What does 'swg' mean ?

Any ideas ? It is something to do with the metal used on the chassis.

standard wire gauge
Google it!

Found it. Very technical stuff.

not all that technicall, put simply its just a unit of measurement displayed in fractions of an inch. easy! 10g is a 10th of an inch 16g is a 16th of
an inch. how is that technical?

Hmmm..not quite Russ...
Yes 16g is almost exactly 1/16
but 10g is nearer 1/8
and 20g is nearer 1/32
So, bottom line....... look it up on a chart

That's a handy conversion - shame it isn't true for anything other than 16g 
Like many of the gauge systems, SWG numbers are not based on any obvious mathematical relationship to the actual size they measure. The
16g=1/16"=1.6mm relationship is an unfortunate coincedence (and 1/16" is only approximate - it's actually 0.064"
. Here's
some SWG sizes:
SWG inch mm
10 0.128 3.25
12 0.104 2.64
14 0.080 2.03
16 0.064 1.63
18 0.048 1.22
20 0.036 0.91
22 0.028 0.71
24 0.022 0.56
26 0.018 0.46
A bit of research turns up the suggestion that SWG numbers are related by the relative weight of wire of that diameter, with each higher (even) gauge
number being 20% lighter than the preceding one. A bit of maths with the values at hand seems to disagree however, so who knows.
Anyway, there's a big list comparing lots of gauge numbers available
here.
Hope this is helpful,
