Magnetic Coupling v1

Autonomous Boat Magnetic Coupling Prototype
The epoxied motor side outer coupling. Notice the inner retaining stop ring.
Before the magnets are epoxied in. Its nice to have magnets to hold them in place.
The waterproof barrier is cemented into place along its flange face.

A view of the waterproof barrier which acts as a bearing carrier for the inner magnetic prop shaft coupling
This is the finished portion of the inner magnetic coupling before being inserted into the other portion
This is where the inner retaining stop ring comes into play. I had to run the motor and insert the inner portion to make sure it did not interfere with any moving bits. The stop ring provided positioning on the dry fit so when cemented in, it was easy to tell where to stop. I then printed a thick ring to cement into place (which you can see installed where the two pieces meet), to provide additional strength.
