I was following coiling avidly for several years, with the intent of
building my own, up until about 2 years ago, I just recently reentered the
fray, so to speak. The one thing I would advise you to update yourself on
is the advancements made in capacitors. The development of the MMC
(multiple mini capacitors) has made the rolled poly and oil caps obsolete.
I personally think they are messy, a bear to build, and much more
expensive, anyway. Also, for software, I was recommended WinTesla that you
can find at
Good luck. I'm glad to see I'm not alone in getting back into coiling.
Everyone here has been extremely nice and helpful!
