Very interesting. I am curious what the interior of the elevation pivot / bearing / worm gear assembly looks like. I wonder if anyone has disassembled that part?
@@dancevideo2 i did, to rotate degree scale to my desire. Didn't took any photos but you can see brass worm gear with aluminium counterpart, friction brake, washers and nut. Altogether nothing wrong with it and big plus is that everything is easily dissasembled and serviceable.
My sv225 has terrible play on the azimuth axis (lower part). The play is vertical, even after tightening the nut inside the lower part. Have you got the same issue?
If i understood you corectly i dont have that problem. One more thing that is adjustable is worm gear - they have excentric axle holes so you can rotate them to bring them closer to eliminate play. Worm screws with allen head 1,5 or 2mm. Also, you can push brass bushings in, where worm gear axle goes trough, and then tighten that little screw back.
Great tips. Thanks! I also demonstrated how to adjust the tension on the axis of rotation in the following video on Astrophotography Japan. ua-cam.com/video/35LGe8CQZ2k/v-deo.html
Very nice
I found the degree scale screws to be .035 in hex. I tried 0.9mm but it was not as tight.
Awesome video! Very helpful. Where did you buy the aluminum strip? Did you have to cut it to size yourself?
@@kbeary33 had a piece at home laying around. Cut it by myself to right dimension and shaped it

It sounds as if SV Bony's SV 225 has more cons than pros towards it. They have a better idea but thats not it. IT has my vote not to buy...
