D-16GT Restomod

And I use the term loosely. I got this guitar off Craigslist. It wasn’t stupid cheap, but what I paid and what transpired are “OK”. So what transpired was that in JUST the right light I noticed blotches of light coloring on the top. From “the house” you couldn’t see it. And, it played OK.

But like I said… from just the right angle in just the right light….

So, since they are less than thirty minutes away I trodded off to Martin with an appointment to see the repair people. Here it was explained to me that yes, the topcoat was separating from the sealer and they had seen this. Unfortunately I was not the original owner and they mumbled something about “this one got out of the building” and the problem was all mine. They could fix it, for $500-$600. They were nice enough to give me a free setup while I took the factory tour. I got it back an hour later and it plays nice. Very nice.

So…. I pondered my options. The guitar is not rare, special or emotionally significant to me so pouring half its value (in good shape) again in to it seemed a little silly. I could play it as it was and hope that the top coat would not separate more. Or, I could have some fun and refinish it myself. Lots of research on line made that an increasingly interesting option. So…..here we go.

What happened, I was told, is that in the early 2000’s Martin, and other major manufacturers, started going away from lacquer as the main product to finish the instruments. Increasingly there were water based finishes, and finishes that had two parts and interesting chemical reactions. We all know the reasons, work place safety and environmental considerations alongside economic reasons being the major players. Some of these newfangled materials didn’t play nice, or needed different processes. It was a process of trial and error. My separating top coat being an error, soon thereafter remedied.

So, it had to come off. Chemicals are a no-no as they would attack the plastic binding. So, after “clearing the deck” sanding and scraping it was to be. There is an argument for removing the neck, but one of the Luthiers I consulted said that with a little care I could probably work around it especially with the finish color I was contemplating, more on that later. Not so with the bridge and pickguard. Pickguard was easy. Youtube yielded hours of video on bridge removal. They all had one thing in common: Heat. There’s really nice heat pads in the shape of the bridge $$…..or you can use an iron. One advantage I did have is that damaging the finish was not a problem as it was coming off anyways. In the end I settled on the iron. So, strings, saddle, pins and pickguard off. Measured the distance from the outside nut to the center of the saddle at 25-5/8″. (Of course after thinking about that for a while….. I got 6 holes in the top that will line up with the bridge… DOH!) Cardboard heat shield although, again, I’m not too worried about the finish at this point, and an aluminum foil heat distribution layer and to protect the bridge. Don’t want to booger that up.

It was heating time, I was looking for 150ºF-ish for starters. In the end I kicked that up a notch, guess is 180ºF, until I felt the putty knife starting to cut through the glue.

So, a lot of wiggling with a thin putty knife and a steel ruler under there, and eventually “pop goes the weasel”. Of it came, nice and in one piece, minimal damage to the materials. I did do a number on the finish around it, but again, I’m stripping it anyways so no big deal. If and when I have to remove a bridge from a top I am NOT refinishing I will have to be a lot more carful, like the guys in the videos. 🙂

Now to scraping and sanding. I like razors, SHARP razors. So a box of 100 please. And sand paper…..

And off to Muppet Labs it went…. sanding worked better than scraping. 150-220-320

And a wipe down with mineral spirits…. looking good. I believe that the problem finish is GONE. Note that even after sanding the pick guard is still very visible. So, I think we’re going to have to put one back on there……
