 I think I've mentioend before that these days my parents would probably
 be guilty of child cruelty or something. My 8th (I think) birthday
 prsennt consisted of things like a woodworking tenon saw, a junior
 hacksaw, a set of twist drills, a wheelbrace (hand drill) to use them in,
 a small vice, and so on.  
 
Now I'm jealous ;-)
I was really interested in that Technic Lego that used to be around - I spent
many an hour designing gearboxes and the like. I'm not sure if you can even
get the stuff these days (or if it's anything like it used to be - gradually
there were more and more custom parts creeping into the model kits, and of
course anyone with a real interest in that stuff built the kit model once and
then used the parts to create their own things)
  I certianly think there are fewer constructional toys
around now than
 there were perhaps 30 or 40 eyars ago. I must have over a dozen
 different educational electronics systems, and none of them are Heathkit
 :-).  As I've said before, I think the Philips EE kits were the most fun,
 but teher were others. 
I was probably around 7 when I got one of those ones with the bendy springs
and a bunch of wires for making connections to components that were mounted on
the board - it was a good introduction to electronics. I don't remember how
old I was when I first tried soldering my own stuff together, though.
  Be careful!. LH threads are always ued for a reason,
not becuase the
 manufacturer is awkward.
 I don;t know aobut compressors, but I rememebr there is some convention
 with gas cylinders and the regulators for those. 
Yeah, I asked around a while back, and it seems that general-purpose
compressors exist with both RH and LH threads for the regulators - there
doesn't seem to be any kind of standard. I don't care which way I have to turn
it to do what - it's a tool that has to be learnt, like any other - so I'd
much rather they used standard parts (although to be fair I suppose they never
thought that someone would be taking the regulator apart!)
