For quite some time I’ve been machining adapters and reproduction parts for vintage stoves. I’ve been doing this on much of my client work as needed. I’ve always taken the if-it-could-be-done-before-it-can-be-done-again approach. As I’m getting a bit older, I thought now would be a good time to start recording some of the measured and *proven* threads or thread approximates I’ve come up with that will work well on vintage stoves.
But… first an important fact to understand. The various companies that made stoves (Optimus, Primus, Radius, even Coleman, etc) DID NOT necessarily conform to established “thread standards” for much of their work. This is especially true of the early standards established by Primus at the end of the 19th century (1890’s). Standardized threads would include the metric system, the British system or the American system. Some of these threads may appear on some stoves. But, for the most part, the threads used on vintage stoves are in-house creations of the production staff at the various firms and DID NOT conform to established standards.
Since Primus was the first to get stoves out there, and because they established a wide-spread international network of stove sellers and stove part houses (think todays franchises for fast food), other manufacturers were pretty much required to adapt their thread forms so that they could sell various parts that would mate with Primus stoves. Doing so meant that a Radius burner would fit perfectly on a Primus stove riser, for example.
So, yeah. I *know* that Sweden adopted the metric system in blah-blah year. Doesn’t matter. Stove threads pretty much ignore thread standards, and, that’s what makes stoving both fun and frustrating.
If you are a hobby machinist, you could make a bundle of money making up stove accessories and adapters for some of these old stoves. Sell them on eBay! I sincerely encourage you to do so. You’d be surprised what stove collectors will pay for a bit of brass properly threaded with compatible threads for their stove.
So, here’s the start of the list. I’ll add to it as I find time and energy. I have notebooks full of thread data. Check back whenever you like or if you need data for your stove restoration project.
Stay tuned for more as I find time. BD
Earlier this Fall season I posted a three-part video series on repairing the Optimus 111B at my YouTube stove channel. The videos cover all the steps you need to take to refurbish a vintage 111B stove back to full operation. There are tons of tricks and tips, and practical knowhow included in these videos which will help you working with the 111B, other members of the 111 family, and stove work in general. The videos are free to watch and require no admission or registration fees to watch them.
Check ’em out!

Is it possible to “heat and air clean” the carbon and other crud from a regulated burner using compressed air and a torch?
Hi Burner Guy
Thanks for your question! Yes! Absolutely, you can clean regulated burners using the manufacturer approved heat and air cleaning method. Like all burners, you’ll want to disassemble the burner, removing the jet, the spindle and the spindle nut.
But, you’ll need to close off the spindle opening.
So how to block the opening at the spindle? What I did was take a spare spindle nut and silver braze a cap on the open end. I just used a slip of brass sheet over the open end and machined it round after the brazing. But, you could leave it rough and all and it would still do the job.
Once threaded into the spindle housing, the modified spindle nut will direct the air through all parts of the burner and out the jet.
(PS – Before anyone asks… yes, this is a very odd burner and is somewhat rare. It was close to hand from a long-term stove project I’m working on. So, yeah, it looks a little different from your everyday standard regulated but the idea is still the same.)
I bought a Swedish Svea 123R factory brand new about four years ago. It’s always had a small candle flame at the jet whenever I turn off the spindle. Do you have any tips you can share about how to fix this? Thanks!
Bert in MO
Thanks for your question. One thing though…
Here’s the lowdown on candle flames on the SVEA 123R.
It should not have a ring worn into it and it should not have a step or steps worn into it. If it does, then someone has been closing the spindle valve too hard and has damaged the spindle tip. If there is enough material still there (if the damage isn’t too bad), you can chuck the spindle into some sort of spinning tool. A cordless or corded drill will do the trick. A drill press or a lathe is even better. Reshape the cone on the end of the spindle with a fine file and sandpaper while the spindle is spinning in your spinning tool of choice. If you can’t get it fixed because there is not enough material left or the damage is too great, you’ll need to replace the spindle.
Happy camping! BD

Do you have a stove that’s not on the list and want to know which cap to get? Just drop me an email at email@example.com You can order your custom BD caps at i.materialise (EU). My former USA printing partner got WAY too greedy and I’ve severed our relationship.
I was asked to make an adapter for the SIGG FireJet stove so that the stove could connect to a Primus Omnifuel Ergopump hose. You can see the full story at my YouTube page right here: https://youtu.be/MH9CWeeqfOs
I’ve also posted the full SIGG FireJet manual as a PDF here at my site (16.4MB). Click the highlighted words below to see it. Click the “Download” button below here (not the image) to download it to your computer.
