Jerry - I realise that it may come across as slightly dim but this
is
not a troll. Attempt to get your head around the idea that not
everyone
has an interest in the same topics as, I presume, yourself and have
very little 'common knowlegde' to go on in this area...

In which case you shouldn't be contemplating doing something that
could kill if you get things wrong. Competence to do something is not
just a wish to do something...


I happen to have a copy of the Reader's Digest DIY 'bible', snip
