Here’s a list of stove part suppliers that I’ve used or know about. As I think on it, I may add more, so check back frequently. This list is current as of June 2019. These suppliers tend to come and go in many cases. If I’ve listed your outfit and you don’t want to be listed just let me know in an email. If you find a dead link or if you know of a link I should add, please let me know by emailing: firstname.lastname@example.org and I’ll try to add, update or remove it as required as soon as possible. Thanks!
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

Here’s the US Military manual for the folks who are digging these old military stoves. Big thanks to a happy BernieDawg cap purchaser who was kind enough to share this file with me, and with permission, the world! BD
Here’s a stove I imported from Europe. It came in its original packaging. I include some photos of the packaging for those who are interested in packaging history. I reckon this stove was made somewhere in the 1940-1955 range? Click on any image for a bigger view of that image. Please don’t steal images.
The Campus 5 came in two flavors a model with a pump and a self-pressurizing model. This would be one of the pump-equipped models, the 5. I believe the self-pressurizing models were termed the “5B” and usually had a tank-mounted SRV (safety release valve”, absent on this 5. The stove came equipped with an attractive spirit tin, a spindle control knob, a yellow rag/cloth and a pot stand.
The pot stand rests cleverly on the edge of the sheet metal case.
The stove shipped overseas complete with an unknown variety of fuels liquid which had leaked out over some of the stove.
A bit of cleanup and a flush of the tank interior, and things were much better.
The Campus 5 is a multi-fueled stove, meaning it can burn kerosene or white gas (aka naphtha or Coleman fuel). Below the stove is burning white gas on a first fire. There are lots of streaks to the flame caused by debris escaping from the tank and burner after a long period of inactivity.
I have a short question about the bernie dawg silencer caps. Does the Omnifuel Cap fit to the Multifuel Burner?Best regards,Stove Guy
Both stoves, the Varifuel 3278 and the Multifuel 3288 work well with the Minicap, either with or without legs. I recommend the Minicap with Legs if you are only planning on using the Minicap with one of these Primus stoves. If you would like the flexibility to use your Minicap on other small self-pressurizing stoves like the Optumus 80, Radius 42, or Svea 123/123R, then I recommend the Minicap without Legs.
I have this great old Primus 100 stove that I’m trying to fettle. I’ve got the NRV loosened up, but it seems to be stuck in the bottom of the pump tube and won’t drop out of the tube. It’s hung up somehow. It wiggles around and is loose down there at the bottom of the pump tube. I wonder if there’s some gunk in the tank that’s hanging it up?
What can I do to get it free?
Stuck and perplexed
a. there can be a little burr of brass where the vent hole in the side of the NRV barrel was punched in the barrel. You can use your alligator forceps gripping the NRV head with an unscrewing motion (like you are unthreading the NRV) to “unscrew” the burr past the opening in the pump tube end plate. Do it with the pump tube opening facing toward the floor to allow gravity to assist you. Use a little 400 grit wet dry sandpaper or a small file to remove the burr once you’ve got it out so it doesn’t give you problems again.
b. the other problem comes about from using lead NRV head washers. The lead will expand outward when the NRV head is tightened down, sometimes into the opening for the NRV head threads. This can hang up the NRV. Alligator forceps should help you to get it out, again with that unscrewing motion. Consider to switching to HDPE (#2 plastic) NRV head washers. You can punch them from the lids of food containers, so they are cheap to make and they almost never cause these hang-up problems. They last forever, too.
Here’s a Svea 175 that I restored. It’s a great old marine stove that came jetted for alcohol but which I converted to kerosene. The stove appears in an old 1958 Svea catalog. The marine trivets seem to be a special option. Gotta love those excellent Svea #1915 regulated burners.
These slide out cups deliver the correct amount of preheating alcohol to the spirit cups under the burners via a long metal tube. The curved end inside the slide out cups automatically siphons the alcohol when the slide out cups are filled. Pretty slick!
The galvanized steel trivets were pretty well oxidized. I chose to gently glass bead blast the oxidation, but not the plating, off of the trivets. The one on the left is finished, the one on the right yet to go.
The cork fuel gauge floats on both of the tanks was perished. I turned new floats on the lathe from old wine corks.
Here is an Optimus 111T that I “restored” for a client a few years ago. The client specifically requested the polished copper windshield and floor pan.
The embossed case was stripped, derusted, and repainted. The left hinge on the case was separated – the spot weld had failed. I silver brazed the hinge back in place before prepping and repainting.
Here are the beauty shots.
Sadly… the client was better at buying old stoves than actually operating them. Within three months of this restore the inept client had set the stove on fire, destroyed the paint, and melted part of the copper windshield surround. Sigh. :-(((
I often am asked to help out when a stove collector has problems removing a NRV (non-return valve) from the bottom of a stove’s pump tube. Usually the stove owner has done their best to remove the NRV, but has inadvertently rounded the soft brass head of the NRV valve. Sometimes I can get these damaged NRVs broken loose by using an “easy-out” (screw extractor bit) mounted in the end of a spade bit extension. I’ve actually made my extension a bit longer by welding an additional section of 1/4″ hex rod to the unit.
