    My Tilley’s metal screen mantle burned up prematurely. It barely lasted a year. I went back to my asbestos one but wanted another metal mantle. I have a propane reflector heater that utilizes a perforated metal mantle. Why not manufacture one from perforated metal? This is the result.

    The holes are 2.8mm or 0.113”
    The metal was a piece of mild steel 0.2mm or 0.087”.

    I drilled the holes, notched the plate ends and tig welded the seam to form a cylinder. The ends were then formed as shown. This was the result. I’m happy with the heat output.

    Well done.
    She’s working very well. It’ll be interesting to see how long it lasts.
    Cheers

    @AussiePete I'm curious as well about the longevity. I couldn't see spending $25 US for a replacement metal one that lasted less than a year.
