Hi! Paul.(from a MK l Builder to an XS ......!)
Make sure the top moulding is pulled well back onto the firewall to ensure
the empenage to fin area is well overlapping . I needed to have a piece of
3/4" ply across the inside of the start of the fin then drilled through the
lot to insert a long piece of 3/16" threaded bar right through to enable the
lot to be tightened
up together.I put a good smearing of redux on both flanges before mating
together, don't allow the over-riding flange to ride up the register of the
other anywhere, as it makes for lots of filling later.
Make good use of a hand held light behind the joint to judge the thickness
of the joint along the whole length of the overlap to ensure there is a bond
over the entire overlap and flanges , don't squeeze all the redux out . Make
an effort to trowel off all excess redux.
On the spa clearance , my "old man " always said "a miss is as good as a
mile "! There isn't a lot of clearance because I notice mine always only
just clears when we do the rigging.! We have often missed the the starboard
socket with the PORT SPAR THEN IT JAMS AGAINST THE SAID BOLT HEADS

Subject: bonding in the cockpit module
Hoping to bond the cockpit module into the canoe this weekend - with some
trepidation. Anyone got any hits, tips or major disasters to avoid. Second
thing, I did a trial fitting of the wings to the cockpit module the other
day (used the dummy spar to set the bushes etc.) - very relieved to find it
all lines up but how much clearance have folk got between the stbd spar and
the bolts connecting aileron push rods to CS8 - seems awful close.
