    Picked this little blow lamp up at a antique shop this morning and was curious if anyone had any information about it. Would the fuel be alcohol or petrol?

    It is a gasoline (naphtha) lamp.

    There is information on these over at CCS.

    Cheers

    Thanks Tony

    I was going to go out to the garage and test it but it's -16 out so it will have to wait.

    I would be inclined to replace the filler cap seal first. Chances are it has gone hard and it could leak petrol/gasoline fumes which are quite flammable.

    Nice find btw. It's not often you find a complete one with the flame tube.

    Finally made it out to the shop, the solder blob on the side turned out to be a bad repair of stress crack. Might try tig welding it if I can find some 1/16" tungsten if not i will hard solder it.

    Soldered and cleaned up, I will test fire after it's polished.

    How do you finish the solder that neatly? File/sandpaper etc or some other trick?

    I file the high point of the solder until I'm starting to break through at the edges then wrap 400 emery cloth around the fine and finish with that.

    I have one of these. It isn’t very powerful, but useful for some small jobs.

    I had to make the flame shroud for mine.

    Cheers

    Great to see it works especially after such a fine soldering job.

    It must be a great feeling of satisfaction when you got the blowlamp back in working condition.
    Very neat soldering and finishing.

    A good job but if that is a solder repair to a petrol blowlamp I suggest you do your first trials outside, I recently overhauled a primus 71 stove, ie a petrol stove, I call it my miniature volcano, lighting it can be quite exciting.

    Hello Tony!

    Please help me! I bought such a soldering lamp this weekend. You don't have a flame tube. You wrote that you have already made a flame tube. Please describe its dimensions.

    Have a nice day! Thanks.

    I posted the dimensions of this little torch back at CCS many years ago.
    I'll attach the same picture below, and the entire topic is found here.

    Is it common for a fount to pick up just one major stress crack?

    They are a great little blow torch, I run mine on shellite (Coleman fuel). Good for small delicate jobs and think jewellers in non electric power areas would have used them.

    Glad yours was repaired.
