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.
Hello Doc, Quite a decent result!!! If you're looking for a spirit cup, I can recommend the copper plumbing end-cap. They can be found in many sizes, be bought for shillings, and drilled to fit. Then you can silbraze them to the riser, or silbraze a small tube to the hole. I did so with a Tilley R46 (to save having to use the clip,) and it worked well. Sadly, when the generators needed replacing, my "Spirit Cups" went out with the old ones. I have the new cups, but have yet to get the tubes silbrazed into them. Just a suggestion. Best regards, Mike.
Hi Doc Why not just use a Tilley type pre heater that'll clip on for just the job , or a fork type like the early French petrol lamps used easy to make from some stainless wire & glass fibre rope. Doc does the cap have any inner cap & venturing plate fitted If not give me a pt & i'll see what I can bash together Stu
Morning, Mike and Stu, Thanks, Gentlemen, for two very excellent solutions to my spirit cup needs!! I'll take the path of least resistance, first, and try one of the NOS Tilley priming torches to see if it will work with this setup. But, the idea of a copper fitting, with a hole drilled in it, and a small length of copper tube silbrazed into it, would also be an eloquent solution, too! 'Course, I'd have to LEARN how to silbraze, though.....!! It's a skill I have yet to undertake, but one that I really should investigate. Thanks to you both for your great suggestions!! Stu, the cap does have a form of inner piece, and also a venturing pipe. I'll snap a few photos, so you can see how that setup looks. Thanks, again, and God Bless! Every Good Wish, Doc As you can see, the cap is filthy, and some of the holes either plugged, or occluded. Either way, this cap needs a good cleaning, and the holes need some light reaming to clear the all up. In the meantime, I'll be seeing what I can do to straighten the burner back back into something closer to the way it should be. Hopefully, when all is said and done, this may be a fun little combination! Thanks, again, Gentlemen!
I'll wager if you used the generator nut from a M1950, it will take care of the problem of preheating, as the nut has a preheat cup built on to it. I did the same thing on my 530, works great! Murph
Hey, Murph, Yet another good idea! I'll check to see if I have a spare M1950 from which to borrow that part. Thanks, Murph! Further reports to come...... Take care, and God Bless! Every Good Wish, Doc
Looks great Doc!!! Glad you brought it back to life!!! Getting a old stove running after so many years of non use is a lot of fun. Dan
Howdy, Dan, Thank you, very much, for having kindly sent this little 527 to me, quite a long time ago! I've tried a couple of small caps on it, and so far, the Ignus cap seems to work the best. Once I clean that cap up a bit, and ream the holes out, I think it will work better than the photos showed. I'll also wire it in place on the burner bell, which will be easy, as the Ignus cap has two holes in the top for just that very purpose. Thanks, again, for the nice gift of this little Coleman, Dan!! Take care, and God Bless! Every Good Wish, Mark
Update: Hey, Murph, I checked out a M1950, and found that, whilst the generator nut did have a spirit cup attached to it, the nut is much too large to work on the 527. Still have to check out the other great suggestions for retrofitting a spirit cup to this little guy, though, and will report back here, when that happens. Take care, and God Bless! Every Good Wish, Doc
Doc, I wonder if the 523 priming cup would work or just be more of the same? Break out the Sil-braze and tubing cutter! AR
Hi Doc, Check this out. I just received a spirit cup for the Optimus Ranger 99 stove and this spirit cup fits pretty good on the Coleman 527 medical stove. As can be seen in the pictures there is only a small gap but it sits evenly on the generator nut. I purchased the from Shirlene and again this spirit cup works great. Here's the link. http://www.ebay.com/itm/Optimus-spr...-Stove-Ranger-99-Free-shipping-/271774888110? I hope this may solve your question. Cheers, Norman
Hey, Norm, I just sent you a PT about this, and again wanted to thank you for this excellent suggestion!!! As I told you in the PT, I bought a couple of original ones from Shirlene quite a few years ago, and when I dug one out just now, it dropped down onto the riser just like you show in the great photos you shared here!!! I am really looking forward to giving this a try!! Thank you, once again, Norm, for this great suggestion! Go to the head of the class, please, and two pieces of cake, or two beers, your choice, for your help!! 8) Take care, and God Bless! Every Good Wish, Doc
Glad you got it all sorted out, Doc! As to the M1950 nut, it was just a educated guess on my part here, thought it might be worth trying. Murph
