    So now that I have the fettling bug I've decided to have a go at a bigger challenge. Manager to acquire this Kayen heater. Fount really dented and missing the whole burner. I'm planing to give the fount the ice treatment as a start.

    That is a pretty big dent. The volume of water expands by about 9% when it freezes. It may take more than one ice treatment to get the dent out.
    If you go the freezing route, consider first freezing a 1" or more layer of water in the bottom of the fount. This will protect the bottom lead seam of the fount.

    Another option is the heat method:

    Fill the fount with chilled water to a little below the dent. Use the pump to pressurise the fount to moderate pressure. Then play a butane torch around the edge of the dent in a spiral motion as the dent comes out. Not too much heat, and the water must never boil. The process should only take a few minutes.

    Thanks for the tips. I know it will be difficult to repair the dints but I have time on my side. Finding a burner will be a challenge I expect. Might have to make one from scratch I expect.

    A Tilley burner will fit it. I might have one in the shed.


    Cheers

    If you made an adapter to connect the font to a pressure washer you could pop those dents out. I've seen guys do it with dented two stroke expansion chambers.

    So the ice wasn't going to get these dents out. I gave up on that,fired up the oxy torch and took the bottom out. That made it easier to peen it out closer to the original shape. Then I spun it in the lathe and kind of rolled the bumps down from the outside. Next I will place it in an external jig and do some fau metal spinning from the inside to get the shape back that I stuffed up with the outside roller.

    Can someone help me with some dimension sketches of how the burner goes together though? I bought these parts via bay of evil. But I don't have any idea the structure or
    dimensions of the rest.

    Found some pictures over the web and look like you still need some parts. Also get a lamp gallery and use it as lamp/lantern

    The old Tilley and Kayen burners are a pretty complex piece of engineering.

    Or

    "modern" Tilley with pressed brass parts and lighter materials.

    Thanks guys. I can see the old design could be fabricated on a lathe but I'd have trouble with the large threads. I will think on it a while. Maybe I will surprise us all.

    The complicated bits aren’t shown in the photos - all air the holes etc.

    Looks like you have given it a work over,(it may pay to anneal it as you go.)
    I have seen a couple of these with random stress cracking .
