Post subject:  Detailing problem
I'm finishing a yellow siris Weissey,
french polish,
and have a couple of spots about 1/8" round,
where the grain chipped out when I planed the back.
I made a thick paste of f.p. for drop filling,
with the medium amber shellac.
2 coats of f.p. sealer and,
no, this ain't gonna work.
Really dark on those spots, duh .
My fix that I'm thinking are, inlay something over the spots?
No, not symmetrical.
Patch with some yellow siris, try to match?
Dig out the finish carefully,
and soak a Q-tip with alcohol,
get as much finish out as I can, and sawdust and ca,
or, just kill myself.
Don't really want to do the last one.

You could try drop filling with blonde shellac (amber would be way too dark), by melting it with heat so it doesn't shrink like filling with anything involving dissolved shellac. Never tried it, but it might work.

Or fill it with hide glue, and then try to glue a plane shaving pressed in to top it off, sand flat, and then pumice fill to level out the gaps around it. Hide glue should match the color decently enough that any showing won't look too bad.

Inlaying a piece of the same wood might look ok, but isn't that stuff pretty reflective, like you'll have to find a perfectly matched piece or it will stand out as the light moves over it?

Dust and CA would probably be darker than the wood (but not as dark as anything involving amber shellac), but I guess since it's small and probably a bit jaggedy edged, it would just look like a knot or other minor defect in the wood when viewed from a distance, rather than a botched repair. But up close it would likely be visible... but forgivable.

Then again, killing yourself fixes this, and all future problems, so that's probably your best bet.

System 3's SB112 epoxy may be the answer. I use it for pore filling and have successfully filled small chips in Rosewood and mahogany. The one in the EIR I can't even see and I know where it is.

Thanks all.
Last night I filled some smaller chip-outs with ca,
and sealed that, and it' pretty unnoticeable.
Thing about f.p. is you REALLY look at that guitar,
a lot, and see every flaw.
You funny, Dennis.
