Often the problem of repairing something is not putting the repair together, but in taking to old stuff apart. A lot has been said about removing nuts and bolts ( and there are a fair number of links here ) but we are also interested in other difficult dis-assemblies.
You will find info on:
* Nuts, Bolts, Screws and Rivets
* Floors and Flooring
* Problems with Motors and Cars
* Light Bulbs
* Musical Instruments
* Power supplies
Look at the comments, sometimes they have more information than the body of the instructable.
