Step 3: Reconfiguring (part 4):
I always feel like I need to post enough actual progress on my pedal to keep this thread from getting locked or deleted for being primarily about sexual euphemisms.
I've started cutting a window out of the lid. Makes the most sense (Thanks, Duck). I do happen to have a Dremel-like high speed cutter, but, alas, I can't use it because I can only build while the kids are sleeping. So, I'm doing this with drill bits, a mini hacksaw, and files (I'll switch to sandpaper when it gets close to final size).
I'm steering well inside my markings so I can enjoy some beer while working (for now).
