ABSTRACT:
The present invention generally comprises a counterbalancing assembly for a random orbital machine including an adapter and a counterweight. The adapter includes a recess and the counterweight is disposed in the recess and detachably fastened to the adapter. In some aspects, the counterweight is fully enclosed within the recess. The adapter is configured for connection to a drive means for the machine and for connection to an abrasive pad assembly. The drive means is rotatable about a first axis of rotation. The abrasive pad assembly is rotatable about a second axis of rotation disposed parallel to the first axis of rotation. The adapter and the counterweight are configured to substantially counterbalance portions of the abrasive pad assembly not disposed concentrically about the first axis of rotation and forces to which the abrasive pad assembly is subjected to during use.
