Hi guys,

   I have an original FSQ106 (vintage before FSQ106N). I'm having a really hard time locking down the Camera Angle Adjuster (CAA). Is this a feature or is there something I can adjust or fix to remedy this problem?

 

   Thanks!

edit: the fsq CAA is a slightly different design, with three set screws (0.035” Allen wrench), which are sealed in with lacquer - requires a dab of acetone to release them.  I've sent you a PM regarding the instructions.

Here's an update of what I did to fix the problem. After help from Simcal, I came to the conclusion that the CAA was slipping because of the weight of my image train (camera + filter wheel + oag). When the scope is unmounted and placed on a table, the locking was solid. But once it was mounted on my mount, the CAA easily slips.

 

My solution is cheap and simple. I added more friction using anti-skid pads available from Home Depot. They have sticky backs and are easily trimmed with scissors so that they can be stuck to the rubber stopper that is part of the CAA locking mechanism.

I still need to tighten the locking screw with a pair of pliers with another 1/2 turn to stop slippage. But it's a lot better than before.

Seems that grease gone through the rotary piece inside CAA. So when you tight the lock down, the rubber stopper doesn't contact with metal but grease. Avoiding the firmly locking.

I repared once a CAA with this issue by disassembling it, cleaning all grease (including rubber stopper) and regreasing correctly.

Thanks for the info. If my fix doesn't work, I'll disassemble and clean.
