Bravo Ben! You have achieved where most would have failed!

Congratulations Ben. Nothing ventured; Nothing gained.

Nice video. You are brave.

I think a contributing reason why pianists don't know tuning and maintenence is not traveling with the instrument. A trumpet player takes the same trumpet with him everywhere, pianists may not even be able to see the instrument very long before their performance.
