Well, what did I say? about a week of fettling and prep before fitting? I reckon I wasn't too far off.
Have been out there every night this week and am averaging about two repair plates a night. The nose cone was SH when it went on the car it came off- now it's s being fitted to it's third car. Obviously the GT/J is on its third cone now so you can imagine the combination of rust, sealer, braize annd chisel marks on the mating flanges...
I decided the only way to do it properly was to cut the faces off the cone and make new ones. I have also let in repair plates for the inner wing flanges and tried to straighten the inner wings with a hammer and dolly to remove the ripples.
I have about 4 more plates to do before fitting, at least it will be strong and will keep the use of sealer to a minimum
You can see the state of the unrepaired bit at the bottom here
And thats how it's come out at the side and the bottom on the finished one (I have to dress the weld nearest the chassis leg yet)
