It does seem a How To Guide for building your own burner is open for discussion so let me start with my version.
Grab a length of 3/4" copper tube about 6"s long and close one end in a vice and hard solder it. Now wait until it cools until we do the suck test, going too soon will end up with a sore mouth
Now when the suck is done and proven time to move to the end and hard solder in a 1/4" BSP nipple and again wait for the suck test. Once this id done and proven get a 0.7mm drill bit a bit over an inch from the closed end as we want to hard solder on a 2" pipe that we can trim to get the air/gas ratio right. Now a 1/8" copper pipe needs to be around the hole and remember the higher that 1/8" is the more trimming but it must be atleast 3/8" high so the flame can start. use a dremmel cutter to trim and remember that bit too much will cause balling which means we went too far. So if that happens just cut off the 2: and hard solder it on again and keep trimming as we do need to get this right.The ones i make work nicely on 3-5 psi and yes they will go up to 50 psi and put out some serious heat and noise too, I reckon mine on 5 psi works on about 45-50DB and when I trough it right it is hard to hear the radio and the surrounding area is pretty warm too.
I find off a 8.5 Kg bottle I will get 3 runs using a 50 litre boiler so I'm happy with that.
Let the discussion begin
