Restoring an antique parlour guitar part 29: Getting the top even

- More fiddling with the top of my d'Orso parlour guitar from the late 19th century. Here I put more work into getting the colour of the top even, and bringing the rosette and purfling back to white by sanding and scraping. Is this the last coat of garnet shellac?
You've got a remarkable amount of patience! The light area on the upper bout, treble side could be matched using a tinted shellac. In case you're not familiar with Transtint, it is a dye stain concentrate that can be mixed with almost anything including water, alcohol, lacquer, off the shelf oil stains, and shellac. The tiny bottles are expensive, but a few drops go a long way.
Ms Gardner, Thank you for sharing this journey. The passion and challenge.of your art in the repair/restoration of this guitar is engaging and fun to watch. Where this instrument may not return the full value of your time, it will proudly display your pride and skill.
+csunset Ditto. I'd advise next time use dust from a wood that matches the tint of the wood around the crack, or darker. Darker comes across as part of the grain. Rosewood dust, in the case of this back.

Very much enjoying your videos
I love your videos, I'm looking forward to your seeing this to completion
Very cool! I don't know how the shellac would respond to heat, but you might try steaming those low spot dents out, the steam should cause the wood in those areas to swell if they are not too big.
+Randy Schartiger look at pt 4 or 5.
looking good..
It's looking very good but couldn't you just paint the white line to match the darker area?
I remember someone mentioning to use nafta to sand instead of water when sanding. Wouldn't it have helped to use the color shellac on the cracked part?
I really love what you have done with this guitar. My wife has an old Suzuki acoustic guitar, that needs some love. I might have to try to restore it to the point it can be played again.
I watched the whole series last night before bed and I'm looking forward to hear it be played.
+Lars de Waardt I assume you meant to say Naptha.. never heard of nafta.?
+George M yeah, used spellcheck and that was how it corrected it :-)
lol guess it needs a recheck speller. lol

Have you tried an experiment on a wood scrap, putting some of the KMO4 over the shellac?
+Sysiphistication I doubt KMnO4 would do anything to the shellac, although it might have an oxidising effect on the shellac maybe, but the word wouldn't be touched I think. Something I've learnt is that it's better to apply KMnO4 to the wood before gluing it in place, as the water expands the wood and marks it tricky to get level
Yes one must be wary of getting water on uncoated wood, it raises the grain too. I looked into hot iron brands and while they are available they can be quite expensive. I've been trying some experiments using India ink. As long as it is clear coated it's useable in some instances. It also comes in colors other than black.
Have you heard of a luthier by the name of Dudenbostel, when he finishes his guitars he said, "it's not how many coats you put a guitar, it's how many you take off." After watching these last couple of videos, I see what he means.
Sue,
What grit paper are you using for this phase on the top? Wish I could work as fast as you!
+Sysiphistication That's 1500 grit
Will you eventually get down to say 2.5K or 3k grit? Is French Polish buffable, or is that too much friction/heat?
