I got the Optimus 930, one of the major lanterns. Beautiful examples have already been posted by everyone, so in this post I will introduce the trouble I experienced and the solution. I replaced the distance ring with a brass one as per my preference. Some people may find it vulgar. The handle looks the same as the one on Optimus200. It may be an individual in transition from 350CP version. The method of fixing the J tube also looks the same as the 350CP version. I prefer the method of fixing the J tube on the late 300CP type because it doesn't come loose more than this individual. At the time of purchase, a problem occurred due to this part. The mantle shines brightly for about 5 minutes after being lit, but as I left it on, it gradually dimmed to the point where I could barely see the mesh of the mantle. When I removed the top bench, the shine immediately increased. At first, I thought that the amount of air intake was insufficient due to the top bench, but since I didn't have this problem with the other 930 I owned, I thought the top bench was not the cause. The conclusion was that the J-tube was deformed, which prevented the airflow from flowing properly, and the mixed gas was burning inside the J-tube, resulting in an incomplete flame at the nozzle tip. Immediately after ignition, the J-tube is cold and will not burn inside the J-tube, but over time it will heat up and cause problems. Therefore, when I removed the top bench, the temperature of the J tube dropped and it was lighting normally. Having identified the cause, I replaced the J-tube with a new one. Since the new J-tube is only available in the later types, I modified the lantern body side and incorporated it. Experienced users may notice this problem right away, but as someone with little experience with lanterns, it took me about a month to notice this problem. Therefore, I will leave this post for the sake of beginners who are troubled by a similar phenomenon in the future. I didn't have a reflector for the 930 and it was too bright to use on my desk, so I made one for use on my desk. It's as simple as cutting a kitchen bowl with a grinder and sanding the surface to a matte finish. The shape is more like a Coleman lantern. My father said, "beautiful lantern is ruined.'' ...Yes, I think so too. The cap is also beautiful. The 930 does not have a pump lock mechanism when moving. There is no problem without it, but I wanted to attach a pump lock to this cute lantern, so I made one myself. I like the locking mechanism for Radius No.119, so I made one by cutting out a brass rod and a brass plate. By making some parts of the ring slightly curved, the parts can be held together through elastic deformation. Here are some tips for making them. Thank you for reading it until the very end.
@ROBBO55 @Sellig33 Thank you. I'm glad it's now lighting up properly. @Tom Pedersen Oops, I forgot to explain. Glass for Coleman 200A. It was about $25 on Amazon. @Mr cod Thank you. In fact, when I look closer, my lantern also has a lot of rust and scratches.
@Jean J There are a lot of glasses for the Coleman 200 on sale, so I enjoy being able to replace them when I get tired of them. Thank you for your comment.
Hello @Camp numao . .Nice to meet you here. That lamp looks beautiful. Very nice modifications and well done. Greetings Stanisław
@Knee Hello Knee. I always read your posts about stoves. I'm glad to receive your message here as well. Thank you.
@Wirdy Thanks for your comment. It's a cute lantern. I also like it. @rollschmidts thank you. When I receive comments from everyone, I feel motivated to try new things.
Very nice work there @Camp numao And a nice presentation too. It must have been some work to fashion out a locking ring for the pump.
@MYN thank you. The process of understanding the structure of the pump holder was a very meaningful time for me. You can make it with pliers and a scroll saw, so please give it a try.
