A few more progress shots of the mount I've been working on for my barn door tracker.
I've used a ball lock bolt for azimuth adjustment (pic 2). By tightening the star grip (pic 4) a holding force of 5.3 kN can be achieved! Massive!!! By loosening the star grip the ball lock bolt can be removed and the mount then separated from the base plate (pic 1 & 2). The mount does not yet have a screw for fine azimuth adjustments, something I may work on soon if needed.
It also has an articulated joint which the tracker is mounted for elevation adjustment (these are usually used with aluminium profile). There is a star grip for fine adjustment (pic 3). The articulated joint can be locked into place with the indexing lever on the side after adjustments have been made.
Now I need some clear skies so I can put it into action with my single arm barn door tracker. Don't know how I will go without a polar finder scope, I may need to purchase one to help when making fine adjustments.
I'll be working on a double arm tracker soon and will post up progress shots.
