    Having successfully repaired a lipstick burner with the method ...

    Lipstick burner jet repair


    ... I felt sufficiently confident to try the technique on a coil burner.

    This was the stove, an Egyptian 'Atlas' model

    The jet hole was well worn ...

    ... producing an overly-rich fuel mixture and sooty yellow flame

    I decided this time I'd not sacrifice a burner nipple, but went back to first principles and drilled a 0.3mm hole (the smallest micro drill I had) in a piece of scrap brass

    1301755051-3.JPG


    I then cut a roughly-shaped disc out of the sheet with the hole at the centre

    Meanwhile, I prepared the coil burner. I couldn't get access with a drill bit so had to go in 'sideways' with a spherical burr tool in a Dremel

    The prepared jet disc fitted into the hole ready for silbrazing into position

    Cleaned up and ready to test fire

    Nice blue flame, which got livelier and a bit fuel-richer, but not anywhere near as much as before, so I was happy with the repair

    After firing, the 'ghost' outline of the jet insert was visible, as on the Primus

    Beautiful work, John.

    Next you can try to make some jewelry - I believe you can qualify as a goldsmith.

    Presscall you did a great job fixing this stove and a task i'm not sure i'd aproach.

    May i make the suggestion; when i do such fine work i use filings from my solder stick. this gives a much cleaner solder joint. Just mix the solder filings with the flux by guess and by golly get the right amount. Usually a small pile of filings dipped into with a wet (from your flux) artist bruch (one of those fine point paint brushes) is enough for such a filling. If you need to add more just dip your paint brush into the filings again and apply them to the join.

    Remarkable fettle! Well done. Would you like to tackle a nuclear plant that seems to have some holes in it?

    To those of you who were offended that I should even refer the Japanese Nuclear Disaster in my post, I offer my apologies. To those of you who read it as intended, thank you. The comment was only to suggest that the fettling skills demonstrated here were up to the most exacting demands.

    No offence from this quarter, Sparky. My son and his Japanese fiancee live in Tokyo and they're getting on with things resolutely like the rest of the nation, and with good humour.

    Am I the only one seeing a distinct family resemblance to the 123? :-k And more to the point, would a 123 fit in those gorgeous pots?

    Good Morning, Presscall, and All,

    John, as has been so rightly said, your work is absolutely top shelf, Sir, and well deserving of praise!!! WELL done!!! :clap: :clap: :clap: Many of us Stovies, myself included, "hack" about with our fettling, and it works, much of the time. But, your work, and BernieDawg's, and a small handful of others here at CCS, is so far beyond the ordinary fettle, that the efforts of the rest of us just pale in comparison!! That's what makes CCS such a wonderfully creative and sharing place, IMHO. We have folks like you and Gary, sharing your talents; we have the best leather pump cup maker in the world, my Brother Sefa, giving us cups that are even better than the original versions; we have "body and fender" men, like Lance, who can take a crushed tin stove box and return it to use, through their knowledge and talents; we have several folks that can strip the rust and corrosion off a stove case, and then repaint it to look just like brand new; we have folks like Kerophile and Spiritburner, who create and offer their wonderful heat-proof washers and NRV pips to us all; and we have the most giving, sharing, and talented members here, who come from all over the world!!! I would offer the theory that, if all the planet was embracing the spirit of sharing, creating, and kindness that seems to always be in full bloom here at CCS, our old world would most certainly be a better place!!! :thumbup: 8) :D :D :D :D :clap: :clap:

    Great job, John, and many thanks for sharing your wonderful fettle with the rest of us "Shade Tree Fettlers"!! 8) :D :D Take care, and God Bless!

    Every Good Wish,
    Doc

    Gosh, Doc ... got me blushing there! Very kind.

    Yes indeed, Mike, it's what attracted me to buying this stove, for the pots - they're a perfect fit

    John, thanks, I guess it was only one person who took offence. I work for a subsidiary of a little Japanese company you may have heard of: Sumitomo Corp. I have not seen or heard of any of them with bleeding hearts asking for sympathy. They are a tough people and will overcome this too.
