[TCML] first coil help

[bartb]

Actually, hit the hardware store. Precut tubing 1.25" in diameter about 
3" long. Nice edge, perfect, and ready to go (no cutting required). I 
also would use pipes rather than bolts simply due to better thermal 
dissipation. But Scott is correct that 2 bolt types can work ok (not 
wonderful, but ok). Your better off however with something in the 
neighborhood of 1" diameter pipes with a good fan (my opinion).

Take care,
Bart
