I'm quite often building circuits on stripboard and use a lot of short wire links to bridge tracks. Here's a way of quickly making accurate short links. For longer links, look at my NiftyBender
To make a link, just put the tinned copper wire across the jaws of the pliers and squeeze and push up with two fingers (see pic). To do this accurately every time, find the correct width points and mark all round with an indelible ink pen. Cut off the excess wire and you'll have a perfect width link. The ink will get scratched off with use but just re-mark it.
