The great things about decades old designs are that they work consistently, last forever, and acquire all manner of add ons. This seventies vintage Optimus 45 kerosene stove has any number of improvements and additions. I will go from the most complex to the simplest.
Cobra Burner
The Cobra Burner, aka the Silent Burner, was originally made for the Optimus 48 stove. It didn’t take long before campers found out it also fit the 45. Though no longer made in Sweden, these burners are widely available, as they are made in at least two south Asian countries, where these wonderful stoves are often the main cooking utensils used. Allegedly, they are widely used in Himalayan base camps–by the guides. I bought my parts from Julian Shaw in the UK, via fleaBay. He knows his stuff.
This was my first choice for a Christmas present. It turned out the complete assembly was comprised of eight parts, with no instructions for assembly. I suspect this burner was made in India, which is the primary source of reproduction stoves of this variety (the other is Malaysia). There are also very high quality versions of this stove made in Japan, at an also very high quality price.
After some research, I assembled the burner in the proper sequence. The jet was clogged, and needed a thorough cleaning to even operate. Then it still roared, though less than the original burner. On the sixth trial run, the magic happened–it began burning “silently,” which is actually a very quiet hissing sound.
After a few minutes of observation, I came up with what the American philosopher Charles Sanders Pierce called an “abduction,” which was his term for the process that is used to create a hypothesis: The sound and heat level was determined by the amount of pressure in the stove tank. I tested it again, and was proven to be correct, as all it took was more pumping with the pump on the right side of the stove, to produce the classic blue flame.
Heater Dome
This simple device fits any stove with a ring, regardless of manufacturer, and produces prodigious amounts of heat. There are pictures on the internet of these glowing red. After reading Into the Wild, I am never going to use this inside a tent, which was its original purpose. It will make a great hand warmer in the outdoor kitchen during the winter.
Flame Spreader
I also upgraded the old Roarer Burner with a flame spreader. It really helps to intensify the heat from the original burner.
This flame spreader just sits on the top ledge of the burner. The next addition is a companion brass windscreen.
My wife Melanie Jane thinks this thing looks like a baby Dalek, after the alien villains in the BBC show Doctor Who. However, to paraphrase Gertrude Stein, a gear head is a gear head, is a gear head, is a gear head.
