Hi Adam - saw your seats at Garry's last week and they are looking lovely, so lovely in fact I nearly changed my mind about how I'm having mine finished...........
Starting with an innocuous repair panel, the only thing of note was Barry had to spend a bit of time with the drill and wire brush on the inside of the car removing the last of the seam sealer. This would have reacted badly to being welded from beneath, and would have produced very corrosive (to the bare metal as well as Barry) fumes. With it all tidied up, the welding could continue.
After that bit of welding, Barry was able to move to the final repairs on this panel for now, the CDI ignition area.
Two sections were shaped up using traditional methods, and then tacked and welded using the TIG welder ....
It's all in the detail. The CDI area has various reinforcements for the fuel filter bracket and the CDI board. Also the CDI cover bracket needs moving over to the new metal, and as a cheat, Barry nicked the old brazed-in engine bay earth point, and welded that whole area into our new metal. Cheeky but effective.
With inner wing work parked for now, we can get ready for putting the floors in for the last time. Everything was scrubbed out, and the main cavities hit with the black etch. Afterwards, the flanges were zipped back off clean, and then primed with Wurth bright zinc primer (the silver).
This is quite happy to be welded, unlike the black etch, but the etch really bites in and dries to a satin finish, so perfect for acting as host to the cavity wax.
The shell left the spit for a moment, and was placed back onto the jig so that the floors could be tacked into place. It's tempting to do that with the shell on the rotisserie, but the odds of building in some sort of distortion are very high. Therefore, much better to pop it back on the jig (all relaxed and unstressed), tack it so that there's no chance of movement, and then return it to the spit for full welding.
