One disc need not to be torn apart, put it aside for later.
Take the other and remove the motor disc. There is a star build of coils that we are interested in. This star is the heart of the brushless dc motor. It contains 3 windings that form a 3-pase motor. The three windings are connected together in single point, that is the common connection.
See how it works on wikipedia http://en.wikipedia.org/wiki/Brushless_dc_motor . We have the star version here.
The moving part of the motor need to be mounted fix on the chassis of the other motor. The spindle of the other motor needs to go through this part. We need to make the mounting hole bigger. Use a dremel tool to cut a really big hole into the disc of the motor.
The other motor that we try to use as the basis chassis has some mounting holes that we do not need anymore. Just cut them of with the dremel tool.
