UKC

I lost mine    Its about an inch diameter wire mesh circular/disc shaped

I contact jetboil they don't supply that part, 'have to buy a new burner'  Anyone ideas of how to fabricate something simila or adapt something , -  I cant just stuff wire wool in there as it'll burn, i guess if someone has a defunct jetboil one i could repurpose that ?

cheers

Something like this may work?

After asking the same question on here this was my solution, basically as suggested above just retrofitting a few discs of mesh bought online.

It works, although getting the top layer tight enough not to fall out in transit is awkward. However for what it cost I have plenty of mash left for extra discs if/when required.

thank you both, UKC delivers   so frustrating
