Normally, I don't drill into nice drums, but I drilled into my DW pre-collectors 14x18 bass to add a rail mount. No problems. Works and looks great. It did have a Yamaha mount which I hated and covered up.
I also drilled into a vintage RB 16x16 FT to convert it into a bass, adding spurs and the rail - no problems (although I do regret doing it now!)
