Repairing wall warts

Chuck,

   You may not believe it but the best method that I've found to get into
wallwarts is to lay them on a hard surface and smack them with a hammer!
It's sort of like cracking open walnuts. If you hit it on a seam you can
usually pop the seam apart. One of the advantges of doing it this way is
that there's no gap to fill such as there would be if you cut it open. It
takes a bit of practice to learn how how to hit them but once you learn you
can pop the shell apart without damaging anything inside.

   If you don't trust yourself to break one open then the next best thing
is one of the THIN saws made by Exacto. They're about 6 inches long and fit
in the large Exacto handle. The nice thing about them is that they have
FINE teeth (just right for cutting thin plastic) and the blade is very thin
so there's little gap left to fill when you glue the case back together.
The saw blade is about 1 1/4" deep and has a backbone on it to keep it
stiff. You should be able to find one in any good hobby shop.
