I only got the one side done tonight, it’s tougher to Dremel through a nickel than I thought, and also pretty tough to properly jam half a wine cork in there.
I also know I need longer and beefier wood screws, I’ll cross that bridge later, I just used what I got handy for now.
Yes my hand is healing up fairly well already, I’ll probably be more or less fully healed up in about a week or so.
Neat. Once you get longer screws (and more spare change) you can add/remove nickels to tune the vibration damping. I’m sure they would still get accepted as money with a hole in the middle.
