A Nifty Borde Pot Stand

I’ve had this little Borde stove for some time. But, it came without a pot stand. I put this pot stand together from stainless steel sheet. The sheet is 0.032″ thick. The legs are from stainless steel tube 1/4″ in diameter. The pot support rods are 5mm stainless steel rod. All the stainless is 304. I made 1/4″ long plugs of some of the rod which I TiG welded into the ends of the pot support legs. The 1/4″ tubing legs are silver brazed to the sheet sides. The stand forms a triangle about 5″ long per side.

After all the fabbing work was done, I gave the whole thing a polish up to make it look pretty. You can see the stand in use in a YouTube video at my BernieDawg Cinema channel: https://youtu.be/I_GQG8TbO_s

It works great and folds down small. A-OK by me. You can click on the images for bigger views. Maybe this will give you some ideas or inspire you to try to make something for your stoves. Gear-building is fun!

Primus 100 Silent Cap?

Dear BernieDawg
I found a great old Primus 100. It works well and is very nice. But, how can I make it more quiet for use in camp in the early morning ? Thank you for your help!
Hi Noisemaker
The Primus 100 stoves are among my favorites. A silent damper cap can make your stove quieter, and also generate a better fuel/air mix for efficient burning.
 Best choice is a Primus 4010 silent damper cap. They work super awesome on the 100s.
Base-Camp in England had some of the 4010’s a while back, but they’ve sold out of them now. Watch for a possible (though unlikely) return of the 4010 at Base-Camp sometime in the future, or ask around to some of the stove forums. Perhaps someone there would sell you one of their extras.
Another good choice for a Primus 100 silent damper cap is to fab up a cap adapter I call a spigot plate. I’ve made lots of these over the years. It’s a great newbie brazing project for anyone who wants to work on stoves.
Basically, you take a round piece of sheet metal with a hole in the center and braze a short piece of 5/8” diameter tubing to the middle.



The spigot plate holds the inner cap centered, and the outer cap settles around the inner cap.



You can make the diameter of the sheet metal base to fit either the first or the second ledge in the lipstick burner bell and then just use a regular cap set with the stove.



Good luck on this project. It can be done with hand tools and an electric drill. You don’t need specialized tools.
Happy camping!

Kolibri (Hummingbird) Stove – from Hungary

Here’s a Kolibri kerosene-burning stove I received from a seller in the stove’s native country of Hungary. Kolibri means “Hummingbird”. It’s an attractive little porcelainized stove with very 1950’s or early ’60’s styling.

Just click on any image for a larger picture.




Sadly, while I received two of the original inner caps, no outer cap came with the stove.

Here are some detail shots of the stoves workings.

The on-off valve is missing it’s plastic or bakelite handle. This valve does not control flow rate, only whether the fuel is on or off.


The knob on the front controls the cleaning needle which acts to throttle the stove.

10This ceramic knob pump knob is unlikely to be original. It is probably a cabinet door pull. The original would have been a round black sphere.11 12

The stove was disassembled and cleaned.

The unique shaped NRV (Non-Return Valve) from the bottom of the pump tube.

As the stove came without a complete set of silent caps, I made a pair of stainless steel outer silent caps to match the inners. The number and size of exit holes and the general shape and size of the outer caps I based on inspections of photos of complete stoves researched from the web.

The fabricated outer caps worked well. Strong full flame. Note in the photo below that I repaired the chipped porcelain around the pump tube mount with matching white epoxy paint, built up in layers and smooth and polished with ultra-fine abrasives and polish.

And a nice simmer.22

But, I also liked the performance of the stove with this 3D laser-printed BernieDawg prototype cap.



Silent Cap for 111B?

Hello BernieDawg,
I’m sure you’ve received this question before, but I’ll go ahead and ask. Do you have a silent damper for the Optimus 111 stove (hiker) with the “roarer” burner?
“Bugged by Noise”

Hi, “Bugged”
Thanks for your question and your interest in my silent cap products. I *have* received this question quite a few times.

The short answer to your question is no. No one anywhere to date has a silencing product to work on your 111 roarer burner. Sorry.
Now, in the past, some folks have gotten all mad and upset about this. It’s almost like they think I’m holding out on them or something. So, I hope you won’t mind too much if I try to show why I do not have any caps for the 111 style burner.
Here’s the explanation. The standard 111 or 111B burners have the traditional shaped design where the vaporization chamber is above the jet. Fuel moves into that chunk of metal above the jet (the burner “head” or vaporization chamber), the fuel is heated into a vapor up top and then the vapor moves down a tube, into the jet and spews upward as flame to heat the vapo chamber. It’s pretty neat how these work, really. These burners look like this one on a Optimus 22:
111 roarer copy
All silent caps, mine or others, are designed to work with another, and very different, type of roarer burner where the design uses a bell-shaped structure. Here’s a Dragonfly burner without it’s flame plate in place. With this burner, the jet spews vapor upward which hits a flame plate above the burner. The flame plate spreads the flame out and the flames heat the side walls of the bell. The heat from the flames is conducted back down to the base of the burner which is where the vaporization of the fuel is going on.
What the caps do is capture the vapor stream and emit it through hundreds of tiny holes. There are then hundreds of teeny flames that bathe the rim of the bell in heat and the heat is conducted back to the base of the burner to vaporize the fuel. Lots of teeny flames are much quieter than one big monster flame.
You can see how the flame plate sits on the bells of these two Primus 96 stoves.
This is a burner from a Phoebus 625 which really shows the bell structure well.
It is pretty straightforward to replace a flame plate with a silent cap on a bell-shaped burner. Just pop the flame plate off and add the cap to replace it. Here’s a MSR FireFly stove shown with a flame plate and then a silent cap.

