As it is though now with the non-drilled I have to really crank the thumbscrews to prevent movement which is why I like setting them once, and am a little hesitant to adjust mid stream.
Same here – I constantly check to see how tightly fastened those screws are. I check and double check! But really, if you’re aware of it, you’ll quickly become “trained” to tighten that screw well. 😆
I hate to admit it, but I use a pair of pliers on the set screws. Nothing sucks worse than having a suspicion that they just shifted on you.
I used to have that problem until I blue Loctite’d the screws. Even if you loosen them, the residual Loctite keeps them from unscrewing after retightening.
