simple........make up a bolt on sealable container............add water as required.

I don't know if anyone makes anything that works automatically, but we use to eccentric rings that just clamp on behind the chuck to do offset turning. Basically you just slide them around from opposite sides and adjust by experimentation until you get the balance close. You have to have a chuck adapter made to take these though.

the old grinder principle only its a little finer...

Balance Dynamics (Baladyne) makes some automatic units, but they are pricey. I used their fluidic ones to do a trim balance on grinding wheels and they worked quite well for that. An alternative is an external unit. We use one manufactured by Sigma in Japan for dual plane and trim balancing of our spindles. It takes perhaps 5 minutes to get a good balance.

Thanks Jeff

I shall take a look at the stuff you mentioned later today.

Yup. Lord Active Balancing (formerly Baladyne). We've integrated some (on the CNC side) and they're pretty slick.
