Finishing over Signatures

I was approached by a local music venue about finishing over the signatures on this Dean guitar. I have finished over signatures before, but never an entire guitar. The main challenges, as I see it, with this endeavor is prepping the existing finish. Cleaning the existing finish without disturbing the signatures will be time consuming enough, but abraiding/sanding the finish will be cost prohibitive. I have already experimented on a test…

Why do you think they faded? Sunlight, chemical issue, abrasion?

Epoxy Pore Fill question

When using epoxy (either silvertip or epoxy), I try to sand back the epoxy on the surface and only leave it in the pores. I'll start the process with sanding to 320g or so then using an air compressor to blow out the pores. The challenge that I run into is opening new pores in the process. I use a block of wood and long strokes in an attempt to avoid uneven sanding. Ultimately I'll get a good pore fill but I tend to apply several coats…

Are you having a hard time seeing when you have sanded just down to the wood ? If so, you might try a quick naphtha wipe. It should show off where the surface is still covered with epoxy. Due to the f…

My guitar got smashed.

It was attacked by a Martin Dreadaught on a small mountain stage resulting in a faceplant. The top is Redwood. I was able to get it to glue up fairly well and have done some splice and drop fill on the vertical cracks. I'm curious about suggestions for the deep cross grain areas. I am hoping to not re-shoot any lacquer and just rub out the finish with some Kovax dry sanding. It was never high gloss buff to begin with and it's a personal…

@member Thanks Ian, I also have some ultra thin fill&finish on the way. I will do some experimenting with it and see if it can help me out any.

Experienced Builder and Red Wing Grad

Howdy folks, I'm a 2026 graduate of the two year guitar program at Red Wing (Minnesota State College Southeast). Between my two years at Red Wing I worked at Collings Guitars in Austin, TX for two years in the acoustic neck department, shaping and finish sanding ~2000 necks, radiusing and gluing ~750 fingerboards, and pressing ~100 sets of frets. I also spent a couple months in the finishing department level sanding and pore filling ~300…

Drum Sanding Tops and Backs - When and which sander?

So it seems that a drum sander would be very handy for many parts of a "build from scratch". There are a few out there that cost under $3000.00 that can handle wood up to 4" thick and are wide enough to sand a back or top after the halves have been joined. Jet JWD-22-44 open stand, 22"width Jet JWDS-2550 open stand, 25" width SuperMax 19-38 opend stand, 19" width SuperMas 25-50 closed stand, 25" width Questions: Any recomendations on the sa…

I have the SuperMax 16-32. Works very well. I have experience using an older Jet model. A few things about the SuperMax: The paper changing system is much easier. The quick release feature to raise/l…

Sanding methods/mechanism routine

Good evening folks, lately I'm experiencing some sanding methods/mechanism frustration. Can't explain better than look like I'm regressing at doing it. The only thing changed in my building routine is that I'm currently using a CNC (I haven't used one for some years) for both bodies and necks. I have no problems with necks, but sanding bodies has become incredibly frustrating, specially around the edges. While I keep improving my c…

Help needed to pinpoint my mistakes please!

Hi all, I am a newer guitar tech and after dozens of repairs this particular Simon & Patrick Luthier Cedar top SP6 acoustic dreadnought from the 90-ies with a bolt-on maple neck has been an incredible challenge. It came with a maxed out and stuck truss rod with a considerable up bow in the neck, extremely low saddle with barely any string break angle, so it needed a neck reset. Later on I figured out that it also has a pretty dras…

So what about Re-tops then…. (on a vintage D-35)

Hello again folks, how is everyone! So I'm curious about what people here think about re-tops, who's done them, and what sorta ballpark rates you've charged for past completed jobs. I've got a bit of a wild one here, so strap in if you've got a couple minutes for story time! Back in 2012, I traded an HD28V of mine for a cool 1966 D-35 that needed some work. Basically, the body and neck of the guitar were fine apart from…

Wipe on poly over Z-Poxy?

Hello — I would like to finish a mahogany electric neck and body with wipe on poly (probably Minwax satin) and would like to pore fill with Z-Poxy. I can’t find a definitive word on their compatibility. - Can I just wipe on the poly coats after block sanding the 2-3 Z-Poxy coats? - Should the Z-Poxy be sanded all the way back to wood or just smoothed/flattened? - Is a coat of unwaxed shellac between the Z-Poxy and the wipe in…

I personally like to do a washout of shellac just in case.

looking for recommendations repairing big dent - chipped polyurethane finish

Good morning to all - I have another skill building question - picked up another cheapo electric guitar to practice repairs on. I didn't see the big dent, but figured its an opportunity to practice another type of repair. big chunks of polyurethane finish are gone and the bit that's left has a hairline crack around the bottom. I'm thinking to use wood filler to fill in the missing chunks, and want to know if its best to remove the piec…

I don't know, but I did see enough to consider how to best handle it before I start the repair. I can see that the glueboost might be a good way to approach that hairline crack, but who knows what is l…
