    Whilst still in "Blanchard fettling mode", I decided to have another look at my Blanchard 1000. The tube which extends downwards from the burner and through the spirit cup heat acting as a heat sink, is broken off and needs repair but I've noticed that the burner is slightly different to others I have.
    On this particular burner, the sleeve in the centre of the spirit cup extends right up to the burner head and is silver soldered in position but what is left of the heat sink is not fixed to the spirit cup. I've also noticed that the spirit cup seems to be made of a lighter weight brass.
    To my mind, it seems unlikely that it was made like this and that it is in fact, a repair or modification. Can anyone confirm my suspicions please ?

    Hi Pete,

    Thanks for the info. Yes, I have the inner burner tube, nozzle and mantle holder - just need to find them again. Why they got separated from the lamp, I'll never know. I did come across them a couple of weeks ago when looking for something else but of course now that I need them, I can't remember where they are.

    I'll see if I can get a piece of brass rod silver soldered into the broken vapouriser tube to seal the end and leave it just long enough to stabilise the mantle holder.

    Nice donut by the way and an excellent restoration.

    Henry.

    I hope you get there. When Jim was here we tried for maybe three hours to get my table lamp working. Everything is there, we fitted a new pricker and the jet is OK but it just refused to run. Odd because I know very well how to make lamps work and Jim is a Blanchard specialist but between us we had no clue why it refused. So for now it is ornamental only which really burns me up because I have fettled 7 Blanchard burners but this one has defeated me. ::Neil::

    Henry, if the top half of the vaporiser tube is sound you can get away with just silver soldering in a new bottom half that passes through the meth cup, I can send you a new one if you want.

    Re Neil's lamp, I think the problem we were having was it didn't seem to hold pressure, but with no obvious signs of a leak. we will have to have another look at it. Jim

    The lamp will have to wait. Got a trapped nerve and my right hand no longer works. Getting very hard to type and hold things. Fettling is beyond me for a while at least. ::Neil::

    Jim,

    Thank you for your offer of a bottom half but I'm not sure it's that simple. I took out the plug at the top of the vapouriser and using my sandblaster, really cleaned out what remains of the tube. With the aid of a single LED "bendy light", I examined the inside of the tube and it appears to be one piece which passes through the fuel inlet pipe to the burner head where it's silver soldered in place.
    The construction of the burner doesn't allow much room for fine work and I'm a little worried that the heat needed to silver solder will loosen adjacent joints and possibly cause a leak.

    Henry.

    you can drill out the whole vap tube henry and solder in place a complete new one i done this 2-3 times but i found it difficult like you said 3-4 joints to solder in hard to get at places and all have to be gas tight.
    i only done them as they appeared to be cracked leaking gas at the top end
    i used different melt temperature silver solders for different joints

    Hi Pete,

    I hear what you say but please bear in mind that I haven't yet acquired the skill needed for such work and I'm not sure I want to be honing my skills on this piece of history.

    I don't suppose you're open to a bit of contract work ?

    Henry.

    So do I. It's a right pain. I can still grip but got no fine control. Hard to type and work on images. I suspect it's permanent though. Doc just gave me an Hmmm and no further comment. ::Neil::

    No worries but you can't blame me for asking. I guess I'll just have to grow the necessaries.

    @Mackburner, let's hope the trapped nerve, un-traps itself ASAP.

    Henry.

    Following on from my original post, I cut off the damaged section of the vapouriser tube and silver soldered a short length of brass rod into what was left of the tube. I haven't got it as straight as I would have liked but it works so I'll leave it as it is.

    Time to play. When the complete cowl is fitted to the burner, there are no flames coming out of the spirit tube.

    The lamp came to me without a glass and the wire to hold it in place and a broken "new type" needle.
    So I borrowed these items from a model 1128.

    Many thanks to Jim Currie who offered to supply me with a new vapouriser tube and also to Pete Sav for all the technical advice he gave me.

    Henry.

    @JEFF JOHNSON @WimVe , Thank you. I've made a wire holder for the spare glass which I'm sure I have it but still need to make a fastener for it and I also need to make a cleaning needle so that I can return the "borrowed" parts to the 1128.

    Henry.

    Thanks Phil.

    The hardest part for me, was building up the courage to tackle the soldering. As can be seen in some of the images I posted, there's not a lot of room to spare. Let's hope my success wasn't just "beginner's luck".

    Henry.
