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…

triage neck on LP copy

This is an LP copy from Memphis guitars. It looks like it has had the headstock repaired at some point. Also, there is what looks like some separation of the fretboard near the nut. I don't know if its left over from the repair or if its something new and just trying to go this way. I'm asking the group to look at the pics to help me figure out if any corrective steps are needed. Also from a finish repair standpoint, how to deal with i…

This is a good entry level job. Are you able to flex that crack open in such a way as to get glue in there ?

Nominal Normal Thickness of Barb Thickness for a .022” Tang Wire?

Let me start with this; I'm trying to find the root cause of difficult fret wire installation of two different SM fret wires. I've spent a lot of time gathering dimensions and experimenting with techniques wich could cause the problem. I enlisted the help of a colleague who arrived at a similar poor performance. His solution was to glue the fret ends/ beat the frets in. My "rather" is to find the root cause so I don't have to go thr…

Washburn Neck Reset

I am working on a neck reset on a Washburn Parlor - SN 283552. I have read that the 28 in the SN indicates that is was built in 1928, but the owner thinks based on her research that it was built before 1920. I am assuming a dovetail joint and that I can get into the neck joint for steaming by drilling into the 13th fret slot, but if anyone knows differently please let me know. The fingerboard extension has already separated slightly…

Epoxy glue

Good morning everyone, it is been a while since I wanted to replace my glue (standard Titebond) with epoxy. The best I can find in EU, and specifically in Italy, is the West System 105 with 206 hardeners. Is it any good for fretboard and top gluing or neck gluing? For all the other small task, like top jointing etc I'll still use Titebond or polyurethane glue. Thanks!

Glue for Martin DXME Fretboard Extension

Anyone know what glue type is appropriate for a Martin DXME fretboard extension to secure it to the plastic laminate top (or whatever it is)? I have one on the bench that has broken loose, and I’m not sure what to use. I tried contacting Martin, but they won’t help since I’m not an authorized Martin repair shop. 🫤 Thanks!

When I was trying to glue HPL to the lining, someone recommended Titebond Melamine Glue. Not sure it is appropriate for you, but worth looking into further.

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…

What do you do when you get a knock off guitar on your bench?

I have a "fender", which I believe is a knock off, in my shop. I didn't immediately catch that it was a fake, but as I worked on it it's become fairly undeniable, in my opinion. For the neck — the fretboard is made from two pieces of rosewood, the headstock decal doesn't look right, the truss rod is metric, the tuners don't look like a MIA Fender, and there's no walnut plug on the truss access. The model name being wrong is suspicio…

The Neverending Fret Buzz

Hi everyone, Every once in a while, I come across a bass that simply refuses to stop buzzing. Right now, I’m working on a bass (I won't name the brand, but it’s in the €2,500 range) that has a slight fretboard hump near the neck pocket. I figured that was the culprit, so I performed a fret level under string tension. The frets are now perfectly level... yet, it continues to buzz across the entire fretboard, even with fairly high a…

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…

Yamaha FG410A with very fragile fretboard

Hello everyone, I hope you're doing good. I'm very much a new guitar repair enthusiast, any advice or feedback would really appreciated. I'm working on this Yamaha FG410A, as you can see, it's in rough shape. The guitar lived in a case in a storage container since the 90s. The guitar was really dry when I got it, so I started my slowly introducing moisture. I removed the frets and then put the guitar in a bag, with a hygrometer…

Semi-hemi fret question

For those of you who regularly do semi-hemispherical frets -- how long do you make your frets? Specifically for a bound fretboard (although I suppose this would apply to either bound or unbound) do your frets come up a little short of the outside edge of the binding? And if so, how much gap do you leave? I did my first semi-hemis on a new build and made them end flush with the outside edge of the bindings, but it doesn't feel right.…

Thanks for adding the visual. So if there weren't a chamfer there, you'd be about 0.02" inches short of the edge, right? That "feels" right to me....

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…

Any helpful tips with bar frets?

Hello, One of my commissions is coming down the pike and it's going to be my first time using bar frets. I could use a once over for any helpful tips if you have any. About the guitar: Aged HD-28 but mahogany back and sides. I think Martin called this a HD-28 M? Skipping the truss-rod and using two carbon fiber strips. My process for Frets: 1: I CNC my fingerboards to a 16" radius and for T-frets I use a .023" to cut slots with a mat…

Depending on the carbon fiber strips and the gauge of string, you're compression may be moot, or at the very least, a fairly subtle factor. I would do a lot of testing before you glue the neck on to t…

Cutting Fret Slots

I cut the fret slots for a baritone guitar build today, so I thought I'd share my method for cutting fret slots, as I think it is a bit unusual. I radius and profile my fretboard before I cut the slots. I print out a paper layout of the fretboard, double-stick tape it to the radiused and profiled fretboard, line up the saw by eye to using red hatch marks on the printout, and saw the fret slots with a 3" circular saw that rides on…

Vega Solo Lute Baritone Ukulele Neck Joint

I just pulled the neck off a Vega Arthur Godfrey Solo Lute baritone ukulele. It was pretty easy. First I heated and loosened the short fretboard extension. I already knew the neck was attached with a glued butt joint and small straight tenon. The picture show where I drilled three holes for foam cutter heaters. I only used the two on either side of the tenon, at the 16th fret (Note: neck joins body at 16th) and didn't need the hole at…

Seagull Acoustic Neck Reset...

Hey everyone, I wanted to do a bit of a follow up on a repair I'm doing. A customer brought in a Seagull acoustic guitar that had been dropped, causing the heel block to separate. I managed to get that glued back together with pleasing results, however I did need to take the neck off by removing the two bolts which thread into the heel block, and unglued the fretboard extension. All went well here, although I'm left with a situation whe…
