cast Mag Alloy. As we discussed in an earlier post, welding is near on possible without it catching light!
Once I have replaced the cheese head screws which locate into the main bomb casing (I am having to use spiral inserts as nothing is left of the original thread) then I plan to use a couple of ali L-brackets and a pop rivet into the tail fin all along the bottom of the insert piece. Then I plan to fix from the outside using counter sink rivets, this should hold the repair piece in place. Then I will use liquid weld to fill in the gaps, maybe a bit of filler a quick sand down then hopefully if it has gone to plan I can paint the area which I plan to blend into the original. If that doesn't work I will repaint the whole thing.
All I need now is the blank for the nose, the lifting eye, then the job is a gooden!
