I would like to share with you the mean I use to easily adjust the balance on the Dec axis. I have made a modification to the dovetail so that I just have to turn a knob to precisely adjust the balance. I needed to use a PTFE spray so that the dovetail slides without effort.

This is not patented and I strongly invite ASA to improve this design and add this very useful feature.
