Securing finderscope

[CraigB86]

Morning all,

 

I recently upgraded the stock finderscope on my skyliner 150p dob to a 9x50 right angle finderscope. 
 

the problem is when I tighten the screw to secure the finderscope, the attachment doesn’t feel as secure and the scope easily slips out of the attachment.

am I doing something wrong or are there any tips for improving the attachment?

 

thanks in advance!

I had a similar experience with both my SW dobs when changing to a RACI finder, give the finder a wiggle when tightening, it can get locked a few degrees off flush but feel secure until you bump it. I still have to give the tightening screw a good twist to get it secure. I agree it's not the most secure mounting in general. Tempted to remove my finder shoe and drill/tap both that and the finderscope base to a larger size retaining screw and use a star knob that has a nylon knurled thingy at the top to get more torque.

Swap the finder bracket for a 2 screw type.

Thank you both; good suggestions! I guess it will be a case of trial and error and see which works best!
