Carlos and Tord,
Instead of using this big and heavy Celestron Clamp, why don't you use 2 Stainless Steel 4 inch clamps. They are very light. I use that on my SkyWatcher and they have been there since I got the scope and the mount is still rock solid. It is also very low profile.
On the photo, I indicate where the clamp screws are, under the camo tape, and you can see the slots where the clamps go through to hold the home made base.
Quick, easy, cheap and effective !
