- Hi Mike,I will try and answer your questions later today or tomorrow. The sun is shinning here in Old South Wales and there are 15 yards of dual gauge track along with 5 points to be laid on the local model clubs garden railway.Regards Tony.From: mike.recycle <mike.recycle@...>

Subject: [pop-pop-steamboats] Tony - meths lamps, wick tubes, Parasene torchesHi Tony, thanks, your comments do help! I have a few questions:
> . . . . Use very thin tubes to make the burners and transfer pipes (K&S tubing) . . . .I wondered about thin tubes, and wondered if I could roll the wick tubes out of alu beer can, soldered with Techno-Weld (may be impossible), with thin alu pipes and tank too.
What is K & S tubing, where would I get it?
> . . . . have a baffel between the burners and tank to reduce the effcts of radiant heat. . . .Sounds good.
> . . . . A good way of reducing the heat transfer from burner to tanks is to use a short length of silicon tube in the supply tube, unfortunatley if you have a fire it will melt and add yet more meths to the conflagration, I wonder why I know that?Yes, it adds a risk!
> There is another mail regarding screw-on gas torches, I have use one for may years and have had small leaks which have been down to the disposable gas cans rather than the torch. The torch I have has a disadvantage that when the gas can is full the torch cannot be used even at a slight angle downwards as liquid gas will come out, this problem gradually impoves as the gas is used up. Most of the soldering done is by a torch with a flexible hose connection to the tank.The leak I had was very small, but gave a horrible smell in the workshop, and was dangerous of course.
Can I use the same torch head with a tube and tank, or is the connection different?
