Re: [TCML] primary voltage



PITA=pain in the arse. That's unfortunate they don't sell it in 50' lengths. It might be worth splicing if you have the tools or just buying online. For the 40' of wire you talked about they are going to wind it on an octagonal form about a foot in diameter. It's close to round but not quite and the tubing sort of falls into place if you do it right.

PITA? They carry 1/4" tubing, just not in the 50' length that I need. I talked with home depot, and they don't even have it in their warehouses. I fear the have discontinued it... Glad to see I'm not the only one using an iPhone for the list!

Hi Brandon, take it or leave it but I can assure you that any $$ savings by going with the wire will be offset by the PITA that is working with solid heavy gauge wire. Also I find it very hard to believe that lowes doesn't carry 1/4" copper tubing in your area. Those places are huge don't be afraid to ask someone where it is.

Good luck

You would need to have 40' of #6 ground wire to achieve the same values as 50' of 1/4" refrigeration tubing. And besides all that, I can't get any of that tubing from any home depot or lowes in Arizona...

I'm not sure that solid #6 wire is any cheaper than 1/4" refrigeration tubing (could be wrong tho), but it will be a lot more difficult to work with.

Bigger the coil bigger the primary and wire dia employed.


Based on what you've said here, and what I've been told by DC, Its not necessary to have a 0.25" copper tube primary for a fairly small coil (15kV 30mA, 3.5" Sec) to perform optimally, correct? From what I've heard from DC, 6 AWG bare ground wire will do the trick. Sorry to but
into the post with my pesky questions.

Thanks everyone!
