Re: tapered secondary form?
Tristan,
You definitely do not want any metal inside your coil. I don't recall
the size of your buckets, but what worked for me was hot melt glue. I
put together a 6.5 inch secondary using plastic paint buckets (1
gallon). They are utra thin polyurethane, so I figured it be good for
low RF loss. I ground off the handle catches with a dremel, then used
the hot glue in between each of the five buckets, as glue oozed out, I
scraped it with wide blade screwdriver (while it was still hot). This
held very well, and I haven't had any problems with coil!
Hope this helps!
P.S. (for you coilers with tight budgets, this is a cheap, quick form
for secondary - you can get them free from a painter or for a couple
bucks new.)
