THE WAY I SEE IT
By NEVILLE WILLIAMS
For all practical purposes
Mr. Fixit has had his day!
For generations, a major raison d'etre for a father,
husband or son has been their ability, at short
notice, to repair household gadgets. But according
to a reader from Berala, NSW, that traditional role
is now at risk. Who needs a handyman around the
modern home when the best he can do with a faulty
electrical appliance is to discard and replace it?
To be sure, I have met a few men
in my day who never have lived up
to the traditional stereotype; who
have even boasted of their inadequacy when faced with anything
mechanical or technical.
But, more commonly, I have been
pleasantly surprised at the number
of men who have relished the opportunity, at evenings or weekends,
to put aside the business suit, the
briefcase and the telephone and to
get stuck into the mechanical or
technical tasks that needed to be
tackled around the family home or
family car.
The reader referred to above is
concerned about one specific area
but, if I've taken the broad brush
approach to his letter, it's because
he has struck a sympathetic cord in
one who feels frustrated by any
gadget which either has to be
discarded prematurely or is subject
to a daunting minimum service
charge and delay for some fault
that, not so long ago, would have
been readily fixable at home. I

Dear Mr. Williams,
I wonder whether you, like me, object to appliances which have been

screws? More and more manufac6

turers, these days, are putting these
screws into their products. What
they are saying, in effect, is: "you
are prohibited from servicing this
device".
The situation is now such that I
think twice about buying any product fitted with tamper-proof
screws. I like to be able to fix
anything I buy or at least inspect the
inside, if the necessity should arise.
After all, what guarantee is there, if
the product does finally break down,
that the company that made or imported it will still be around to fix it?
Consider the simplest of all servicing jobs - the renewing of a power

cord. It is annoying enough that
most appliance cords now come with
moulded plugs, which means that
the plug has to be thrown out as well
as the cord.
Another simple repair job often
made difficult is the unclogging of
electric hair dryers. When people
with long hair use dryers, it is inevitable that hairs occasionally get
pulled into the air inlet. Eventually,
enough gets wrapped around the
motor shaft to stall it. Pulling these
dryers apart to clear them is a tricky
job. I wonder how many hair dryers
have been consigned to the tip for
want of this otherwise simple repair.
The problem goes even further. I
feel sure that some appliance cords
are designed to perish prematurely. I
am thinking particularly of the
removeable cords fitted to electric
frypans and the like. They generally
have a neoprene or similar synthetic
rubber sheath which tends to perish
on exposure to the grease and oil
which is inevitably present. Why are
the newer plastic materials not used
here?
And just try replacing the cord on
a frypan controller. It's impossible!
Yet the cost to replace such a controller is around $30 or more. Is that
reasonable? I think not. I'd appreciate your views on this subject.

Phil Watson turns the clock back
Dear Neville,
I was most interested to read
your comments in the February
issue of SILICON CHIP and your
reference to my recollections of
the pilfering techniques employed
at the HMV factory many years
ago. It certainly stirred up a lot of
memories.
It wasn't only transformers which
were dropped on- to the railway
embankment; the transformers
were often accompanied by the
chassis to which they were attached. And, when I say chassis, I
don't simply mean a piece of folded metal; they were completely
wired and tested receiver chassis,
minus only the valves and dial
glasses. These would be smuggled out later by a variety of ruses.
The drop was usually made from
the factory root - second floor
level - to which employees had
ready access, with very little
supervision. The trick was to hold
the chassis by the corner diagonally opposite the transformer, so that
it landed on the transformer
corner.
The embankment was manmade, consisting mainly of soft
earth bonded by grass roots. Even
so, it says something for the ruggedness of these chassis that they
were able to withstand .such an
unofficial drop test. It's a pity that
the company wasn't in a position to
boast about it in their advertising!
As for the "Trojan Horse" in
reverse, it was part of a much
more serious offence, involving
pilfering on what might be termed
theft on a "commercial" scale.
A team of characters was involved. Only recently employed, they
must have regarded the company's goodwill as a gift from the
gods. Many components were involved but mainly valves. It was
wartime and valves were in short
supply.
For domestic receivers, they
could only be bought with government approval and on a strictly
limited basis. It often happened
that a batch of several hundred
receivers would be completed
before all the valve types required
came to hand.
The receivers would be given a
final test and rough alignment, using test valves in place of the missing types, then stored on racks on
the factory floor until the missing
types came to hand. There could

In fact, the operation had an

culprits. The scale of theft was
such that the police were called in

The latest models use plastic studs

of power cords with moulded plugs,

they might come in handy some day.

a growing collection of freestanding electric can openers that

detail: they no longer reliably open

re-positioning of the support and
cutting wheels would make all the
difference but there appears to be
no provision either to do it or to
have it done.

