Rotary Gap Design

Hello all,
there is some good discussion going on concerning rotary gap design 
especially with regards to electrode attachment. I haven't heard much 
said about balancing the rotor. My friend Bob Svangren has built a 
number of rotary gaps and one thing he is very concerned about is 
balancing the unit. He has a balance machine used for model airplane 
props or other small items. On a rotary I built and Bob helped on, we 
spent a lot of time balancing and removing small bits of mass ( hole drilling).

The end result is a very smooth running rotary.

As an aside, my next rotary gap set up will be using a metal rotor. I 
am going to try a special saw blade or make a rotor out of aluminum. 
Richard Hull used metal rotors on his machines and they ran many 
extended sessions successfully.
