Hello all, it has been a while since I posted on this forum, but today I was reminded that, although the classic stove/ classic lantern community can be odd at times, but it can also be fantastic! Let me begin at the beginning. In may this year my user optimus 111 developed a small puncture in its burner. So I made a cry for help here on CCS and I soon got multiple offers for replacements and even for repair of the old one. I got 2 offers for repairing, one from Afterburner, for which I am thankfull that he offered. And I got the offer from Stu (AKA Loco7stove). Now, I was in the great position to figure out the cheapest postage costs. With that figured out I send my burner to Stu. On the 16th I got a PM that my burner was on it's way back. Today, the mailman knocked on my door with this: I quickly opened it and found: After further unpacking I had to get my sunglasses! At first I thought Stu had send me the wrong burner, but after close inspection, I knew it was the correct one. Darn, the burner looks brand new! Thank you Stu for your excelent repair job! If you just had cleaned the part that needed to be sil brazed I would have been gratefull, but this surpasses all my expectations. Again, thank you. It looks so good, that I almost don't dare fire it up... almost Anjoy the fire pics! I have had it running for a good 10 minutes and it runs like new, the solder has hold without a hitch. I'm glad I have this baby up and running again, thanks for saving it Stu! regards, Arjan.
Hi Arjan, your Op. 111 is likely better than new, What a great job Stu has made of the repair. "If you want a PROPER JOB done, go to Stu!" Arjan You should now be set for many more years of great service from your Op.111 stove. Best Regards, Kerophile.
I've had a repair to my 111C burner by another expert, from the pic I got, looks like it came from the factory. I can hardly wait to get the stove going. Duane
Hi! (just today I am a subscriber). I have learned so much at CCS an want to support. I am very into 111; one of my dearest 111T has a burner leak. I do not dear to try silbrazing myself. If anyone can do it; I will pay for it or may be send another item/stove as payment if that is of interest. Thanks in advance!
@IvarS Welcome to the forum, you will find this forum to be very friendly and helpfull. As for your 111T I got an offering from @Afterburner which might be better for you postagecost wise Norway->Finland. I sugest sending him a PM with the question if he is willing to help
Thank you very much @ajvuik - I have already learned so much here at CCS and just had to be a subscriber. good stuff! I will try to contact @Afterburner - it is not urgent, but single burners for 111 are hard to find today I guess, and this is my first 111 ever, so...
Hej @IvarS - can we see your burner where it has the crack please. Is it in a similar place to Arjan's above in this thread or somewhere else? Pictures will let those with experience assess whether a repair is likely to be successful or not. It's probably worth running a wire brush around the affected area to remove loose crud - the better to see what is really the problem underneath.
Yes @JonD and @Afterburner - see attached pics. Not at all a crack, but a small yellow flame visible while stove runs.
seem to excact the same! Your burner is still good I hope? not easy to get a single new burner, and as some good guys here know how to silbraze that seem to be a good fix.
Thanks for the pics! I can't quite work out for myself how they match up. I think that the yellow flame came from the pressure tube to the left and the apparent burning was displaced from the actual source of the leak. I'm looking and thinking more :-)
Sorry; I was not precise enough. Checked it in water. The leak is none of the two on picture above. Please tell me if some of you find this a very small leak / to small to be fixed. It is making the burner wet with kerosene when pressure and stove running. What do you think @Afterburner ?
Hi, the leak is a problem and should be fixed. When the stove is operating you have a small "pilot" light under the vaporiser which only requires a side wind or draught to blow some vapour in its direction to initiate underburn. The leak is likely very small at this stage, and could be the result of either poor original brazing, or perhaps cracking due to differential expansion stresses. Using good quality silver-based baze metal for repair has a couple of advantages: The melting point of this braze is lower than the copper-based braze used in burner construction, so you have a temperature margin before you melt the braze while carrying out the repair. Secondly, particulary with the now frowned upon Cadmium bearing grades, silver based brazes flow easily and are gap-seeking, so ideal for mending cracks or pin-hole penetrations. As with any solder or braze repair, cleanliness is very important. All combustion products and oxide coatings must be removed from the burner surfaces by pickling and abrasion before any attempt is made at repair. The leak zone will also benefit from a pre-clean with the correct molten flux, before any silver braze metal and additional flux is applied. Finally all traces of flux must be removed before using a repaired burner. Here are two links to a good introduction to brazing: http://www.astronomiainumbria.org/a...ca/easyweb.easynet.co.uk/_chrish/t-solder.htm http://homepage.ntlworld.com/bryan.rozier/silver_soldering/Silver_Soldering.html Best Regards, Kerophile
Thank you very much Kerophile! I am impressed how dedicated CCS-members are to their stoves (also others stoves). Really inspires me to continue with my 111`s to keep them up and running. There are too many 111`s in Norwegian garages living a poor life without seeing daylight and beeing used. Guess @Afterburner will do a good job.
Fettling one of recent got 111; anyone knows if one should avoid citric acid bath to get in touch with the burner? I know to avoid brass to long in that water as well as the inside of fuel tank. How about burner? By the way; what kind of metal is the burner and fuel feed tube? @kerophile or @Afterburner knows?
I don't have any experience about citric acid. I have used other methods for cleaning&polishing. Generally I have been too lazy to polish anything maybe because I don't have proper machines nor proper place to do it (yet)... I think that I saw some mention that someone used citric acid to clean burner.I have cleaned burner with steel brush, propane torch and pressure air. My method didn't made burner to shine it only took dirt away. I would believe that burner and it's feed tube is made of brass.
