Mike
I did mine by marking out the cut out needed on the stbd edge of the
firewall (not a hole)
then made radial cuts with tin snips to just short of the mark (about 2mm
I think). I then bent each spike of metal back, resulting in a radiused
edge. Cut off the surplus and file away any sharp edges and bob's your
uncle. You can enlarge the cut out if necessary with a bit of judicious
hammering until it gently clamps the tubing. I put some electrical tape
over the cut out and a sleeve over the fuel lines where they pass the
firewall.

Not a good idea to go through the stainless tin firewall, it's rather
bendy, will vibrate and maybe even start to crack. Better to go inside the
cabin along the floor from beneath the seat to just behind the rudder
pedals, then straight up and through a bulkhead fitting in the roof of the
footwell. Now it will be easy to access when you need to change the rubber.
This is how Brian Fogg did it, (solid aluminium, even better) and it looks
very neat.
I just had a week's holiday in the local boneyard, Derby Royal Infirmary,
not serious but most uncomfortable. Now I have a crashed desktop and a big
pile of emails to sort, so it will be a while before I'm up to speed. If I
promised anyone anything please email off list.

Subject: | Water Temp Gauge |
--> Europa-List message posted by: "Richard Iddon" <riddon@sent.com>
My VDO analogue water temp gauge on my 912S has been acting up on the
last few flights. Immediately on startup it flickers wildly then as the
engine warms up it settles down but to a higher temp. than it was
running previously. I have checked the connections and wiring to the
sender and all seems OK. I am wondering if :-
a) anyone experienced anything similar & if so, what was the cause
/ outcome.
b) anyone who has fitted a digital system has got a VDO gauge they
would be prepared to sell.

Richard,
I have a full set of new VDO gauges that came with my 912S surplus to
requirements as I also have the Flydat monitor.
Contact me off the list if you are interested. jim@gunn.org.uk

Cheers,
I finally found the photo that shows the AN hardware used for
breaching the composite firewall per recent emails - if that's of use
visualising the installation.............
Ferg
PS: Of course it's not much use unless one transforms from alu tubing to
rubber where applicable.................

Graham - never say never ... John Scott at Cambridge told me he has
fitted AN taper pins to at least one Europa in place of the original
1/4" parallel pins (TP14A & TP14B). This builder was among the folk
who observed that the holes in the torque tube were not very snug on
the original pins from day 1, and John's change was made before the
torque tube entered service. I certainly felt that my own fairly
cautious reaming of the holes for the replacement 3/8" pins (TP14C &
TP14D) gave a better fit than the original. John's taper pin approach
seems better engineering and I'm not convinced that if correctly
fitted they will cause distortion. If I'd heard of it sooner I'd have
gone for that myself rather than the 3/8" pins.
>Only alternative I can think of is expandinhg pins
That also seems quite neat; but how do expanding pins avoid the
distortion problem you fear with taper pins?
regards
Rowland

Rowland,
I would certainly agree with you on the 'careful reaming'. I did mine
likewise and I hope I never have to get them out because they're tighter
than a camel's a**e in a sandstorm!
My original 1/4" pins, on the other hand, were rather less so...
Regards,
Jeremy
