Disassembling and reassembling a custom horn, blindfolded.

Y’all, we see awesome videos of pros disassembling computers, toys, weapons, tools and they are doing it blindfolded so I thought about doing it on a custom horn.
I relied a lot on my good hearing not just a lot of experience: you can hear the screwdriver slotting into the screw, the oil dripping on the rotors, and the hardest of them all, the string getting into the holes. Tip: you harden the tip of the string with the torch so it’s not frayed. You do this normally. So if you drag it across the arm you can actually hear it when it hits the hole.
Enjoy!
