1960s Silvertone archtop neck pull
Dovetail was 9/16” deep, and 1 9/16” wide at the back. 15th fret was 1 mm tail side of the end of the dovetail socket but a slight angulation towards the headstock landed in the right place. Hide glue, released easily. Nice everyday player, finish and binding beautiful, good spruce top, warped poplar neck.
GlueBoost vs Nitro drop fill
*Photo added* Ding repair on spruce top, 2015 Collings 0002HE #23701. What are y’all reaching for when repairing dents in nitro? GlueBoost fill & finish or drop filling with nitrocellulose? This is a well-used guitar; not pristine and the owner has reasonable expectations that the repair will not be “like it never happened” Bonus question: If there is bare wood, should I seal it with shellac to preserve the color before proceeding to fil…
Neck block for adjustable neck -thoughts on design
I've built a number of classical guitars with an adjustable neck and they seem to gather quite a bit of interest, so i'm currently in the process of looking to refine the design and build. It's quite a simple construction where the neck is held together by string tension and hangs on a pivot. I developed a 3d printed "socket" which acts as the interface between the body and the guitar and allows for some fine tuning of the alignment of t…
Splines: When are they necessary?
Question about splines: At what point are they necessary? My question is primarily regarding the crack to the left between the bridge and the sound hole as well as the crack at the upper bout that runs along the fingerboard extension. I have already glued them both and used the TJ cleats that run the full length of the cracks. I have already splined the lower bout crack that runs from the bridge to the binding as it was super gappy and d…
Retopping a ladder braced Stella - dimensional questions
I am repairing a damaged Stella parlor guitar. The original top was birch, plain sawn at 0.100 inches thick, ladder braced with multiple beefy braces and irreparably split, warped and generally separated from the sides. I want to keep the instrument ladder braced with a movable bridge and upgraded tailpiece, all firsts for me. I would be grateful for input on 2 issues. 1. The new top is Adirondack spruce that I’ve reduced to about 0.110…

Wood Pergatory and Storing it for Future Use
Greetings and thanks in advance for your help. I live in one of the most inhospitable places in the world for wood storage (Mojave Desert CA) and later this year will be moving to another more inhospitable place (Sonoran Desert, Buckeye AZ). The realative humidity is currently 16% and that will drop when summer comes. I'm attempting to collect and store wood for future builds and today I spent some time wrapping all of it in seran…
Wood Supplier
Greetings, I was wondering if anyone has expierence with good a supplier for red spruce, preferably old growth, that they would point me to. This would be for acoustic tops/sound boards. From the reading I've done, it seems that the "Adirondack" variety might be the prized piece to get. Haven't decided if torrified is what I'm looking for. I'm also going to need to get brace wood of the same species. Any and all suggestions are…

Aging Toner on a Sitka Spruce Top
I'm fast approaching the finish coating of 2 acousitcs. The sitka spruce tops are really bright. I'd like to tone them down a little and have been scouring the web for methods. Seems like adding amber toner in either the sand sealer or more likely the first set of nitro lacquer coats might be the the ticket. I see Stewmac has a Colortone stain called "Vintage Amber" that can be mixed into the nitro. Anybody have expirience with this pro…
Gagliano 701 Jumbo Neck Joint
A Gagliano Jumbo probably made by Kay in the 1950's. It looks like this had a previous neck reset based on the shims and some sloppy chisel work. I removed the 14th and 15th frets because I had read that these might have a straight tenon. I didn't need to drill any holes for heat, as the spruce shims both split in half after the fretboard extension was released. The dovetail is about 11mm long, the pocket is 14mm deep, and the 15th fret…
More Tanglewood bridge issues
The COE reviewed this bridge disaster in January, a Tanglewood acoustic given to me that had the bridge ripped off as well as some of the underlying top, and an attempted repair with spruce veneer (COE video link https://www.youtube.com/watch?v=AlpOIWQrAlw&t=2685s). The general opinion was to install a bigger bridge plate. However, once I removed the existing bridge plate, I found that the underlying repair had not been fully done,…
Repairing braces that do not close against soundboard
Hello Friends, I've had a vintage Epiphone acoustic stored at the shop for almost two years and it's about time to wrap it up. That never happens, LOL. It has a few loose braces, which is a repair I've done in the past. The problem with this one is that no matter how I jack up the loose braces from the inside, some parts of some braces simply do not move enough to come in contact with the soundboard. This is happening in a couple…
1950s Gibson LG-3
Hi, I have a 1950's Gibson LG-3 that's had some poor work done to the spruce under the area of the bridge where the spruce has pulled away and or been sanded excessively. It's missing about .020-0.30 thou of spruce and I'm wondering/looking for advice about how to go about splicing in a thin piece of spruce before I re-glue the bridge. Please see pictures attached. My main questions are: glues for the patch, should the patch be mitered…
Cracks in acoustic top
I’ve been building electric for a few years but decided to make an acoustic this time. I have some German spruce panels I was going to use for the top. While running it through my drum sander to dimension it, I noticed that both panels have matching 6-8” cracks so the original blank must’ve had a split pre resawing. Would I still have good results if I glue the panels and move on or should I buy a new top set? (I can’t return what I have…
