it's a lot of work for little gain. but it's a game I've played too.

those tools aren't really suited to scavenging, more to repair.

get a propane blow torch, a box, and some safety gl*****
heat a section of the board until the solder is liquid an then bang it
on the edge of the box, repeat until the solder/components come of.
the trick is to heat rapidly so the heat doesn't have time to damage
the components.
I find with the the fibreglass boards with plate-thru holes you need
to heat until the layers just start to separate. (you hear a popping
sound)
the boards will be destroyed in this process but you're after the
parts right?
probably best to do this outside, or in the garage: all sorts of evil
smelling fumes come out of the overheated fibreglass resin, and solder
droplets stick to synthetic carpet real well.
another way is to cut the board up with a hacksaw or side cutters
and then extract the pins one at a time
