It`s nice to hear from a happy customer! :thumbup: I recently received this pic, from Germany...... Most of my widgets leave me, never to be heard of again...... Sometimes, not even a thankyou! ::) This made a very pleasant change. :) David D |

Dave SD Ahhhh! How curious .... just read all the way through this post, so what is the reason for the breather holes? The reason I ask, is donkeys years ago I had some dealings with a hot air engine with a similar heat source. This used to flare up after some minutes use, because vapourised Meths was venting through the breather holes, and igniting. It was not my engine, the owner asked me to block the holes. I refused on the grounds that it would not stop the effect, just make the consequences worse. It was reduced by only about 1/5th filling the tank. By the time it got hot, it was empty. Hopefully. Not a home made job, it was some commercial tinplate 'Mill Engine' thing. Don't remember who made it. I surmise that these burners don't exhibit the same antics... or do they ? Assuming they use Meths .. These holes must either be to release any internal pressure, or to allow air in to replace used fuel. Can't see any other reason. Hmmmmm... interesting .... Where do you fill them ?? Can't see any filler cap. Dave BC |

Dave, To fill, pull out the wick holder, as in 1st pic. It is a push fit in the tank....... These meths burners are well known for flooding, when filled enthusiastically! But, with the tank 3/4 filled, all is usually ok. Most kids learned, before Mum spotted the scorch marks...... The vent holes are placed there so the gasses are ignited by the wick, when safely under the boiler. There was an early (Japanese?) burner, filled & vented through the hollow handle, which flamed like a blowlamp when in use! Not really safe for kids to play with. They didn`t sell many...... ::) David D |

Dave SD The one I was involved in looked much like the centre one from German Pics. The filler cap was in bottom RH corner IIRC, wick about where furthest one is. Not a hollow handle. Could have been Japanese tho. Dunno. The burner did not seem to be from the engine. There were 4 pressed lugs, as if the 'proper ?' burner had a flat base, to slide into. Also seemed too high. Anyway, went well after cleaning the carbonised oil off the piston rods. Did Mamod or similar make them? This one had a black base, and a 'Brick' painted and embossed smokestack wotsit. Can remember that bit. IIRC base would be about 9" square. Dave BC |

Dave, That sounds like a Marklin, or maybe Bing, pre war hot air engine, with a non original burner........ They show up occasionally on Ebay. There`s a couple of little pics on Google...... "hot air"....... My pal Roger had his dad`s, 55yrs ago....... Never seen one yet, that matches my memories of it. Sounds as though "your" burner was getting too hot. Not ventilating properly, as it was too large for the space available. David D |
