See if you can get another horizontal. It isn't worth the time and effort
to save the one you have.

Over the couple weeks I've finished the installation of the EDM 800, 4 new
cylinders, installed the baffles for the new cowling, replaced all the hoses,
installed a new ELT, installed two comm antennas in the dorsil fin (onto the
channel, the dorsil fin itself isn't done yet), pulled the nose strut for
painting, sandblasted a bunch of parts for the powdercoater, and made the doublers
to
cover the holes in the turtle deck that were drilled in ordered to install
external comm antennas.
Each of the come antennas (the location of) had 20 holes. That's 40 holes
drilled in the fuselage to mount two antennas.
When I flew the plane to Lancaster, I thought the elevator trim was a bit
stiff. Not too unusual. Usually poor maintenance. When I started to take
the tail cone off, however, it became clear that no maintenance had been done in
the aft section since the plane was painted in 1997. I got the tail cone
off, replaced the tail light with a combination tail light strobe, and started
to disassemble the trim mechanism. Then,
I leaned on the rudder and it, too, felt very stiff. Lots of drag on the
rudder. I removed the rudder springs and tried it again. Still very stiff.
I had previously noted that the rudder busings had been replaced. Part of
the upgrades includes installing a flush rudder cap and removing the VOR
antennas. So, time to replace the rudder bearings. Upon disassembly, I found
the
upper spacer installed upside down. This causes a crush on the bearing.
Fixed that. ... now, back to the elevator trim.
One of the bolts holding the elevator to the control horn was crowded out so
I chose to ream it to 5/16 and install an new bolt. Well, that little
exersize revealed that not only was the rudder installed wrong after the painting,
so was the elevator. None of the spacer washers were installed to properly
space the elevator on the stabilizer. The space between the horizontal and the
elevator tip was 1/2 inch on one side and 7/16 inch on the other. Max is
supposed to be 0.35 inches. Now, they are both about 1/4 inches. I replaced
all of the hardware.
Cowling mod #4 is finished and will be fitted tomorrow. My approach to
eliminating the nose gear boot is being changed also. I hope it works out OK.

Is there any precedence to converting a plane with the shocks to a plane
without the shocks.
