During one of my evenings, I met another Astram who owned him EQ-6.

While discussing, he told me that he had added a part on the altitude claw of the mount, so that the adjustment screw (the famous screw that twists if you force ...), is more from the front than the original, where it presents itself frankly at an angle.

Indeed, these mounts were designed to operate in different latitudes from ours, which explains this discrepancy.

Finding the idea appealing, I decided to adopt it. But in addition, I would like to obtain a punctual contact of the screw on the claw, and this over the entire adjustment stroke.

Suddenly, this contact will be made by a rolling ball, soaked then drilled and threaded in its axis, integral with the claw, which will press on a stainless steel plunger, threaded to receive the screw.

The claw will be drilled and tapped to receive the grub screw of the ball. A side hole is provided in the pusher to allow the insertion of a pin, for tightening and especially the possible loosening of the screw. In order to allow the pusher to pass, the frame had to be slightly milled. A trace of paint was made to check the effective passage of the pusher. The same processing has been reserved for the pusher, in order to control the position of the contact over the entire altitude travel. It can be seen that this contact takes place near the axis of the screw.
