Hi Bart 

With all that you will be spending on coiling, I believe that a propane torch 
at ~$18 is a great investment. One cylinder should last a year or more, even 
if you also use it for ===> making Plumbing Repairs. You can also get smaller 
butane soldering torches for about half that price from RS, but they may not 
have enough heat for a larger job. This is NOT the only time you will need to 
do soldering in your TCer life.
