Here's mine in use, some previous owner seems to have lost, or modified, the original top.

I have one of these from my grandfather, have used it on small work, will have to look to see who made it, does anybody know what the material is inside, i've just bought anther Mamod steam engine and boiler and was wondering what's in the burner as it looks like it needs replacing.

Martin,

Material, given age of item, asbestos string???

Bottom item (long tapered tube) is a blow pipe, used in conjunction with a methylated spirit lamp to heat small items (eg jewellery) for hard soldering. Could also be used with a bunsen burner to direct a very small very hot flame sideways out of the main flame. Also used for heating precious metal ore for assay on a charcoal block.

Top item is a spirit burner, fill it with methylated spirit and light the wick. The flexy rubber tube with a pretty shaped (ivory?) mouth piece is missing, would attach to the bottom of the curved blowpipe tube.

To use either convincingly you need to learn the wood-wind player's discipline of being able to blow out down the tube using air stored in you mouth whilst at the same time inhaling via the nose.

PS Late to the party as ever, someone came to the door and I was pipped to the post.  Story of my life.

Brought to mind adverts in ME in I think, late 60s, of a small burner device with twin metal tubes for a small heating job. Think it was called "Valtock" or something like that.

Long, long time ago, my Father made up a small meths burner but can't now remember what he used it for. Base was circular (3" dia.??) thin brass sheet with a rising taper towards the middle where there was a round, vertical sided cup, about 1" dia?? X 1/2"?? high, which served as the meths receptical. No idea what that started life as, could possibly have been a light fitting. A large hex brass nut dropped over the top with it's shoulder at the top. A piece of tinplate cut from a can was soft soldered under the shoulder and a wick hole punched in the middle. Meths in the small 'tank' and a length of asbestos string threaded through the punched hole. What he used it for is a mystery after all these years, especially as he made up his own electric soldering iron. He didn't do model making in any shape or form - his hobby was rod and line sea fishing. Point I'm making is, how easy to make useful devices just looking at items and a bit of imagination.

The meths burner in the Swedish-made 'Trangia' camping stove does not even have a wick or absorbent layer (the latter as in the 'Mamod'.

It is a spun or pressed, open, cylindrical cup resevoir with a double wall formed by turning the rim over and back down onto itself into the cup. This creates a roofed annulus, but the roof is perforated, making a ring of small holes. .The inner wall finishes slightly above the cup floor.

It is hard to see quite where the main flames are: on the open fuel surface, from the top holes, or both; but either way it is remarkably effective.

Simmnering or extinguishing is by a loose cap with a simple shutter in its top; though manipulating it can be a good way to find that flames are hot.

The VALTOCK 2000 was a later plated brass version with an extra reservoir attached at the side by a spring clip.

The top and bottom caps were made of aluminium and were notorious for seizing up almost needing stillsons to get them off.

Nearly always found with mollered top and bottom caps, undamaged ones are OK though.

Just had one last week that was a nicely done repurposed ECLIPSE AUTORAM grease gun; shame really as the Autoram is worth about 4x the item!

Cheers, Martin

I have and use one of the Moore and Wright mouth blowtorches like the one in the above thread. I have often wondered if there should be a gauze or some sort of wick holder that is placed on top of the wadding. Mine works fine without, but I would be interested to know if the item is incomplete.

PS I think the M&W code is a 606.

Hello Bill,

Thanks for the offer, but I do have the M&W info filed away. I was working from memory, too idle to get up and check!

Do you know if there is anything above the wadding? Maybe a gauze or something to retain the string / wadding that fills my particular version. Just curious.

When I use mine, I find the flame covers the whole tube diameter, which seems a bit wasteful??

Thanks again,

Andrew.

I will try something like a washer to reduce the flame area.

Thanks,

Andrew.
