From The Driver's Seat
By Joe Janssen
Thank you to the members who
attended the Pineapple Tournament.
A great thank you to Bill and
Shirley and their team for organising once again a great 19th
O.D. Inggs Memorial rally.
I enjoyed the run which was
different from previous years. The longer stretches and less through
village driving went down very well with all the competitors.
There were quite a few
challenges for the drivers ( including myself ) to keep their horses
on speed. After doing very well until the last control of day 1,
where we had to do some creative time recording ( where we subtracted
instead of adding time ) we had to say goodbye to a first place.
Neville and Susan Koch took
first place in their 1975 Alfa Spyder, in second place came Colin and
Anne Meyer, from East London, in their 1975 Mercedes 220s
Third place was taken by Dave
and Daphne McNeill in their Triumph TR3, in fourth place was Bruce
Yendall and Peter Owen-Smith in their 1941 Chev Coupe and in fifth
place Ron and Pam Gush in their 1934 Austin 10.
Thanks to them the AVCMC is
keeping the Club Trophy.
Nice to see that all starters
finished. No work for Dave and Christiane who were the sweep crew.
Thank you to all our sponsors
and competitors, without them we would have no rally.
See you at the Bathurst
Agricultural show

Thoughts For The Day
A young man enters a book
store, “Do you have a book called, "Husband – the Master of the
House"?
Sales Girl : “Sir, Fiction and Comics are on the 1st floor!”.
(Pinched, with thanks, from the MG
newsletter)
I've learned....
That being kind is more important than being
right.
(Sent in by Shirley Martin)
I can't remember where I found
this:
There was a young student from
Boston,
Who drove around town in an Austin.
There was room for his ass
and a gallon of gas.
But his balls hung outside and he lost 'em.

OD Inggs 19th Memorial Run
by David Dicken
DAY 1
As we write this report it is
a grey, wet, miserable Monday morning. How lucky we were to have had
two nearly perfect days of weather for our rally. Scrutineering ably
taken care of, 15 vehicles set off in fine style after a brief
appearance of the unique toy Fiat delivery van for good luck. The
“borrowed” MG was a welcome reminder of a lost friend.

At the start, Top: Rodney and
Ruth Idris in their 1951 Morris Minor
L to R: Bruce Yendall's Chev, Dave McNeill's TR3, Trevor Hoole's 3Ton
Chev
The scenery after Grahamstown was beautiful, one of the most scenic
in this part of the world. A number of baboons were seen as we went
along and having passed through Adelaide, which appeared to be in
good condition, we arrived for lunch in a delightful Tea Garden
restaurant on the outskirts of Bedford. There we saw a remarkable
collection of wooden furniture, vintage hand tools and indigenous
timbers. Whilst admiring the Citroën DS 23 belonging to John Pringle,
it was noticed that it was supplied new in 1961 to Ryce Motors in
Nairobi, Kenya. By complete chance I lived nearby the Ryce family
during the seventies. John showed us the original delivery invoice in
the grand total of 900 Pounds, inclusive of shipping costs, etc.

From there, the 114 kilometers
leg to Grahamstown via Carlisle Bridge was a real test of skill which
caused many navigators to run somewhat ahead of themselves. There
appeared to be some confusion regarding the location of the Marshall
who was waiting patiently for the tail-end Charlies to hand in their
STC sheets. All is well that ends well, as the saying goes. Then back
at leisure (some via the Pig and Whistle) to the Ski Boat Club and a
well earned supper later that evening.
Day 1 results were food for thought.

DAY 2
With all the signboards of the
previous day having been handed over, Don Johnson set off into the
Bundu. An early start at 8.30 saw the entrants leave again but
regrettably Roger Darkes’ navigator Sue was not able to continue the
rally. Fortunately he found a “younger lady” to assist him.
The route took us along the
well known road to Alexandria passing Marshall No. 1 at Kenton Eco
Estate. Arriving in Alexandria we took the turning to Salem but the
route schedule required a U-turn outside the impressive Kikuyu Game
Lodge. This winding and heavily wooded road through game country was
new territory even for some locals.
Having returned to Alexandria,
we were confronted by serious road works which caused delays. Bill
and Shirley had made a plan to take care of this problem. At the end
of the lengthy road works we made our Tea stop at the Tam’Jazi and
STC sheets were duly collected. A new arrangement for the Start Board
had been made which meant that the competitors had to negotiate their
own way through the road works problems and to park as best as they
could on the verge of a very busy R72, with trucks careering by in
both directions. It was a credit to the drivers that they managed to
leave safely and on time. With “God Commands” well noted, all the
entrants made their way back without mishap to the Ski Boat Club.
For the Sweeper and his
Assistant, this had been a very smooth and interesting rally.
Comfortably seated in the Club people were able to relax with their
drinks before going into lunch.
At this point the final
results were posted on the wall and everybody looked eagerly for
their names on the list. With very little surprise we discovered that
Neville and Susan Koch had done it again in their faithful Alpha
Romeo Spider. A very good lunch was enjoyed by all and the prize
giving was received with much applause for the winners and gratitude
to Bill and Shirley Martin together with Mike Newlands and their team
of helpers for a rally very well organised in every respect.

