This is a British video. Does anyone know where I can get such thing in the USA. I think it is marvelous.
Seems like something you can get made at your nearest metalshop/garage.
FYI, when he says the filter material is secured by "Jubilee clips" he means hose clamps (the type that are screwed tight). I agree with you Katherina it seems like a clever idea.
Looks like a fire hazard to me. Hopefully he turns of the propane before pouring. Also looks like hassle to clean up after wax and slumgum hardens, it will all be intertwined in that filter cloth.
