FWIW, the attached photos depict what I have done. Photos were taken during
construction.
When the wheel is latched up, the undercarriage lever is free in the up
detent with no load on it whatsoever.

The manual calls for BID reinforcement of the
joint between the cockpit module and the firewall:
"Scuff sand the firewall and the cockpit module's
flanges abutting the firewall in preparation for
bonding. Lay-up three plies of 'bid' at +/-45,
lapping a minimum of 2.5 cm (1") onto each part. "
It doesn't seem clear to me whether the areas to
be reinforced include the bottom edge of the
forward face of the rudder-pedal support flange
as well as around the sides and top of the
tunnel. It could be argued that the forward face
of the rudder pedal support flange is abutting
the firewall but I would have expected an
explicit call-out of that.
So is the BID reinforcement required only around
the 3 edges of the tunnel, or out across the
footwells too?
Next, the BID strips at the rear of the cockpit
module. I assume they just go transverse, and are
not taken around the corner into the central
tunnel. The build manual (p17-6) does not say how
wide these strips should be, but I assume that a
1" (25mm) overlap on each surface, as for the
CM-to-firewall strips, is OK.
I'm asking these questions here because
Kirkbymoorside doesn't seem well-set-up to deal
with technical queries as present.

Hi Rowland,
I remember scratching my head there too, and for the same reason. Not sure
what others did, but I can report on my version of what the manual meant to
say.
In the front, I only used the plies at the top and sides of the tunnel only,
not at the rudder pedal flanges (only 3 areas of ply). The lower end of the
side re-enforcement plies, stopped at the start of the upper part of the
rudder pedal flange.
In the Rear, they were kept transverse, and the bid strips stopped at the
corner before entering into the tunnel, though it would only add strength at
a slight weight penalty.
I assumed the manual meant 1" overlap in the rear as well, though mine were
a bit over 1" overlap, to clear the flox corner.
Regards,
Greg

Kingsley,
As you know, I admire your work...in this case, I admire your analysis
which anticipated the problem...of which I've been blissfully ignorant.
Do you have a pix of the pivot point along the side of the tunnel?

Fred,
Attached are the only two photos I have that may help.
I was a little fortunate with this project because I had at my disposal, the
drum brake actuator from a Blanik sailplane. The shaft that goes through
the bush has a spline on one end and a removable square piece on the other.
The arm you see attached to the spline is the original part off the
sailplane so all I had to do was extend it.
The alloy bush is home made of course and goes right through the plywood
stiffener.
I made square holes in the latch arm and the doubler to fit over the square
on the wheel well side and stuck it all together with glue. (to think I
didn't even know such stuff as Redux existed before embarking on the
Europa!!) The square piece is discernable in one of the photos in my last
post just below the split pin that wasn't split in the photo !
Twould be a breeze for you Fred !
Cheers
Kingsley
