    Great memories Brian!
    Its a bit of a beast though isn't it.
    There is a fair amount of work to do on it as the pump tube has received a whack and has bent the tank a bit as well I may end up with a replacement tube,but it looks a funny size but that may be the scale of the tank distorting my perception of it.
    What do you reckon on sand blasting the iron work after getting it apart?

    Hi nmp the pump tube does extend from the tank it i am looking forward to seeing it fired up i have never seen one of these fired up in its iron frame,as the one my uncle g#had was in the shed and there was little cause to use it in the 1970's as by then the only work in lead pipe work was repairing, but i do rember him useing his paraffin Monitor blowlamp a few times which i was fascinated in as a youngster,which started me off in the pressure stove's etc

    I think its going to take some time to get sorted I may have a struggle getting or improvising parts?
    I am going to get it going as long as the tank is ok.

    Isn't that a glue pot on the stove?
    From when carpenters used animal-based glue. Bought as dry pellets and melted in a bath of hot water which would have been in the outer vessel.

    The larger 'vessel' within which the inner pot is suspended in another cast ring has no bottom, its there to concentrate the heat from the burner around the crucible.I have one of those carpenters glue pots that you speak of so I know where you are coming from,the picture does not show the arrangement within the larger pot ,the big handle lifts the whole assembly for moving it about the work site I presume Health and safety would love it on site these days,people wandering about building sites with pots of molten metal suspended over raging jets of paraffin can you imagine it?!!!

    Here you are Nick
    Basically it is a long slotted bolt/screw, with the nut attached to the inside of the pot holder.

    I am putting these pictures here with your stove, as I can't thumnail on the fettling forum, takes up too much space.

    Nice and simple I guess the bolt has just fallen out not too big a problem.

    Flame shots are in the flame shot thread started by Kerophile furnace not included at that stage.
    Thanks for the comment I thought some people would not like it too much as it is a bit over restored but with the cast iron you either do it or not there are no half measures.
    This thread should really be in the fettling forum I think?
    Cheers Nick

    Hi, Have just seen this thread for the first time. I have one of these gathering dust (bought by my wife about 15 years ago). Having looked more closely, the London furnace part looks to be in pretty good shape. The Primus tank has taken a battering and there is quite a lot of repair soldering on it. That said it still holds pressure. The burner however is not so good. It has been bent and I cannot get any jet of paraffin through the nipple, which, itself, does not appear to be blocked. The nipple does not appear to be a standard size so I haven't got a nipple spanner that fits, so cannot do much more to it to find any blockage inside. Also the flame tube & its support are missing. So any ideas re a nipple tool, the missing burner bits, a replacement burner or a combination of all three? I would welcome some advice! regards
