Hi again!

ALMOST done with my first build- SO FAR so good for the most part! :)

Question regarding piezos- at SOME point, I remember seeing something in a video about this- vaguely remember it- and now can not find the video and wonder if I'm just losing it or dreamt it or something! 

So the volume knob thingy (yeah, very girly of me I know) lol I have it coming out of the lid of my cigar box- it however, doesn't sit quite right, and the threads are BARELY above the hole- NOW, what I REMEMBER seeing in a video, was a guy explaining that if you wanted it to sit more flush- you could totally cut down that little bit of medal sticking up as a post.... (see below please!)

See that tiny bit of metal sticking up to the left of the knob? That's the thing I want to cut down if possible!

Is that OK to do? Or? :) 

THANK YOU MUCH FOR ANY AND ALL ADVICE! :)
