Apple Macbook power cord repair

My Mac power cord was frayed and the wiring was exposed at the wall wort.  I reinforced the cord by cutting it, fitting some shrink tubing over the worn area, and soldering the cord back together.

Tools needed:
-wire cutters/stripper
-soldering gun & solder
-shrink tubing and heat source (lighter)
-soldering helper

Step 1 Cut the cord

Obviously, unplug the power cord first.  I cut my cord about a foot from the wall wort and then stripped the cord to expose the wiring.

It is better to stagger the solder points so they aren't side by side. Also you can add some epoxy under the heatshrink for more strength, especially if you add some stiff object like an additional piece of scrap wire or plastic for strength, a splint essentially.
