I bought an early Monitor Hi speed picnic tank at Newark a few days ago. Although I had a spare burner bell and plate I had no lipstick to go with it. I have been making lipstick burners for many years now, and after breaking dozens of small drill bits, I am now convinced that the most reliable method to make lipsticks is by brazing a thick cap on the top to take a conventional nipple, rather than brazing on a thin cap and trying to drill a 0.32mm hole. I and others have documented details on how to make lipsticks before (for example here), but below is a pictorial guide showing how I made this one. About a 40mm length of thick walled 13mm OD tube was brazed onto a 16mm x 1.25 pitch short hollow bolt. NOTE: The actual length of tube depends (amongst other things) on the individual stove pot leg height, and needs to be calculated in advance in order to get the correct flame stand off from the bottom of any cooking pot. 3 mm brass plate for the cap, cut from sheet 4mm hole Threaded with a 4.5 x 0.5mm tap to take a conventional nipple Remove the nipple before brazing the cap in place, and then roughly round the cap with a file/linisher. When the lipstick cap is round, taper the top 15-20mm of the lipstick by mounting the bottom of the lipstick into an electric hand drill, and then feed the rotating lipstick onto a linishing belt at a low angle (3-5 degrees) Keep checking to make a tight fit into the burner bell collar with the nipple just protruding into the burner bell. Now to make a cabinet for the stove!
@Twoberth Quick work, and great result! The removable nipple certainly makes servicing easy, and as it's screwd into a brass piece, no issues with loosening due to dissimilar metals... great stuff!
Thanks everyone. Another benefit of the nipple is that it can be removed and a 4mm dowel can be used to push out the gauze for cleaning.
