Hi Patrick, Coilers,

I've had good success with hardwood end plugs for my secondaries.
The wood I used was two inch thick cherry, but you could use any
good DRY hardwood with equal success.  I don't glue or screw them
in place, but rather I just turn them on the lathe until they're
a nice snug fit in the PVC secondary form.

At to the height or unwound area of the secondary form above the
topmost winding, I generally leave about two inches.  The final
turn is an stretched out spiral and about a half inch down from
the end of the form I drill a very small hole diagonally up thru
the form and end plug so that the wire can be secured to the top
of the plug for attachment to the toroid topload.