Pineapple Tournament Golden Oldies
Night
by Ron Gush
It was sad to see only 8 cars arrive at the clubhouse for the drive
around and display. In 2014 we had no less than 17. What happened in
2015? There was no report in Fanmail - was the Scribe away
perhaps? Well done to the faithful stalwarts who did turn up:
Mike Newlands - Alfa
Joe Janssens - Merc
Robin Duggan - Cobra - nice to see a car in super
concourse condition!
Mike Legg - MGA
and
- Morris driven by George Galbraith
Bruce Yendall - Chev
Roger Darkes - Jaguar
Ron Gush - Austin
Golden Oldies Night is the event where all past players over age 60
are invited and remembered. It was good to see old friends and
members who had not brought old cars.
As usual there was a lot of interest shown in the old cars

Tailpipe - Ackermann steering
geometry
Extracted from Wikipedia, the
free encyclopaedia
(Editors
Note: Further to an interesting discussion during a noggin a short
while ago, I thought this might interest our readers. I also found
out why my Spittie steering geometry seems so "badly" set
up. It is designed for racing, not puttering around - so I am going
to have learn how to drift into a parking bay! See the last paragraph
below)
Ackermann steering geometry is
a geometric arrangement of linkages in the steering of a car or other
vehicle designed to solve the problem of wheels on the inside and
outside of a turn needing to trace out circles of different radii.
It was invented by the German
carriage builder Georg Lankensperger in Munich in 1817, then patented
by his agent in England, Rudolph Ackermann (1764–1834) in 1818 for
horse-drawn carriages. Erasmus Darwin may have a prior claim as the
inventor dating from 1758.
|
|

The intention of Ackermann
geometry is to avoid the need for tyres to slip sideways when
following the path around a curve. The geometrical solution to this
is for all wheels to have their axles arranged as radii of circles
with a common centre point. As the rear wheels are fixed, this centre
point must be on a line extended from the rear axle. Intersecting the
axes of the front wheels on this line as well requires that the
inside front wheel is turned, when steering, through a greater angle
than the outside wheel.
Rather than the preceding
"turntable" steering, where both front wheels turned around
a common pivot, each wheel gained its own pivot, close to its own
hub. While more complex, this arrangement enhances controllability by
avoiding large inputs from road surface variations being applied to
the end of a long lever arm, as well as greatly reducing the
fore-and-aft travel of the steered wheels. A linkage between these
hubs pivots the two wheels together, and by careful arrangement of
the linkage dimensions the Ackermann geometry could be approximated.
This was achieved by making the linkage not a simple parallelogram,
but by making the length of the track rod (the moving link between
the hubs) shorter than that of the axle, so that the steering arms of
the hubs appeared to "toe out". As the steering moved, the
wheels turned according to Ackermann, with the inner wheel turning
further. If the track rod is placed ahead of the axle, it should
instead be longer in comparison, thus preserving this same "toe
out".
A simple approximation to
perfect Ackermann steering geometry may be generated by moving the
steering pivot points inward so as to lie on a line drawn between the
steering kingpins and the centre of the rear axle. The steering pivot
points are joined by a rigid bar called the tie rod which can also be
part of the steering mechanism, in the form of a rack and pinion for
instance. With perfect Ackermann, at any angle of steering, the
centre point of all of the circles traced by all wheels will lie at a
common point. Note that this may be difficult to arrange in practice
with simple linkages, and designers are advised to draw or analyze
their steering systems over the full range of steering angles.
Modern cars do not use pure
Ackermann steering, partly because it ignores important dynamic and
compliant effects, but the principle is sound for low-speed
manoeuvres. Some race cars use reverse Ackermann geometry to
compensate for the large difference in slip angle between the inner
and outer front tyres while cornering at high speed. The use of such
geometry helps reduce tyre temperatures during high-speed cornering
but compromises performance in low-speed maneuvers.
