Evening, All, Many years ago, a friend here at CCS sent me a Coleman 527, which was in need of some love and parts. In addition to need a complete refinishing job, it was missing it's tiny roarer flame spreader. Well, that little guy went into a box, and even though I would "find" it, now and then, and "think" about doing something with it, nothing even happened. But, now that I have three Pigeon Ignus stoves, I decided to try the silent cap from the worst of them, on the little 527. The burner bell is misshapen, so the fit wasn't perfect. And, I had to prime the burner with a torch, as there is no spirit cup on it..... yet! But, here's how it went, after a few coughs, fits, and starts: As you can see, though not perfect, it really isn't horrible, and I think this combo has some future to it. I need to reshape the bell, and affix the silent cap in place with some wire, which will not be hard. I also have to come up with a spirit cup of some kind. Then, who knows, maybe this little guy would be a fun user for tea on day hikes!!! Thanks for giving this a squint, and God Bless! Every Good Wish, Doc P.S. The last two photos show as close to a "simmer" as I could get, and this was with using the cleaning needle to partially block the jet. More testing will have to be done later, or course.
