 Steve,
 
 Looking at the photo, it looks like you did not drill the hole through
 the stick.  The part that fits the bushing hole should also penetrate
 the stick.  This will make it impossible to rotate or pull off the
 stick grip from the stick.  I followed some others idea to drill the
 hole about 15 degrees rotated inboard to make the stick grip fit the
 hand position better.  If you hold your hand relaxed as it would be
 resting on the grip, you should notice that your fingers are angled in
 slightly. Photos upon request.  I would have to search through my
 archive to find them.
 
 I would like to add that cutting a slot in the top of the tubing of the
 stick will help with routing the wiring down and out the grip.  Make
 the slot in the stick to match the location of the slot in the
 spacer/bushing.
