Just a note: My primary is made with 1/2" CU tubing and it is very difficult
to work with. I think quite a few guys have fired at  10 kW levels using
1/4" without problems.

Just a quick question . . .

Just finished my 10" x 45" secondary coil and need to create my primary.

Right now I'd like to size my primary for current duty (up to 5kW) but also
for the future up to 10kW power.

Some people told me 1/4" was fine, but I think this is too small?  What do
you think?  1/4, 3/8 or 1/2"  or bigger????

Thanks
Dan
