They were fragile coolers. The tooling was very expensive for this kind of cooler but with large production made it feasible. If your coolers are bar and plate cores, how are you going to have headers and tanks? Gled
    I was wondering what the original process was called , but you hit the nail with how fragile they are , more to be revealed as we go along .

    Update ; the threaded ends for oil line attachment are machined out of solid ali billet , threaded top and bottom . The idea is that we have made the top thickness at the mount location on the reservoir 8mm thick , we indend to thread the ends into the reservoir top then tig weld around the base giving real guts to the fitting and security when buttoning up the oil lines now and in future .

    Out of interest does everyone interested want both fitting sizes (69 /70 and 72/73 ) available or has everyone migrated over the the larger sizes ?