Sadly, this wasn’t possible on this old Monitor stove I was asked to repair.
I use the stove’s original pump lid, some washers, a bolt and a nut to make up this little pump pulling tool. It’s easy to do and works great without the fuss or expense of a “special” tool.
Usually I clamp the head of the bolt “tool” in my bench vise, hold the tank with one hand, and use the torch in the other hand to heat the area of the tank immediately around the pump tube. I put a wad of wet paper toweling all the way into the bottom of the pump tube to keep the heat from melting the solder holding the pump tube base block in place.
Here I’ve pulled the tube. But, I encountered some resistance as the tube would not completely exit the pump tube opening in the tank. It’s hanging up on the over-large pump tube base block.
It turns out that the folks that made Monitor stoves in England decided it was a “good” idea (not!) to make their pump tube end block larger in diameter than the outside diameter of the pump tube. There is no way to pull the tube while the end block is in place since its outer diameter is bigger than the hole the tube mounts in, so I had to desolder the pump tube end block from the pump tube and have it drop into the tank.
You can see in the photo above that that too-big end block is not going to fit out through that too-small hole. But, by using a small pair of Vise-Grip pliers to hold the end block, I was able to machine two facets into the block to reduce its diameter. I used a grinding wheel on a Dremel tool to do the work, taking off just enough to get the block out the opening. I also made sure I placed the facets in such a way that I could later clamp the block up in the three-jaw chuck of my mini-lathe to clean up the block.
Once the outer diameter of the end block is machined down in a couple of places, it pops right out. A little persuasion with some penetrant and some torch heat pops the NRV head loose from the block.
This stubborn NRV had a lead washer in place under the head. Didn’t seem to do much good to assist in removal, though. This is often the case with old lead washers as they seem to tend to get brittle and harder with age.
Because I had to desolder the end block inside the tank and with little control to the operation, the lead washer “migrated” a bit into the block and also into the threads of the block. I chose to clean the lead residues out of the block as I didn’t want this old lead to be causing me problems later on when resoldering the assembly together (I wanted to avoid contamination of the new solder with the lead). Spinning up the block on the lathe took care of the inside of the block and using a tap cleaned up the threads nicely without removing any brass. I’ve found through doing many pump tube pulls in the past that a 5/16″x36tpi tap is a remarkably close and completely functional match for the original proprietary non-standard NRV head threads.
So… I then soldered the end block back into the pump tube, then turned the pump tube end block flush with the pump tube diameter so that I could get the assembly (easily and sensibly) back inside the stove tank.
I needed to cut a special small pip for the small-size “tailed” Monitor pip cup.
I also chose to rebuild the head of the Monitor NRV since it was slightly different than a standard NRV in an effort to keep things sorta “original” looking.
First step was to machine off the twisted remnants of the NRV head.
Then I cut a socket or “mortise” into the head of the Monitor NRV head.
Next was to machine a small piece I could silver braze to the NRV head to restore the NRV head. I made a corresponding “tenon” to fit the “mortise” I’d cut in the original Monitor NRV head.
I cleaned up the brazed head, then hand-filed the two facets in the head.
Here is the completed restored pump tube and rebuilt NRV ready for reinstallation into the Monitor stove tank. Note my use of a shop-cut HDPE (high density polyethylene) plastic washer in lieu of a lead washer. I’ve found these HDPE washers to be entirely fuel resistant and superior to lead washers. The HDPE does not stick to the brass of the tube or creep into the threads of the pump tube end block. It also provides a fuel tight seal with much less torque required to make the seal than with lead washers.
Here I’ve used my simple bolt-and-washer tool to set up the pump tube in the tank for soldering, holding it in place with some stiff wire jigging. This jigging setup allows me to use both hands – one for using the torch and one for applying solder to the pump tube/tank joint.
I use standard electrical solder and rosin paste flux to do stove soldering. The rosin flux is inert until heated and any flux residues trapped inside the joint will not erode the brass of the tank on down the road. Acid fluxes will erode the brass over time which is why acid fluxes should never, ever be used around vintage brass stove work.
Inspecting the completed joint. I’m looking for any gaps or pits where solder may not have flowed into the joint. There should be a uniform silvery and liquid-looking seam of solder flowed in all round the joint.
The owner of this stove is a competent stove collector who may or may not chose to polish the stove. I’ll leave that chore to them. I hope this overlong treatise maybe helped some readers who were considering repairing their own stoves.
These surplus Swiss Army two-burner gasoline stoves turn up on the popular auction sites from time to time.
You can watch a three-minute video of the one I have on it’s virgin burn one cold January night. The video was shot about four years ago and you can find it at my YouTube channel, BernieDawg Cinema, right here:
