    Like the original Mission Impossible opening, 'your mission Jim, should you decide to accept it' is to fix the rusted steel base on a Coleman 168K fount.

    Oh how I feel frustrated that a perfectly good and solidly made Coleman brass fount should wither away with a steel base. I suppose we should be happy they have lasted 80 to a hundred years in many cases. BUT not in this case and my poor 9 39 fount should be junked but I am wondering if there is an alternate solution. I may even buy shares in a company that can fix it.

    Ok so I am only half serious but I have repaired one tin plate hurricane lamp by soldering a plate over the base. Not really great for use if the rusting base is still there. Probably not ideal for a pressure vessel either.

    I am wondering if it is possible to cut out the bad base and solder in a replacement base though I imagine an engineer might say it wouldn't be good enough.

    Has anyone else fixed a bad base for usage and I am not talking about a liquid polymer type internal solution but a physical solid brass fix me up for the next hundred years.

    In the bottom picture I have started cutting the base out but I need a longer jigsaw blade.

    I really hate losing a fount but I know, maybe this is it.

    Yours truly

    Ok so I have opened the base up and I am somewhat pleased that there was a fair bit of good metal around most of the rim except where it had obviously been left on its side in some former life. A temporary fix of soldering over the damaged rusted edge may well have worked. Visually with a flashlight what I saw was a good amount of rust occuring which may have been treatable but with the prominent hole on the rim added I still prefer replacement or a more permanent fix. I need complete confidence for lighting these things in front of friends and family. So now to continue the problem resolution. 20251020_150917.jpg

    Watching with interest to see what you come up with Iain.
    I have a similar situation with this Summit 266B

    I have acquired a pot with similar dimensions but haven't attempted the transplant surgery, yet.

    Hi @Sedgman
    Think you got a tricky repair there.
    The steel base is kinda crimped by the brass font sides more than like soldered as well.
    This is how i would proceed.
    I would chop the base out maybe leaving 6mm of the base in place.
    Now you have to remove the remainder of the steel base from the side in the crimp. I think this could be done by heating the crimp with a torch till solder melts then bash it out with a hammer and screwdriver font upside down make it easier. The rusty steel needs to go so you can solder in a new base plate.
    Sèe what you think
    Cheers pete
