We will see the use of ebony banned in our lifetime. Its a shame to reduce it to shavings when it can still be used for so many things! Nuts, saddles, edge bumpers, extensions, etc etc etc...
The wrench was for the bolt that holds the neck support on the bench. It was the start of what ended up being a bad cold...a box of tissues wouldn't have helped!!! ;) Good point on being careful with the finish...the devil is in the details and it's hard to tell on video how little alcohol is being applied...Noah is extremely careful and probably the most patient restorer in the shop and thus does all of our fingerboard removals.
If not saving the old board - we'd plane it off. Zero damage to the neck - done in minutes with a power planer to begin with and then by hand as you get closer. The shame in that - even if not re-using the board there are always uses for the wood.
