Balancing Tires with 23mm hexes

[jpoprock]

Hey guys... I've never balanced tires "properly" before, and I need to. Many of the balancers out there seem to be for 17mm or less hexes, and have a proprietary nut system. I only use either 12mm on my small trucks and 23mm on the big boys. I'm thinking of buying the Dubro Prop Balancer, or maybe making a balancer with some bearings and a steel rod. But my question is... does anyone know of anything specifically for 23mm hexes... with the ability to use other sizes as well?

Thanks!
Jason
