Nice score for a first drum! I like the retro gold sparkle, now all you need is some bell bottom pants and you'll be groovin'. Perhaps learn some 70's funk rhythms as a start point

, you know, so you're in charcter.
I'm with BnB about just getting going with the drum. Personally I wouldn't touch that bearing edge without the proper tools (such as a professional router table etc). Even then, the effort you put into adjusting the bearing edge will probably not make any noticeable change to the sound or playing experience of the drum.
All joking aside, I like the drum!
