Don't, unless you're one brave sonofabitch. 
We have a 7' double-wide garage and one of the door cables rusted through at the bottom and broke a few weeks ago. I had to cut the other cable to let the other side of the door all the way down, so mice wouldn't get in. Last time I had a cable break, I had some garage door repairmen come and fix it They charged me $250, so I decided to fix it myself. The cables were only $15 for a pair at Ace Hardware, and putting them on was the easy part.
I had to make two 18" iron bars to wind the torsion springs, which is pretty dangerous if the winding bar happens to slip out. After getting them wound, the door actually came out better than when the repairmen did it last time. They left a 1/4" gap on once side, but now it's all the way down on both sides and it saved me $250.
