Hey Bob, Mike,
Yeah, see what it takes to get 2mH using pales. Need two, maybe more.
That's why suggest to use the bigger former at 18-22 inches, providing
it will fit in whatever box will house it. They are also available from
the home stores.
With the larger form, the resulting coil should have a better Q as the
L:D ratio will be lower and more optimal. One program has the ideal as
.45 : 1.0.
My initial attraction to the 5-gal pales was they were common and
cheap. I made one and it didn't give the needed L. I didn't want to use
a smaller wire so I had to look at a larger form. Ha, still lookin.
Cheers, Peter

Mike: I wound two buckets with #14. Each had about a 10" winding
surface
and about 10" dia. With the two tightly coupled, I got about 2mh.
