REFLECTOR: nose gear air seal

[gibbons]

Hello
Chuck  Give me a call @661 256 8272. I can tell you a way of closing the
hole. It is simple. I'm  not good at writing it down.

Some time ago, someone posted that they put a boot on the retract nose
gear leg and anchored it to the slot opening that the nose gear strut
moves through.  Apparently quite effective.
 
I wonder if, even with John's silicone trick, the nose gear doors can
ever be sealed tight enough, consistently enough, to reduce air
intrusion into the nose area, by a meaningful amount.  
 
I cut down the air intrusion from the nose gear opening in the front
bulkhead that transited into the cabin through the opening in the top of
the keel by using a few pieces of soft foam stuffed in opening around
the wires and elevator push tube.  Cheap and the friction on the tube is
so small that's it imperceptible.  
 
Where the elevator tubes penetrate the side of the hull, I took the
plastic shower rod protectors that snap over a show curtain rod, cut off
a 1" piece which snaps over the aileron tube and slide it between the
tube and the fuselage sidewall.  The gap between the plastic tube
protector can then be caulked shut but the elevator tube will still move
inside the plastic sheath with near zero friction.  This only works with
the offset aileron tubes that rotate around the the tube axis and
doesn't move laterally.

Seal with silicone.  You can use silicone on the center joint between
the two doors and then cut them apart with a utility knife.  For all
other areas you need to protect one surface with saran wrap so you don't
seal your doors shut.

Hello everyone... 

I have an XLRG and get a lot of cold air (winter time) that comes up
through the nose gear opening. The nose gear doors don't form a good
seal and the opening near the gear's pivot axle is where all of the air
comes from. I was wondering if any of you have come up with a solution
to seal this area or at least reduce the air flow.
