don't hit the 500VDC supply with a spanner while hanging onto the metal rack
with the other hand.

Too right. start experimenting on 300v HT lines. Not that they can't do you in,
but you can survive.

You should also respect large heater DC caps also
To quote from Morgan Jones, p236

"A 10 00µF is capable of delivering a very high current into a low
resistance., and wedding ring across the capacitor will discharge it
perfectly. The explosive arc that will be struck at the instant of
discharge will cause the ring to vaporize, resulting in flying molten
metal. Do *not* wear jewellery when working on low voltages"

But, don't let us put you off. Just beware and be careful.
Enjoy!

I'd add the injunction NEVER to work on equipment late at night when tired or
when drunk. These are the times when you may feel inclined to 'have a go' or
listen to a project. Resist. Wait until you are bright and fresh.

I'd add: Never work on a Friday afternoon. You will probably write off all
the progress you've made earlier in the week. Remember to keep Poets Day
Holy. ;-

Slainte,

Agreed. Even 12 volts can be very nasty. I once shorted the starter
solenoid of my car with my watch bracelet, which went to dull red in
about a second! I can recommend Omega Seamasters, they will survive
being ripped off a wrist and thrown across the street..........

Hmmm, I think I gave my brother one of those about ten years ago - black
face, white hands, looked like a mini-submariner with an RRP of about a
thousand?

I have *never* seen him wearing it. Everytime I see him now, the urge to
mention it is growing stronger (like 'if you don't want it, I'll have the
bloody thing back!!') - not helped by all this 'genuine replica' spam I get
on a daily basis....

You can get a midsize version, but the full-size Seamaster Pro is
bigger than the Submariner - and also better made, despite being half
the price! The one that scarred my wrist is long gone. I think that
incident occurred about 1973, I remember because I had a Reliant
Scimitar 3-litre GT coupe at the time.

I wear it's cousin, the Seamaster GMT with the 'sword' hands, almost
all the time. It's become my 'everyday' watch, and holds to about 2
seconds a day fast, less than a second if I leave it on the dressing
table overnight, in the '9 down' position.

Really? The GT coupe was quite rare. A lot more collectable than the
GTE.

I've recently had a drive of a car made just down the road from you, a
GTM Libra. (Made in Sutton Bonnington, usually in kit form). Even
better handling than an Elise IMO.

It's rare because they fell apart.......................

Great looker, but a live rear axle, skinny tyres and lots of torque
are an 'interesting' combination! Mine was a '67 car, LFN 727E.

I do see quite a few of them on my daily work run, which goes past the
factory, but they seem to make about one a week, so hardly a serious
challenger..........

BTW, I don't believe you vis a vis the Elise, as I've chased them down
the road on a few occasions when they got cheeky. Not of course that I
would race on the public highway, occifer............ :-)

Well, wadia knoe? Some good has come out of this (now OT) thread - I
was/have been prompted to speak to my brother with the outcome that the
Seamaster (ordinaire - no Pro or GMT and about 31mm, IIRC) is now coming
back to me!

:-)))

Now, the thing is, will I actually live long enough to see it? He's an
'Aerospace Engineer' and his idea of 'timescale' might not necessarily take
into account my rapidly advancing years.....!!

When I gave it to him I was buying Rolexes (8 in total*, including a 'yellow
metal'** Day/Date for about a third of today's RRP....) and gave most of
them away and/or traded them up, the only remaining example being the
Submariner that my oldest son still has.

I don't ordinarily care about 'posh watches' - didn't really then and don't
now, but I also appreciate the fine workmanship on a 'nice' watch and
greatly prefer a self-winding clockwork watch in any case. Also I'm not fit
to own a decent watch again - I recently left a cheap one (leather strap)
somewhere in the Leylandii hedge that I massively reduced with a chainsaw, a
few months ago! Luckily I wasn't wearing my wafer-thin Marvin (with a nice
porcelain face and also a leather strap) at the time, as I'm usually very
lax at taking a halfway decent watch off to do mucky/heavy work!!


*My 'shooting friend' (and jeweller) offered to get me a 'windmill' for them
to keep them wound, at the time, would you believe? (Not that there were as
many as 8 of them at the same time....!! :-)


**Not even Rolex have got the brass arsehole to describe them as 'gold'
........
