Hi Tom and John. We're trying to slip the glue joint and heat the lignin in the fingerboard. Lignin is a natural glue in wood that holds the cell structure together and acts much like glue we use and w…

Gibson MK-72 Body Damage

All - looking for recommendations on overall approach for repairing this nasty side crack right at the edge of the tail block. My initial thought is that either the top or the back needs to come off in order to properly glue and clamp the main split. Thanks in advance. Images

I use a file or a sanding block. I fit the new side by pulling sandpaper (like on a neck reset) to start and then finish with a little bit of chalk and futzing. You could pull the tailblock inlay and…

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!

I mostly build flat tops and the occasional archtop. I use titebond to join tops and backs and have used the superbond to glue cocobolo in the past. I would have no objection to using the superbond…

Tool for shaving back braces

I am retopping a guitar and while it's open I want to reduce the mass of the back braces. Since the sides are in the way, I can't figure out how to cleanly cut the excess brace wood away; anything I've tried involves the handle hitting the sides and preventing a controlled, clean cut. Is there a tool - say a "pull finger plane" - that I can pull from the edge to the middle of each brace to facilitate this?

My problem in this parlor guitar is that any chisel I currently have is too long and I can’t address the middle third of the brace without coming in at such an angle that I can’t control the chisel pr…

Stelling Banjo Tailpiece

Hi all! I was wondering if anyone knew how to source a Stelling tailpiece or knew of what would fit? I have a White Star model that came in with one that's broken. I tried their website and I just get errors and I understand Geoff Stelling retired a few years back. Images

Classical Guitar Bridge Reglue

I have a Favilla Classical guitar on the bench, in for a bridge reglue. This is a low to mid-range classical guitar, made circa 1960, and it's an heirloom guitar for the customer, he basically wants it back in playing shape. The story is that he went away on vacation, and when he returned the bridge had delaminated from the top and took a fair amount of finish with it. It also appears that someone attempted to glob on superglue at some…

Les Paul Truss Rod Spacer and Nut

When taking the ends of fret tangs off how do you guarantee not to file into fret causing perceived lift when making them flush?

Hi There, I've seen a number of jigs, Some seem like they might work with specific size frets but we all know that even same sized frets have some variances depending batch and where on the line it came off the spool. No matter how i do it I seem to scrape the bottom of the fret trying to make it perfectly flush. I've considered using small rotary round burr or cylinder and only touching the tang so if it does go to deep its…

Heat Blanket controller....

HEy FOlks. Ive Been using a really old timer and reostat control, with a separate thermometer, on my heat blanket set up for a while. Its worked, but id like to be a bit more mindless about it if possible. Does anyone have suggestions for heat blanket controllers that have a digital readout and built in temp control sensor?

Sounds good. The reason I picked this model is because is can use a "K" style probe or a thermistor probe which will work in a wet environment (greenhouses etc.). I posted a flat probe upstream that…

Confounding Refret....

Well, I am pulling my hair out here... just did a compression fret job on a 2017 D18 Authentic 1939. Neck had severe excess relief, so I pulled the frets, planed the board flat, and got to work....done this a handfull of times, so I wasnt expecting anything out of the ordinary...... I got a handful of frets in, checked my relief by stringing up the guitar, and decided I need to keep pushing, so I got a full set of frets in and som…

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…
