So, the cracks on the Gibson A-4 are fixed. Now I can clean the fingerboard, do a bit of fret dressing and clean and lubricate the tuners.
This one isn't too bad. First I like to do a cleaning with Simple Green and a toothbrush. Not too much, just enough to lift the surface dirt off.
I can't seem to find this sold in a larger size. I'd like to buy a quart (about a liter) of it.
This mandolin's frets were not sticking out at all below about the 10th fret, but the ones above that were. I probably won't spend much time playing there, but I wanted to dress those fret ends anyway.
So I made a few passes with a fret end bevel file. Notice also how dull the frets look. We'll fix that too.
So I go back with a small fret end file and just touch those edges up - two or three file strokes does it.
Now you can run your finger along the length of the fingerboard edge and it's nice and smooth, no rough or sharp edges.
The frets wind up super shiny and smooth.
There is a touch of wear on the first couple of frets, but it just didn't justify recrowning them. These frets are small to begin with, and I don't want to take off any material.
fretboard finishing oil for the last year or so instead of lemon oil and I love it. The board winds up with a beautiful natural glow and is super smooth.
My container of this stuff will last for years. It just takes a small amount on a fingerboard.
This board is ebony, and now you can see the beautiful brown streaks here and there. They were invisible before the cleaning.
So I used a drop of Tri-Flow lubricant on the moving parts. They've freed up nicely. One or two of the tuners still have a place in their rotation where they tighten up a bit, but they're much better overall.
