Vince,

I cut two pieces of low density polyethylene about 2.0" wide and 5.0" long.  I
lay one on top of the other then fold it in half and push it down over the tap
clip.  The adjacent primary windings hold it in place.  This is one reason that
I make my primaries with 3/8" spacing between adjacent turns.  Leaves about
1/4" clearance after the tap is in place and the ldpe helps as well.
