All you need for this cheat is a bound armor spell (whatever part of daedric armor you want) and you will also need a summon monster scroll or spell.

First you must all your armor and then summon the monster and then cast the bound armor spell.

Then you have to attack the creature you summoned so that he damages the armor.

Then you can kill him. You must then repair the armor quickly and drop the armor before it disappears (it will let you drop it now).

Now wait for the timer of the armor to run out and it won't go away.

You can then pick it up and use it as much as you like.

Also it's really cool as it doesn't weigh anything.
