Hi Bojan,
There is so much to think and plan for. Many good alternatives goes away because of too high cost.

But now after I have clean the mount and done some measurement I get a better overview of the alternatives. I wrote them down on the second page:

Maybe it's easier for me to implement a kind of semidirectdrive on the shaft of the worm gear. But still need a gearbox, a builtin planetary gearbox with low backlash.

I'm waiting for the roller bearings I ordered and still looking for shims, I think I go for steel shims if I find any. Inner diameter 40 mm and outer 56 mm, thickness 0.1 to 0.5 mm.

Many thanks for the links and tips!
