Could be time to cast new gearbox casings, if it has been made before it can be made again.Oyster 49 wrote:The more I think about it, I doubt that gearbox is repairable. Just my opinion for what it is worth. If welding did not work, is there enough metal to be able to machine out to take a bush with the internal left hand thread, and then make a new end cap? Extreme difficulty!
It can be repaired, if you look what they are doing in the states, it is possible,
Could be time for you to to buy a lathe Oyster.

I personally would mend it with melted down Land Rover, just to add to the iconic status.
I must try casting Birmabright, it was all the rage in the thirties, they even made boats out of it.
Do I need an early OA to restore ?
