Thats a lot of gear hanging off the back of the scope. Plus with the scope moving and the off-center nature of the load (e.g. the filter wheel) there is a chance that a loosely threaded item could become looser.

 

Probably not likely it will fall off, but might ruin my framing (actually just happened now as I was doing my balance test, the filter wheel unscrewed a 1/4 turn on its own) .

 

Generally (in life) things that are screwed together either have split washers, friction washers, or threadlock to keep them from coming apart.

 

Should I just be more aggressive with my "hand tightening" or is there a better way to solve this?

 

Thanks,

--Ryan

you can probably use the purple threadlock.  It is relatively easy to take apart with hand tools.

I've used Loctite on telescope Finder Scope screws, to keep them from loosening all the time.  You can get Loctite at your local Auto Parts store and most hardware stores.  The purple Loctite 222 can be removed with hand tools.  waytogo.gif

I’ve been using blue Loctite on my equipment for decades now. I think that the new purple Loctite is certainly the safest way for most amateurs to keep things together. Just remember that what ever you use, use it sparingly.

I haven't had the problem.

But then, my hands are certified torque wrenches.

 

I tend to check things often enough to not have a problem.

I have one spacer that just never seemed to stay on.  A splash of purple loctite solved that issue.

 

I prefer not to use it, but I have no qualms about using when if proves necessary,