But, so far, nobody has been able to come up with a way to remove the flame ring on a standard roarer burner with that overhead vaporization chamber and add some sort of device to make it silent.
111 burning
Believe me when I say I have thought long and hard on how to make a “cap” for the traditional overhead vapo chamber roarer. I’ve tried a few experiments, too. Nothing that’ll work so far. The feller who can come up with a way to silence these burners is going to have a really popular product on their hands. 😉
The good news is that Optimus made a silent version of your 111 stove in two different flavors, the 111T and the 111C. These came standard with a third type of burner which is designed to operate very quietly straight from the factory, no aftermarket caps needed.

111C (out of it’s case ‘cause I was working on it):
The 111T is much more common, but both stoves show up on eBay from time to time.
I hope this helps explain things. Good luck to you if you decide to pursue a 111T or C on eBay. They are really nice stoves – you wouldn’t go wrong if you bought one.
Happy Camping!

Coleman 345 (and 348!) paperwork

Hi BernieDawg
I’ve heard you have lots of documents in your collection. I have a Coleman 345 marine stove and I would really like to get the instructions for the operation of the stove. Do you have such a thing?
Coleman Searcher

Hi Coleman Searcher
You bet! I have the instructions for both the 345 (kerosene) and the 348 (denatured alcohol) versions of these awesome old marine stoves. Here is the paperwork for your stove:
(just click on the thumbnail images for the larger versions)
Coleman 345 pp
Coleman 345-2pp

I don’t believe that these sorts of documents on old stoves should be kept behind membership requirements or pay-to-view mechanisms on the internet just to promote the sites that hold them hostage. I believe that the free exchange of information without strings attached is what best promotes the collection and preservation of old stoves. Isn’t that what the internet is supposed to be about?

I hope this helps you with your stove. It’s a nice one!

Happy camping!

UPDATE! Here are the instructions for the Coleman 348 alcohol burning version of this marine stove set.

A “Tool” for Burner Removal – Optimus 8

With some vintage Optimus 8 stoves, there is no nut cast into the fuel feed pipe.



This makes disassembly to service the wick or unclog a fouled fuel line difficult. It is quite possible to break the fuel feed/vaporizer by trying to remove it through applying force to the spindle housing or the the small “stilt” that supports the burner. Then your stove is toast!


Here’s a simple do-it-yourself tool you can make. To remove the fuel feed/vaporizer body from the tank, make a block of wood. Drill a hole through it just the size of the fuel feed tube.


Then, cut it in half lengthwise. A thin-bladed saw such as a bandsaw works well for this so that you remove the least material. You could also use a Japanese pull saw if you don’t have machinery.


Clamp the block around the fuel feed tube in your bench vise or with a big clamp. Turn the tank counter-clockwise by hand to unscrew the vaporizer from the tank.


You can then service a clogged or charred wick, replace the wick or what have you. Enjoy the blue flames from your service work.



BernieDawg Cap Instructions

Hi Berniedawg
Where can I find instructions on how to fit/mount your silent caps on various burners, say like the Svea 123R? Youtube maybe?

Hi “Hans”

Thanks for your BernieDawg cap question.

The instructions for the caps can be found at:

That same link to the instructions can also be found at the main page of each of my product manufacturing pages. (it’s down at the bottom of the text.)

The link can also be found at the end of the description of each cap product at my manufacturers, Shapeways and i.materialise. When you decide to order a silent damper cap product, you can just cut and paste the link into your browser to get to the instructions webpage.

Happy camping!

Making a New Pump Tube

A Burmos 96 stove was sent to me for removal of a badly stuck NRV. After replacement of the NRV there was still leaking going on in the pump tube. I removed the pump while the stove was pressured and added some water in the pump tube. Using a small but strong flashlight, it could be seen there were several locations emitting streams of bubbles around the inside of the pump tube. This was likely caused by poorly drawn brass tubing that left stresses in the tubing back when the stove was made.

The pump tube was pulled and the tube was replaced with one I manufactured to match here in the BD Labs. Those photos follow.

Optimus 11

This is a late-in-the-series Optimus 11. This stove has never been fueled or fired. The spindle knob is not original to the stove. The knob form on the spindle is correct for the period, but the shaft is a round end that I consider mechanically squaring so that it could be used with the square spindle on the stove.
