Dear Sir or Madman
This is a shot of the driver with the plate minus the magnet and the back plate.
A Shot of the jig holding the magnet. Notice the slot on the side that allows for the clamp to squeeze the magnet to hold it.
This is a shot of the speaker sitting in the jig. The Pencils and rubber bands allow the cone and coil to go as far forward as possible. This allows you to lower the magnet into the front plate without smashing the VC.
The band clamp is tightened to hold magnet and when loosened the magnet pulls itself toward the plate.
By tightening and loosing the opposite thumbscrews which are at the same height as the frontplate on which they clamp onto you can move the pole and magnet in a controlled way. When you get it close to centered you can take the pencils out and lower the cone and coil to the pole. A little fiddling with the thumbscrews and the pole will center, provided the VC isn't damaged.
Now make some marks on the basket and PVC to line it up again, but this time with epoxy.
I have some more pics I will add later.
A Voice Coil with no rub... so far.
