And there you have it! The membership has checked in, and with all good advice/technique on dent removal! I want to mention this again though:
We are talking specifically about a Rogers COB Dynasonic here... the snare frame DOES NOT need to be tightened to the point of buckling the shell... that's not how the design works. It did sound to me that it was over tensioning that caused the dent in kjklives2ride's drum, and not a small little dent/ding... meaning ... he should have no problem by following what you guys have laid out here!
I understand the idea behind the "backing plate", but again, not needed... at least not on a COB Dynasonic as the snare frame won't, not does it need to be, over tensioned... right?! I have yet to see a dent return in a COB Dynasonic that I have repaired as once the drum is set up properly, the customer/drummer is amazed at just how much the snares "float" with this design. I would imagine that one could indeed incur another dent on a different brand/model drum by over tensioning the snares again... and I have no doubt that it does happen! Shouldn't be a concern on a COB Dynasonic though, especially after the drum is set up correctly. :-D
