Hi Guys,
All you apprentice taught engineers are lucky, I hadn't used a lathe since I
left school until 5 years ago and that was over 20yrs previous! I have been
lucky with my training as regards steam locos having assisted in rebuilding
two from Barry condition. That taught me how a steam loco works, valves,
pistons, boilers, and as silly as it sounds, the theory of combustion in a
firebox. Over the past 10 years, I have come across some really finely
finished locos that go well.... Or would do if the driver remembered to put
coal on the fire!!!! As silly as it sounds, some guys build beautiful locos
but can't run them properly, much to the annoyance of their fellow club
members stuck at signals behind them. I have seen this at several clubs and
it's a shame, the guys have been taught superb engineering skills and their
locos are brilliant, what's missing is the ability to keep a fire in the box
and boil the water.......
The beauty of 12" to the ft scale is you can hit them big style with a
dammed big hammer, (You have to otherwise the bits don't move!) not
pussyfoot around with a gentle tap here and there, although, I also have
seen 5/32" steel plate cut to shape with a chisel and filed to finish, an
artist at work.(I can't even cut my nails straight!!).
To sum up, can you guys pass on your engineering skills,with file and hammer
to those not so lucky, these days kids can't even use a file properly. Basic
tool skills seem to be slipping which is what has prompted me to help the
guys at Imagineering,

Have a look and see what you think, Land Rover are one of our sponsors John.
OK enough of me rattling on, taking up valuable workshop time.

Alan and all Hi,
I have also been lucky to be taught by both the 'Old Engineers' and the mod=
ern pratices that are used in todays industies.
Have served my apprentership at Land Rover around the seventeen factories w=
hich used to feed Solihull plant for building the complete vehicles, At the=
time of my training in the late 1970's and now working for a Motor racing =
team for seventeen years with the latest technology and inovations which i =
now have at my disposall.
Things that were taught in my youth by my father who had been a designer fo=
r Napier in Acton held me in good steed for old and new processes which the=
younger Apprentices of today(if there are any coming through in industry)a=
re unable to pickup if the people whio are training them are too young them=
selves.
A link that i found on the Yahoo Groups pages which maybe of help to other =
who might need or want to do some scraping is=20
