What speakers are you driving? And is the power level sufficient for good dynamics and all that?
I need a drill press. I can't even make a clean hole in a metal face plate. I used to own one plus some large diameter hole punches for tube socket holes. I'll get back into it someday.
Looks like you're having fun!

Thanks for the nice comment. The speakers are 15" Beyma concentrics like Tannoys. They 99db efficient. My 2W SE UL 6L6 tube amp drives them loud.
Depending on the job sometimes I just hand drill, others I use a drill press. I have two stepper drills for larger holes. Holes for octal sockets requires my bigger stepper dril.

Those are really efficient speakers giving you a wider ranges of amps to play with. I have a pair of speakers down in the basement that seem to require 100wpc or so before they 'come alive' with decent dynamics.
The last time I used a stepper drill was on the roof of my pickup truck to install an antenna mount for a HAM radio whip. Talk about scary! Too big and I'm in a heap of trouble. Too small and I'd be there for hours filing it out with a round file. ;-) Wish I could find my Greenlee hole punches! Lost them in a move.
I also use these speakers with a pair of DIY 150W Tripath Class D monoblocks. That's the beauty of high efficiency. They also work really well with my DIY 2W 6V6 SE UL. The only draw back is the lower 3db point is about 50hz with some output at 40hz. They are in 170ltr reflex I closures. For me that's fine I mainly listen to classical.