As for frypan controllers, I seem
to have been fortunate so far;
maybe it's just as well. I'll leave
open for comment the correspondent's suggestion that some power
cords are designed to perish
prematurely. I really have nothing
to go on but I would prefer to think
that the problem has more to do
with ignorance or first cost, than
with calculated exploitation.
Those plastic pillars!
If I seem to be treating S.L's protest in a rather fatalistic manner,
it's probably because there 's
another aspect of modern massproduced plastic technology that
annoys me even more than the matters he has raised: it's the way that
the cabinets of electronic devices
are held together by self-tapping
screws driven into integral plastic
pillars. The method is used alike in
little cheapie devices and units
costing hundreds of dollars.
Brackets, brass pillars or brass
insets are presumably much too fiddling and expensive, when you can
get away with integral moulded
pillars and simple holes to accommodate self-tapping screws. The
idea works - provided the screws
are driven home, first up, by an accurately set tension driver and
subsequently handled only by people with a suitably sensitive touch.
But they aren't and, when faced
with anything but new moulded
cabinets of this type, it comes
almost as a pleasant surprise to
find even a majority of the assembly
screws still functional. To misuse
an in-phrase, the remainder just
manage "to hang in there".
For example, the top shell of a
computer printer that I sometimes
use is held in place by four (or is it
five?) self-tapping screws, inserted
from beneath into moulded pillars,
hanging like stalactites from the
underside of the top shell. In this
model, the top has to be lifted off to
gain access to the mode switches
and, naturally, I've always been
pretty careful in so doing, when a
switch needs to be reset to suit
another computer.
There came the day, however,
when the printer had to be returned
for major service and it subsequently became apparent that, in addition to fixing the fault, somebody
had over-tightened and stripped all
but one of the self-tapping assembly
pillars.
When I complained to the service
manager about this apparent
carelessness, he was singularly
unrepentant. "It happens all the
time", he said. "We just stick a plug
of wet paper in the hole and retighten the screw as normal! ''
Whether he realised it or not, his
company had just lost my further
custom.
Plugging the hole may sometimes
suffice in non-critical situations
and, in others, it may just be possible to substitute a heavier gauge
screw - but you can't count on
either measure. What a boon if someone could come up with a way of
re-lining the hole or, better still, inserting a sleeve to receive a stan-
dard small metal-thread screw.
He/she would deserve a (plastic?)
medal!
The safety aspect
But, getting back to S.L's original
theme, I have the uncomfortable
feeling that the progressive denial
of access to domestic appliances is
not only contributing to a throwmentality, but is also likely to influence the perception about who
needs, or has, the right to repair
anything plugged into the power
mains.
While this may already be spelled out by existing rules and regulations, they are not readily enforceable at a handyman or professional odd-jobber level, where
physical access has traditionally
been easy and repair has required
little more than a modicum of
familiarity, common sense and the
odd spare part.
But close off this existing "grey"
area for any reason and, almost by
definition, we will begin to expose
the borderline as to who has the
legal right to repair what, in relation to anything plugged into the
power mains.
Should this right be reserved for
licenced electricians only, or can
anybody carry out repairs, provided they do not compromise the
specifications on which the device
was granted type approval in the
first place?
Looking ahead, it opens up quite
an area for speculation, extending
to that very nasty one, in this age of
increasing litigation, where individuals can find themselves financially accountable for any harm
caused by activities which are
arguably negligent or illegal. Pursue that one and you could finish up
questioning the role of husbands,
handymen, odd-jobbers - indeed,
anyone without an electrician's
licence!
This is nonsense

