Walter,

Sounds like you're already  much more expert at this than I but I'll tell
you how I'm doing it anyway.  I got two ports from Aircraft Spruce - used
the ones that are about $17.00 each - turned aluminum.  I removed a 1 5/8"
circle of inner graphite and honeycomb 4 inches behind the bulkhead that the
Hydraulic pack attaches to and about 3/4" below the joint for the upper
fuselage.  Did this on both sides.  Mark Mahnke at Lancair confirmed the
position.  The aluminum ports are designed to be surface mounted on the
outside surface, but I  bonded them on the inside - potted them with
superglue in the holes I made, then filled around them with epoxy/micro and
covered with two BID.  Next I used a #50 drill to pilot through the hole in
the aluminum ports and through the fuselage right and left side.   I'll put
a decal around the holes to keep folks from painting over or plugging them.
They'll be totally flush and will present no drag.

Per  Mark Kirschner and others, I then routed the tube via 1/4" plastic
elbows such that it first heads up and forward at about a 45 degree angle to
horizontal and then attaches to a second elbow which routs it downwards
again as it passes through the bulkhead mentioned above.  Then the flexible
tubing will rest in the depression along the side of the fuselage at the
outboard edge of the elephant butt (wheel well cover) on its way forward to
the instrument panel.  The purpose of this routing is to ensure that
moisture from rain and other precip can not pool in the static line and then
freeze thereby plugging it up.

Regards,
John Barrett
