Sounds good now you can repair others with the same problem. Al

Nice work mate, I found the problem was the grub screws. Al

Yeah I returned mine but came back the same, maybe they dont know the problem and how to fix it, anyway I found the problem and fixed it,,,,now no more binding. Al

I had exactly the same problem so I sent it back for warranty repair, after 2 months it came back exactly the same, so I pulled it apart and found the problem and fixed it. Refer to page 20 my post 486 and read on. https://www.cloudynights.com/topic/586532-new-skywatcher-az-gti-goto-wifi-mount/page-20

Changed the clamp to a smaller one.

Gavin the spacing diagonally is 28mm hole center to hole center and 19mm from hole center to hole center where your clamp is 20mm and a 6.5mm hole by the look of it. I found the clamps I had the predrilled holes were 25.5mm and drilled for 1/4” bolts. The AZ-GT I bolts are M4. Al

I never liked the AZ-GTi saddle clamp so i removed the tin cover inside the clamp which revealed 4 screws, i removed them and the clamp then I dug out a saddle from the spare parts box, i had 3 but 2 had pre-drilled holes in the centre that didn’t line up with the AZ-GTi mount holes but the ADM saddle had no pre-drilled holes so i removed the AZ-GTi saddle and clamped it on the back of the ADM saddle and drilled 4 holes and i now need to go the the bolt shop on Monday and get the correct length bolts then countersink the holes,,,,,easy-peasy.
