Re: Sergent Couplers (was coupler debate)

Now that is an interesting idea. Wonder why no one else thought of that or is there an engineering problem that would make it unworkable? Might be something to approach the people at Sergent's and see what they say.

Hmmmm. Why couldn't you replace the ball with a polarized magnet? That way you could hold a wand polarized in the opposite direction UNDER the coupler and it would repel and lift the ball. You could also have an electromagnet under the track also polarized oppositely. The coupler might have to be modified slightly so the ball wouldn't simply turn over. Perhaps replace it with a slightly cylindrical magnet.

Yes, but the electromagnet would have to be OVER the track.

The Sergent coupler has a tiny metal ball inside that acts like
the locking pin on the prototype. It has to move upwards to
unlock the knuckle.
