I had no idea these were around until I read The Warrior's post on his 210 fettle: Primus 210 Fettle I thought the pilot looked really neat so I decided to make one. It's not too complicated, all you need are a small section of brass tubing (I suppose copper would work ok too), a 1/4" copper plumbing cap, a small piece of carbon felt, and a small brass strip or piece of wire to hold your pilot onto a burner tube. My starting materials, a 1/4" copper cap and about 3 inches of 7/32 bronze tube: I drilled a hole that was slightly larger than my tubing in the cap and flared the end of my tubing that would attach to the cap: I pulled the tubing through the cap, and soldered the flared end to the cap. Then I stuffed some carbon felt in the cap and crimped it shut a bit with some pliers and attached my brass strip formed into a clip: One the stove: And it works!!! Pretty cool little addition and all you need is rough plumbing soldering skills to make it, plus the materials are cheap and easy to get.
