Being a gear head is like being an immortal deity, in that there is always something else that needs to be done. Stitch up this, repair that with duct tape, or punish the wicked. The last is my favorite–just ask some of my former students.
That’s the stove being primed with alcohol, though not the drinkable kind.
I have added the windscreen to my Optimus 45, and it didn’t quite fit the brass flame spreader. I suspect these reproductions were made by different manufacturers in either India or China/Taiwan. Looking at photos of the original Swedish ones on the interwebs, I concluded that they were meant to friction fit into one unit. A bit of filing with a round file accomplished that purpose.
The number of add ons for this stove are staggering, down to and including rubber feet for the brass legs, which I will pass on. To keep your house from smelling of kerosene, the fuel tank has a reserve cap, which screws onto the end of the pump while the stove is in use–very clever. Put on the roarer burner, fill the round reservoir, aka spirit cup with alcohol, and slide the wind screen/flame spreader combo on top. It now fits perfectly. Then light the alcohol, and wait for the kerosene to gasify. After that, it’s time to cook.
A magnum opus is in the works by moi about how to work the various kerosene stoves properly. If it’s like some of my woodworking projects, it should be finished by the next decade, around 2030.
