Rotary gap balancers



Greetings,

The latest issue of _Projects In Metal_ has an article on making a 
balancing device for wheels such as grinding wheels, etc.  It would be 
very useful for a rotary gap wheel as well.  The device is basically a 
scaled up version of a hi-point balancer.  The hi-point balancer is used 
by the model aviation hobby to balance propellers.   I believe that the 
propeller balancer is too light duty to hold up a 10" disk of 1/4" G-10, 
but it is useful as a source of design ideas.  You can check out one of 
these balancers (hi-point) at a hobby shop that sells radio control 
planes.
