Hello Noel;

    I use MAPP gas in small bottles with one of those hardware store
    burners, like the propane torch type. I only use it for annealing
    large articles and sometimes for casting. Supposedly it's a little
    hotter than propane. I can't see why it wouldn't work with any
    combination of oxygen, force air, inspirator burners, etc. 

    p.s. Sorry to hear about the plantar faschiitis, I had that once, it
    was miserable, took my half an hour every morning to be able to put
    my weight on my feet. Very painful. 

    As for that post on removing LOS from inside bezels, you are
    absolutely right, and I caught that some posters weren't answering
    correctly. I was going to suggest those little fiberglass scratch
    brushes, which work great, but I hesitate because tiny fibers of
    glass floating around in the air are just about as bad as asbestos.
    Better a little end brush in a flex shaft handpiece with some bobbing
    compound.
