Re: copper plating

a great idea,,lets experiment further with this, the reason is that ive had
an idea about making torroids out of fiberglass, you can form it into many
different shapes and sizes , then sand it smooth and plate it with copper or
even chrome it.they would hopefully be a huge improvement from ducting for
torroids..the only thing would be the capacitance of it since it would be
non metallic inside but metallic outside...but a perfectly shaped 8 by 24
inch polished copper torroid would sure be impressive...
