I think this has been a wonderful thread. I would like to add that if anyone is interested I can supply them with a coil made of Titianium exactly as shown in one of the first pictures either in 3/8" or 1/2" outside diameter. The only drawback is you have to get your own fittings. The coil looks just like the picture shown (no ends). The price will be cheaper $210.00 plus shipping. If interested email me at rjn@jmzcomputer.com Thanks Rod Be sure to put Titanium coil in Topic in bold.