Hi Mark, I sent my 527 to Gary along with one of my PuppyDawg caps. He altered the cap just a little and now the PuppyDawg cap works quite well for this stove. My thanks go to Gary for all of his help with this conversion. Couple of pictures of the stove and fount with spirit cup. As can be seen in the pictures the PuppyDawg cap legs for trimmed down to fit into the burner bell and the OD was trimmed so it would seat onto the lip in the burner bell. I've used an Optimus 99 spirit cup for preheating. It fits nicely over the generator, and works very well. Here's the stove up and running. At first lighting there was quite a bit of yellow and this got better as it ran, but I decided to do a jet change with pretty good results. One can get a very nice simmer using the cleaning needle. The 527 isn't the easiest stove to fuel so I have several of these bottles. One is for Coleman fuel and another has Kerosene/Paraffin. The beauty of these bottles is you be quite precise with the filling and if you over fill the fount it is quite easy to remove the excess fuel. I got this idea from Kerry, kerry460. Thanks, Kerry for the great idea. Now all I have to do is figure out some sort of trivet for this stove. I don't have the original pot support. If anyone has any ideas I like to hear them. Cheers, Norman
Hi, Norman, Thanks for sharing your refitted 527 with us here! For a pot support, you might want to copy a couple that were offered with various versions of the Borde. Check my post in the following link to see an original folding pot support from Borde, that could be designed to work well with your 527. https://classiccampstoves.com/threads/12982 And, here's a cook set that I think was originally offered by REI, when the Borde was first introduced. And, here's another idea, one which I used for a bit, back when I first saw that the Borde was offered with this Ranger type cookset, at one time. I had to do a little cutting and shaping in order for my Borde to fit into this setup, but it did work quite well, with only one caveat, about which I'll tell you in a bit. And, now, the caveat: This combo WILL scorch whatever is underneath the cook set, so be VERY careful when using this setup!! Please note, in this photo of my first kero 111 burner (Thank you, Ian M.!), after I'd swapped it out with the gasoline burner of a 111B stove, that the redwood deck rail upon which I used to test stoves, has a nice, deep scorch mark burned into it. This is easily visible in the top left side of this photo!! Sweet Bride was not a happy Lady after she saw what I'd done!! But, after only a short period of administering beatings to Ol' Doc, she did forgive me, and I was thankful for that! In any case, I think you can easily fabricate a pot support, or modify the Swiss Ranger set, or even modify an Optimus 88 cook set, to go with your Coleman 527. I'm going to do the same thing, once mine is working up to snuff. Congrats on getting your Puppy Dog cap modified to work with your 527. I have an early hand-made Puppy Dog cap that Gary made and sent my way, and I'll try that one on my 527, too, just for fun. Talk soon, and God Bless! Every Good Wish, Doc
Hi, I decided to make a pot support with trivet, so here is what I used. 4 Carriage bolts 1/4 in X 4 in. 4 nuts 4 washers 4 lock washers 1 trivet. The trivet can be found on Amazon. This trivet was featured here some time back. Here it is all together. I added some feet. These can be adjusted for leveling purposes. Here is the pot supports with trivet in place and ready to go. The clearance from the top of the PuppyDawg silent cap to the bottom of the trivet is very good. It is also centered pretty well. This setup is quite stable, but if you are dealing with a klutz that is another story. I use to use a Coleman propane camp stove and these stand up wickedly high and tend to be unstable, but I never had any problems because I do my best to be careful. Preheating the burner. Burner up and running. I used an old 12 cup glass carafe for the boil test. This stove was never really intending for cooking or camping. It was used in WWII to sterilize dental tools. As can be seen this stove is no power house, but it did boil 12 cups of water in 15 minutes. Not bad for a small burner. The 527 is a small compact stove and if someone wanted to use this stove on a camping trip or backpacking it would work well. One would need to come up with some sort of wind shield. This stove will run for quite some time with a small amount of fuel. The fuel tank/fount is small and doesn't hold very much fuel. Due to the oval top of the carriage bolts some pot and pans may not sit quite right, so if you are having problems with this one could use on of these. I have both the 4.5 in and the 6 in of these wire mesh trivets. Of course this is just one solution for cooking with this stove and I'm sure someone will come up with something better. Such as pot supports and trivet that either fold up or at least break down easily for camping or backpacking. I hope this gives someone out there a better idea for cooking with this stove. Cheers, Norman
