After the favorable results I obtained by sealing the gap between the horizontal stabilizers and the boom I wanted to make something more permanent than the duct tape I used for testing.I shaped a strip of styrofoam to fit nicely in the gap then used duct tape to protect the HS and the tube (duct tape is a great mold release). I used the poor man's vacuum bagging technique to prepare three pieces of BID fiberglass, peeled off the top layer of plastic and used the bottom layer of plastic to hold the wet glass as I molded it on to the plane. Once the plastic was peeled off it was replaced by piece of polyester cloth as a peel ply and paper towels as a bleeder ply to soak up any excess resin. This morning I pulled off the peel ply and gradually worked the seal loose from the duct tape.
After I make two more, I'll mount the top and bottom seals on the boom and glass around the forward end to bond them into a single seal.

Rick G/Folks:
I'm sure you are aware of this, but will make a friendly reminder just in
case. Unless the rudder hinge line is positioned exactly, it will have fore
and aft movement of one or both horizontal stabilizers.
What were the results of installing the tail boom/horizontal stabilizer gap
seals.

John- Please clarify the fore and aft movement. I was under the impression that the Mark III horizontal stabilizer was designed to move, for unknown design reasons. Also, unless Rick has something not shown in the photos, the tail won't fold.

Getting old isn't an excuse for mistakes. The above should have read:
"Unless the ELEVATOR HINGE LINE is positioned exactly centered, it will have
fore and aft movement of one or both horizontal stabilizers."
I have one pretty close that does not move, and the other a little out that
moves fore and aft 1/4".
Sorry for the confusion.

John, The elevator hinge line is positioned in line with the hinge bolt in the boom tube ring fitting and shimmed to stay that way so there is no movement of the stabilizer when the elevator is moved.William, There are two options for folding. Remove the seal, fold as usual, or slit the top seal so that the two pieces align when the HS is folded out and seal with vinyl tape.
