I need help with my static system.

I have had constant problems with water entering my static line and causing
my altitude to bounce all over the place. This happens sometimes when I get
into clounds and almost all the time when in precipitation.

My "solution" to date has been to install a "T" in the static line that I
can reach under the panel - I unscrew the nut cap and my static source is
inside the cabin.  That stops the altimeter from making it's 500' bounces,
but makes instrument landings a bit of a concern, because I end up with a
significantly less accurate altitude (a couple hundred feet at cruise, less
as airspeeds decrease).

My thought was to put another (alternate?) static port on the pilot side of
the plane (current port is copilot side).  Could folks out there please
recommend the best location for this static port (detailed measurements
would be much appreciated)?  I don't have my manuals handy now, and I want
to get it right this time.  I intend to route the tubing about 20 degrees up
from horizontal as soon as it comes out of the little epoxied in static
port... does that sound like enough of an angle (my copilot side port routes
the line up about 5 degrees - and I think I am still getting water in the
line (though I never "see" any after fact when I check the line).

Though I am dreading cutting up my interior, I need to improve my current
situation - I don't think it is a safe way to continue flying IFR.

Thank you in advance... (and please copy me directly at
matt.hapgood@alumni.duke.edu, as sometimes I get the list emails much
later).
