    In an earlier thread I showed how I was using a carbon felt disk as a heat shield because my Svea 123R's windscreen was missing it.

    While cleaning out the basement I ran into an old sales award and realized I could use the brass plate from it to fashion a heat shield, so that's what I did.

    Started by marking multiple concentric circles, about 1mm between each, on the brass sheet. That would help with the fitting as I would always have reference circles visible as I kept trimming down the size until it fit.

    Thickness was similar to that of the the windscreen. Didn't break out the micrometer to check in effort limit myself from being overly fussy.

    For the burner hole, I marked a 50mm circle, drilled a small starter hole and then used a jeweler's saw to cut it out.

    In the end, the shield fit a little tight but since I got it in I'll probably leave it rather than muck around with taking off a tiny bit more material from the outer edge.

    I bought this stove for use, not for show, so even though my DIY lacks the additional hole and slot it's good enough for my purposes.

    Looks good. And, plenty of brass left over for the next project. Also, tight is good, that is the way the originals fit as well.

    Very good. A right clever fix, I'm filing that one away for future reference.

    Thanks everyone. At least it looks right now. A Svea deserves to look right.

    GREAT JOB! I always admire work that has been done by hand. My entire life, I've never had access to "professional" tools, only hand tools and have always tried to craft things with what I had on hand. It's not always turned out as well as your project! :thumbup: :thumbup: On your Svea repair!!

    Great job, real McGyver.

    Just one detail you might consider, drill a hole over the SRV (filler cap opening) so if the tank get too hot the gas will exit the top and not hit the plate and exit all over the ground.

    Also check you safety valve and the opening from time to time as crud in the opening can prevent the valve from working, then you will just have a Swedish Grenade!

    Clean the opening, then when all is clean and dry, test the SRV by sticking the back end of a 3/16 inch drill bit on the SRV and push. If the SRV moves with little effort you don't have a Swedish Grenade.

    F.Y.I the two slots were for the pot handle and the pricker tool/primer cup.
