One photo is better than one thousand words........ ( So you all know that I didnt understand a thing from all of the above)[&o]

Edited: What will be the size of the magnet ( and the hole to be drilled on the hub) . I understand that the hole should be a round one. Is only one hole ( and the magnet) enough?

Some photos will really make this clear... and I must confess that My English is not so bright...

Thanks and regards.
