My domino:

i thought only the blind man's had split axle, and the others had a tounge and groove mechansim.

Wasnt wayne looking for someone willing to dissasemble their domino?
I loosened it up a little, turns much better.
when you take it apart, the 2 halves are self supporting, they dont come apart from the other pieces in that half without alot of force.

Thats what Wayne was looking for. I don't know if he found one or not. Better ask him.
