From here I do and at the moment you are the perfect guy to help me. I need to know what is in here and some dimensions. I have looked at Christers post here but the tube in the center is much higher on mine and is creating confusion. This is obviously a larger burner. I did give it a run to make sure everything else was OK. The jet could still be enlarged I guess but it looks Ok to me at this stage. The gauze was too fine as I expected and melted. I do not have the pricker mechanism but for now I can live with that. The cover on mine is a bit different to yours and just going on the numbers on the door, I could assume this was an earlier design. This book has some good info on these Lux's and as I did not know until recently, were well used in Australian Railways. (I still hope to find the glass one day. ) This shows a base to help with filling and maintenance. @Lighthouse @Carlsson @Conny C @Bo Ryman
Anthony, It almost looks like if you just placed a piece of metal on top of the gauze on the picture with the flame. Is this the case, or did you actually make the inner burner part that sit around the central tube? If not, you will get a bad result. The inner part is just a sort of bowl that re-direct the jet downwards, and then the gas is re-directed once again upwards as it meets the bottom of the burner, as I try to illustrate in my crudely made hand drawing below. Only difference with your burner from the home made smaller one I made, is that the inner tube (#7737 and 7738 in the catalogues illustration) is higher and protrudes through the gauze on the larger burners, while the smaller burners kept this part under the gauze, which then could cover the entire top of the burner. That lower cover is most likely a home made thing.
This was an experiment using what I had on hand. I made it about 10mm too tall so I have the option to shorten it a bit if needed. Using part of an Aladdin wick lamp in place of the gauze. It did look like it was working too for a while. Then came the underburn so a very quick shut down.. I know what I'll be doing over the weekend. @Lighthouse
Well, it seemed to have worked for a while. I think a gauze with a finer mesh is what you need. The holes from the Aladdin lamp are probably too big, and will allow the flame to find its way below it.
Perhaps the dome heated up, being taller, as you said? ...It is sitting in the hotter part of the flame? I would trim off quite a bit?
I mean that you need a finer mesh or grid than those holes in the ring you used instead of the gauze. You mustn't have too large holes there, because that will allow the flame to get beneath the flame spreader. It's the reason why the safety grid on miner lamps always are under 0.8 mm.
I haven't forgotten about this Anthony! I'll see what I can do tomorrow morning. Last time I tried, I was unable to remove the screw that holds the flame spreader. Letting it soak in some WD40 so it should be good to go tomorrow.
