With lot of cloudy nights I can spend many hours in front of the computer. The last days I have made two tube rings to the Pentax 300 mm ED lens.
Some photos of how I did it:

As usual a lot of changes during the work. But good enough to do test, only the 180 teeth pulley left to design and 3D-print.
By the way, today I got my HEQ5 mount, it will much better with its lower weight when I'm on travel with my equipment.
