Wickenby (EGNW) Wings and Wheels Air Show June 18th and 19th 2011.
Hi! all Europe and the UK patrons'
Please note there is a small (and obvious typo like" The Kings Speech"!)
in the web page address but it gives me chance to sing about it also !
The correct address is:- www.wickenbyairfield.com
Full details(and arrival instructions) of the 2011 Wings and Wheels Air Show
event will soon to be found on the web page .
It's quite possible that the annual event of Project Propeller will also be
at Wickenby but the weekend prior on Saturday 11th June so we may get to
share the same Marquee the following weekend with more reasonably priced
evening entertainment for the Saturday 18th June.
Unfortunately our date clashes with Aero Expo at Sywell that weekend so why
not have a "flying" visit to Sywell then come over to us for overnight
camping and attend the evening event or even do it in reverse leaving us on
the Sunday morning for Sywell. Our Air Show plans are "something else" and
will be a privilege to watch.
Regards
Bob Harrison G-PTAG

Will, and others,
The play is because the black pins are undersized about .007 I think. The
main pip pin is about .499 so only a tiny amount of play is available.
Normally, the oversized bushes allow what appears to be excessive play when
the wings are not rigged. When the plane is rigged, those sloppy bushes get
hard to align unless you were superman during the cockpit module build up
and got the fuselage and wing bushes just perfect. I only have two
aircraft that align so well, the wing pins slide in easily, but that is only
at 85 degrees and with the tips held just right. Hotter or colder, or with
an untrained assistant, it is tougher to push the pins in. So what to do?
Since none of us is superman, I many times have re-aligned the bushes on
final wing rigging by heating my spare tapered black pin until just too hot
to touch, but not sizzle (180F), and ram it home. Let it set overnight and
the three bushes get aligned. Once in a while, I do have to put my 1/2 inch
reamer into the pilot side hole and knock a thousandth off for a nice hand
fit of the pip pin because of the tighter tolerances.
Note: There is a good reason for using the pip pin when doing spar
alignment, especially on the glider wing retrofit. Unfortunately we don't
have the luxury of setting our own bushes with the short wings. If we
follow the instructions blindly and use just the bolts, you won't quite get
perfect alignment. So just heat the pin and help the bushes align.
Please do not overheat your existing wing pin and destroy the heat treating.
At 6 Gs, you would not believe the shear load on that pin.
So don't rip everything out just yet, try a bit of heat and patience. It's
worth it.
Regards,
Bud Yerly

When I have help with the rigging then it is quite easy to locate the pins
in my case=2C although the glider wings are quite a handful or two. But on
my own it is more difficult. A couple of years ago I inherited a tapered 1/
2 inch pin from an aircraft engineer and that works just fine. I tap it in
carefully with a plastic hammer=2C and can then insert the pip pin into the
other hole with ease. I don't now where one would buy such a tool.

bushings
For
the assembled wisdom
I
have a little slop in the main spar pins when I put them into each bushin
g
separately - "a little slop" means when I wiggle the spar pins the ends m
ove
about 1/32.
There
is no slop when the whole thing is assembled and the pins are a light pus
h
fit.
Is
this normal?

Hi Y'all...
I'm wondering if anyone can recommend a method for attaching the
joined end of a thermocouple to a flat aluminum surface...I've some
situations where clamping is not possible...I expect to have
temperatures in the 150 to 200 deg. F. range...will be measuring
coolant temp at inlet and exit areas of radiators...(non-Rotax
powerplant).
Thanks,
Fred
