I don't use scales. I tilt the assempled, fully loaded optical assembly up on the front edge of the mirror box until it balances, and using a carpenter's level mark a vertical line on a piece of cardboard taped to the box (up from the point of support under the front edge). Then I repeat tilting it up on the rear edge. The intersection of the lines marks the center of balance. I've done this with all of my homebuilt scopes, and it has always worked perfectly for me.
