And given that you have provided 100% verifiable proof that
crosschecks over decades of everything else you say you have done,
have worked and are qualified for there's a good chance that is the
truth as well.

A very good chance, like 100%. For instance, why would I invent
something like that? I was enrolled at Hawthorn Institute, a technical
teachers college and a campus of Melbourne Uni. Caulfield was an
Institute of Technology and ran degree courses in engineering. Caulfield
was set up to run the course I attended, Hawthorn wasn't. I presume the
two entities had come to some arrangement. Why would we trainees get
sent there to do something like basic welding that we were already
trained to do in our apprenticeships?   No, we needed to go beyond basic
welding because we needed to have a higher level of expertise than the
level at which we were teaching. That said, I was teaching welding at
Sunshine Tech from the very first day I took classes. I still recall
nipping across to the Fab Shop and having a bit of a go since I hadn't
done any welding all the time I was in the mining industry - demarcation
issue you see - it was a boilermakers job to do all the welding and I
was very much out of practice. A half hour or so and I was getting back
into the swing of striking a good arc and running nice beads.
After that segment at Caulfield was completed, we went to the Holden
Engine plant and put some theory into practice. It was an impressive
foundry they had there. On the subject of annealing, did you know that a
complex cylinder head, after it has been cast, needs to be annealed.
It's because the cooling process of the casting is uneven and residual
stresses build up in the head. The annealing process relieves those
stresses otherwise you'll end up with cracking before the head enters
service. The alternative is to leave the casting sand, which is an
insulator, in the mould and let the casting cool slowly. It takes hours
and hours to do that. There was a trip to Lysaghts Rolling Mill at
Hastings as well but I missed that one. Can't recall why I missed that
trip but I think that was when my wife was in hospital late in 82.

All those trade related topics came under the broader heading of *Method
Area Studies* - what is being taught, not the how. For instance, we
studied fuel injection systems when few cars had it and the Bosch K
Jetronic system was the main one in use. IIRC, the dealer trainer for
BMW came out to the college to conduct that aspect of the course and be
brought along a 7 series BMW as a teaching aid. It had a Bosch Motronic
system on it, earlier BMW 7 series being equipped with an L Jetronic
system which Holden didn't get until the VK.

I also completed my Diploma of Technical Teaching through Hawthorn
Institute of Education (later absorbed in Swinburn University) in the
mid-80's

At the time, I was teaching Electronics Apprentices at the Army
Apprentice School, Bonegilla, on the Hume Weir, and, each Wednesday, a
couple of HIE Instructors would come up to Bonegilla to run classes for
a group of about 20 - 25 Electronics, Electrical, Motor Mechs, Metal
Workers and Carpenter & Joiners Instructors.

During "School Term Holidays", we would go down to Melbourne for a weeks
'intensive' training and excursions ... even a trip to GMH's Fisherman's
Bend plant where, amongst other things, we saw engine blocks being "run
in", several minutes at max revs .... 'dry', i.e. Red Hot!! When the
siren went off, you soon knew it meant another block hadn't made the grade!!

I don't quite know what our trip to the National Gallery of Victoria was
supposed to teach us!! Maybe seeing all that Art and stuff would take
some of the Tradies rough edges off, or something!!

Institute of Education (later absorbed in Swinburn University) in the
mid-80's

I completed the Cert TT in 81-82. It then took me a four more years to
get the Dip TT graduating in 87. Had I already possessed the Automotive
Technicians Certificate, I would have had the Dip TT at the end of 82 -
and started on a higher pay scale to boot.

BTW, HIE was absorbed into Melbourne Uni. They had some sort of
affiliation but later went the full amalgamation process.

At the time, I was teaching Electronics Apprentices at the Army
Apprentice School, Bonegilla, on the Hume Weir, and, each Wednesday, a
couple of HIE Instructors would come up to Bonegilla to run classes for
a group of about 20 - 25 Electronics, Electrical, Motor Mechs, Metal
Workers and Carpenter & Joiners Instructors.

One of those would have possibly been Bart Pridmore. Another might have
been Ray Retell. Might have been a Martin Busby in the mix. They were
the three automotive instructors at HIE that I recall. Frankly, I am
amazed I can remember them at all.

For the record, my posting was to have been Bonegilla at the end of 82
but my wife had an ectopic during the August hols. As a result, she
needed to remain within cooee of the Royal Women's Hospital so I swapped
postings with a fellow SI, can't recall his name, who was posted to
Sunshine. I ended up in Sunshine (again - was a 1st year SI there) and
he went to Bonegilla in my stead. Later, when TAFE was separating from
the education department, I applied for a position at Richmond. That
turned out far more favourable than Bonegilla would have been.
BTW, Sunshine Tech was where electronics was taught to apprentices. I
knew all the chaps in that department but can only recall a Mick Morambito.

During "School Term Holidays", we would go down to Melbourne for a weeks
'intensive' training and excursions ... even a trip to GMH's Fisherman's
Bend plant where, amongst other things, we saw engine blocks being "run
in", several minutes at max revs .... 'dry', i.e. Red Hot!! When the
siren went off, you soon knew it meant another block hadn't made the
grade!!

Some of that testing ended up being done at Richmond TAFE. When the new
campus was built at Cremorne Street, it included a chassis dyno and a
full engine dyno setup. The engine dyno was idle for a considerable
percentage of time so its use was contracted out. The college won the
contract to do the GM family II engine testing - a programmed series of
idling, acceleration, WOT full load running, cruise, deceleration, etc.
The intent wasn't to run them in or run to destruction but, instead,
simulate real world running on the highway. Still had the odd blow up.
One such blow up took out the dyno for a time.

I don't quite know what our trip to the National Gallery of Victoria was
supposed to teach us!! Maybe seeing all that Art and stuff would take
some of the Tradies rough edges off, or something!!

Some of the tradies had some really rough edges. ;-) I went through
with two groups, commenced Feb 81, totalling 30 automotive tradies in
all the various areas; motor mechs, panel beating, auto electrical, etc.
Ten or more ended up being posted to Richmond so I was in familiar
company during my time at Richmond. It was a huge automotive only TAFE
college and motor mechs alone had 47 teaching staff.

I don't know what you were looking at, but I can assure you it *wasn't*
"running in engines".

Holden, like many others, used to test fire engines on the assembly line
(usually on natural gas) where they would have their oil pressure
checked and their ignition timing finally set before the engine was
passed as "fit" to be installed in a car, but that hasn't happened in
decades. These days, engines generally don't get run until they're
installed in the car and it's started and driven off the line.

What you witnessed would have been just a random batch test, which was
probably done to prove some new mod before it went into production.

Noddy, you weren't there so you have absolutely no idea what was going
on. He was obviously told by people who did know. It was obviously a
testing procedure of some sort. I saw such things at Matech so they do
go on and the purpose is no doubt way beyond your ken.
