Use standard 1/4-20 nylon fasteners x 1 inch long.  4-8 pcs.  Drill 
and tap a pice of 3/4 inch plywood endcap fitting flush into the end 
of the tube. Drill with a #7 drill, then tap with a 1/4-20 NC tap 
being careful not to overtorque the tap and damage the threads.  Back 
the tap out and thread in the nylon fastener.  Use either 4 for a 
small coil or 8 fasteners for a larger coil.  Easy, fast, and cheap.

Nylon & fiberglass fasteners from McMaster-Carr, Chicago (check them 
out online & request their excellent catalog).

Sec is attached to base with a standard 1/4-20 brass rod or 1/2-13 
brass rod for larger coils.  Interior is covered with generous amount 
of GE Silicone II (Home Depot or hardware store) --- be sure to use 
the clear not the black version.