SILICON CHIP
Advertising slogans a nonsense
I noted with interest your
remarks on the reluctance of some
dealers to provide service on the
electronic goods they sell.
They advertise extensively, using such slogans as "we stand
behind the products we sell". This
is nonsense. Most electronic
retailers are in the business purely
to sell merchandise. They will
bend over backwards to make a
sale but, as soon as the item
becomes unserviceable, they no
longer want to know you.
There are a few decent retailers,
maybe one in each city. We must
get to know them and maintain
contact. I have learnt through bitter
experience that it is best to give
to say on the matter of routine backup service. His comments appear in
the panel at the top of this page.
When I wrote that first article, it
was with the full expectation that
some readers, at least, would be
anxious to defend themselves as
retailers or to insist that the picture, as pairited, was altogther too
gloomy. But this latest letter merely
adds to by far the majority opinion
that back-up service facilities for
electronic equipment are · in deep
crisis. I commend the reader's advice, learned the hard way: seek
out a supplier in your area who has
a good reputation in this regard and
stick with them.
You may have to walk away from
a few "bargains" in the process but
clearance items may not be all that
attractively priced if, in a few
weeks or months time, you find
yourself lamenting the day you
bought them!
Radio factories in the '30s
My comments on conditions in
Australian radio factories during
the '30s have brought to light a couple of letters, one of them in the accompanying panel from a former
confrere, Phil Watson. The other is
from a Victorian reader who, I
would judge, will not mind me using
his name in full. Of particular interest is the fact that he worked in
the Melbourne Eclipse factory,
about which we junior Sydneyites
one dealer all your business. He
will get to know you and give you
satisfaction, should you ever require service.
In another area, project kits are
fllso traps for the unwary. The
parts are often wrongly selected,
certain parts are missing, or the illustrated instructions are so badly
printed that it is impossible to read
the diagram.
What you wrote was no doubt
distasteful to you but it had to be
said eventually. Maybe a few
dealers will be motivated to "pull
up their socks".

in the '30s knew very little. We
simply assumed that it was much
like all the rest.
Here's his letter:
Dear Mr. Williams,
Your article in February's SILICON
CHIP certainly reawakened some
memories for me.
I had just left school in 1936 at the
tender age of 15 and spied an advertisement in the daily paper reading:
"Boys wanted to learn the radio
trade, apply Eclipse Radio." [There
were obviously no equal opportunity
laws in those days) .
Since I had mode a few crystal sets
and was fascinated by radio, I
prevailed upon my father to allow
me to apply. The pay was fourteen
shillings ($1.40) for a five and a halfday week (44 hours) and I had to
travel 50km from home to work.
Conditions were poor and the factory was old and depressing. I worked in the loudspeaker department
where Saxon loudspeakers were
made. My particular task was to
twist together the four loudspeaker
leads so that someone else could
solder a plug on the ends. I would
then carry the finished loudspeakers
to the test booth wh e re an
"engineer" would apply test tones.
Any rejects would have to be carried
back to the assemblers.
We would clock in and out morning and evening and, from time to
time, there would be a search for
stolen parts. When word was passed
back along the waiting queue that a
search was in progress, the boys
would empty their pockets and a
variety of parts would litter the
ground. I stayed about two months
and what I learned about radio was
harmless.
Fortunately, my experiences did
not totally quench my enthusiasm,
although it was another 25 years
before I trained as a technician. Ten
years later, I was teaching electronics to other young hopefuls though few of them could be said to
be enthusiasts.
Thanks for your writings over the
years. They have been appreciated.
Noel Jackson, VK3CNJ,
(Kilsyth, Vic).
Many thanks, Noel, for your letter and for the glimpse inside the
Eclipse factory. My only real contact with Eclipse products was
when I first joined Reliance Radio
in 1933. Prior to commencing
manufacture on their own account,
they had been selling Eclipse
receivers in Sydney and a few of
them came back through the factory for service or as trade-fns.
While I would scarcely have
been qualified to pass judgment on
them, we juniors certainly didn't
hold them in any kind of esteem.
Gold spray notwithstanding, they
seemed tizzy and tinny in the
American manner, as distinct from
the stolid, solid, battleship grey,
British/Australian approach.
Saxon loudspeakers were no
great prize either and the trade-in
chassis were full of leaky
capacitors and clumsy glass-tube
resistors that could never be taken
at face value. But my most vivid
memory was the wiring, done with
white, rubber-covered hook-up.
Depending on the age and environment, it would variously have
hardened and fractured into a sequence of tubular beads, and/or
have gone all gooey and so
permeated the wire strands as to
render them completely impossible
to re-solder.
Maybe they weren't as bad as all
that but, at the time, they seemed to
be!
Thanks Noel and thanks again,
Phil, for your very worthwhile contributions to the " living history" of
the Australian radio industry.
