Thanks for the kind words. Honestly, most of the cool ideas are not mine. I think the only thing I came up with (and I am sure someone did it before me) was the dual coil arrangement. Otherwise it is just creative application of other ideas.

As with anything I build, I keep detailed spreadsheets for everything. If anyone wants my workbook, just PM me your email address and I will send it over.
That wire ducting just makes these installs so slick and pro-looking! I love it.
