Hi Bojan,
The noise reduction wasn't that important, my neighbours will sleep anyway. But I noticed that the old spur gears hade very lot of grease on them, maybe that damped the noise earlier and that's way it isn't that much difference.
Now I have adjusted the worm gear play and the worm driva axial play to be very tight. Indoors it woorks like a charm, but maybe problem out in the coldness later. Then I have to fine adjust it a bit.

On page 15 I have added a stop for the dovetail rail to fit in correct position where the DEC balance point is. It will help a lot in the cold and darkness. Very simple done but very useful.
I have now almost eliminated the play and backlash so it will be very interesting to see how it behave in reality.
