Found this stove on the local Craigslist. Was particularly pleased because it was one of the stoves on my wish list, and did not expect to find it here in Portland, Oregon. Of course every stove leads to a question, but first some pictures. Here is the stove as found... And the box... After replacing cap gasket and tank gasket, was able to get the stove fired up... Started to clean the silent burner cap... And was surprised to see it was marked, "Made in Sweden, Radius K"! So the question is, was this a replacement for the original? Or were these supplied with the stove? The bottom of the stove tank is marked "P", 1926. Don
Hi, the Primus No. 100 is basically a stove fitted with a "lipstick" shaped vaporiser and a bell-shaped burner and a separate flame-plate. An optional extra was a silent "Damper", which replaced the flame-plate and allowed the stove to operate in "silent" mode: https://classiccampstoves.com/threads/primus-100-4043-1961.5879/ You do not have a silent damper with you stove. What you do have is the inner and outer burner caps of a conventional slient burner, such as is fitted to a No.5 type stove. Unfortunately, this arrangement will not work with the lipstick vaporiser/ bell shaped burner of your stove. Best Regards, Kerophile
Hi @taku, these Primus No.100 silent dampers are difficult to find now. If you wish to run your Primus No.100 with a conventional silent burner, which are readily available, you an buy an alternative riser tube, which will allow you to connect your tank to said silent burner. Have a look at this thread: https://classiccampstoves.com/threads/1926-primus-no-100.28153/ What is the date code on the bottom of the fuel tank of your stove? Best Regards, Kerophile.
Hi, thanks Tony @Tony Press Well there is a coincidence, the link I provided is also of a 1926 stove, so the adaptor riser I described will fit the female socket in the top of your tank. Isn't it great that these 90 year old stoves are stll operating as intended after all these years! Best Regards, Kerophile
The riser sounds like a good solution. I also need to track down a travel cap (No! Not again!), so it looks like an order is in my near future. Here is the stove after a little further cleaning. I decided not to polish the tank because the original lacquer is still doing its job, and the stove looks fine as it is. BTW. When I first started working on the stove the burner was stuck to the tube. My first instinct was to grab a hammer and start making two pieces out of one. I looked at some of the solutions on this site for 96 stoves, but then remembered that after market silent caps would lock into the bell if left to cool (because of the different expansion coefficients). Reversing that process, fired up the stove for the first time - letting it run for the better part of an hour - turned it off and immediately slipped a rod through the slots in the burner, tapped the rod with a small hammer, and voila! Off it came! For once, a non-destructive solution! Don
Taku you might be able to make your silent burner work. Read this post https://classiccampstoves.com/threads/gaz-bleu-pétrole.32452/ You will need a scrap fount to make a drop down pipe and a brass washer.
Hi, I bought the adaptor riser for my No.100 stove from a small business called Parafinalia, who have always provided a great service and the part is very cheap at less than £2 GBP. HOWEVER they have the worst designed web-site I have ever tried to navigate. http://www.parafinalia.biz/generic-spares-for-pressure-stoves-752-p.asp Look for "Which spare...Choose from here. The part you need is the No100 socket stem Best Regards, Kerophile.
