I've been a fledgling luthier for awhile now, and only do it a few hours a day and mostly on inexpensive instruments. It's a break from playing really, and gets my second love of tinkering satisfied. I refer to Frank Ford's frets.com for info frequently. I've gone to Frank once in the past for info, but now he refers those with repair questions to this site.
Just got my first broken headstock on a Epiphone acoustic. I got the glue up done alright, but infortunetly the owner didn't save the missing pieces. So now I need to improvise. I haven't done the "is it lacquer or is poly test?" but since it's a newer guitar from Asia I'm assuming it's poly. By the way, I have filled poly finishes in the past with tinted super glue, but as you might know it leaves that "drop of oil in a bucket of water" opaque look. Not that it really matters on this guitar, but that I'd get some more experience.
Here's the front of the headstock with missing chunks of finish and wood. I thought I'd try epoxy this time with Behlen burnt umber tinted to get the color close then scrape, sand, and buff. Then I thought I would paint in the darker grain where it would be missing. I know, but I have to try it for the experience. Thoughts from anyone? Finish to put over the top of the painted grain?
Now here's a photo of the back of the neck. Yeah, it's a huge hole and I'm really not sure about this one. Unless someone says something differant, my thoughts are; cut a rectangular hole using a knife (what kind & where?) dremel or saw. Leaving a slight inward taper on the cut. Then take a mohagany dowel and and mirror the taper, cut a groove for the truss rod to move, leave it proud and again...scrape, sand and buff ??? What kind of finish can I put over the bare wood that would work well with the poly? Anyone?
I know this seems like a lot of work for this guitar, but I'd hate to try it on a more expensive guitar for the first time. And, the kid that owns it probably wouldn't buy another guitar. There's not a lot of discussion about matching poly finishes including frets.com, and maybe for good reason. Except for the UV dentist tool and that's not going to happen for me.
Just want to get it as close as I can, thanks ahead for any help anyone can offer...
