I set up the tailplane deflections before the top goes on. For the bottom
stop I use a U shaped layup, 4 plies of BID with a second one for the top.
Thin rubber sheet on both to reduce the clonking noise.
Attaching the plywood balance weight guides is also sorted out at this
stage. A 3 ply splash layup is done in the top moulding, (with wax
release). then with the top Clecoed in place it is 5 minute
floxed temporarily to the plywood guides, then cracked off the fuselage
top and the top removed. The corner layups can then be done at leisure,
including the anchor nuts that hold the guides in place. The splash layup
can be easily Reduxed onto the fuselage top at final assembly.
I also use a similar subterfuge to do those awkward layups at the top of
the rear bulkhead.
