Actually just cleaned up the design to look pretty.
these /'strong magnets were removed from old PC hard drives. They kindof look like Disk brake pads.
I pry'd the "pad" off of the mount. The magnets are brittle. you can see I shattered the magnet on the left. the right one has already been removed in one piece.
I recessed and epoxied the magnets into the side supports.
I epoxied one vertical side support in place and put one screw up through the 1/4" base.
To get the proper spacing for the 2nd support I placed the prop balancer in position between the supports with a 1/8" bulsa sheet between one end of the spacer and the magnet and glued and screwed the 2nd support into position.
this spacing allows one end of the balancer to touch a magnet while the other end is NOT touching anything. Cant get much less friction than this. It spins for a long time....
Note that the prop is off center toward the side that is actually touching the magnet. This would help if the magnets were weaker. These magnets will support the prop even if the prop is on the far side of the support.
On the green balancer with the sloping sides I managed to cut a magnet in half with 1 half on each side. they are not as strong this way but still work.

Thats enough playing around with these balancers. Back to work on completing my Tiger 60....
