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…

One other issue with the guitar that I wanted to mention was a fairly sizeable split in the back. At its widest, there is a gap of about .015" and I'm curious to know how you all would handle this? I…

Wood Storage

To the builders out there, how/where do you store wood for builds? Is it different for back+sides vs tops vs neck blanks? Any periodic maintenance required? Thanks in advance!

Can't access truss rod

I bought a boutique guitar, used from Guitar Center. I really want to like this guitar. I just got it a couple of days ago. Looking forward to doing a setup. The neck is straight. I went to add some relief and found that the wood around the truss rod keeps the 4mm hex key from engaging. Any suggestions on how to hog out enough wood to get access? I was thinking of superglueing some 180 sand paper to a 4.5 mm hex key and sanding the…

If I really liked it (or it was a client's guitar) - I might go fearless with a drill bit on a low setting to remove some material for access.

Early 80’s Jazz Bass Fingerboard Separation— Bi-Flex? Washer issue?

This jazz bass has come in with a cracked and separated fingerboard near the nut. I believe this is an early Bi-Flex but am not entirely sure or familiar with them. The truss rod is functional and tightens up when turned. Top of the walnut plug is missing and the washer appears to be crooked or dislodged. Not sure what purpose that washer serves. This is probably the thinnest bass neck I’ve ever seen and it’s no wonder that this fingerb…

Good call Ian, I can definitely get strings on there. I suspect it won’t do well under tension. It’s incredibly thin, neck has pretty much a shallow v profile. Hardly any fingerboard too. Might need a…

Humidity stability, moisture meters

It's that time of the year when I start to get all paranoid on the humidity levels of my shop. It happens at this time as the heating seems to send my hygrometers out of whack and it's quite difficult to keep things stable. So far i've been relying on keeping a 45% constant humidity in an automated system I built on Domoticz (similar to Home Assistant), which control a humidifier and dehumidifier. I'm not that confident i got this nailed…

Thanks both for your replies. In all honesty so far I have not had any issues with my builds. The Trevor Gore books do mention that gluing should always be done at 45%RH, so i'll keep trying to stick t…

Using Maple for Back Inside Center Seam

I just read a small note in a new OM plan (GenOne) I'm using that suggested maple as an alternate wood for the inside center strip between the back braces. Wondering what would be the downside of that (passive back). A curly maple strip would certainly be attractive, and the mass/ stiffness difference is virtually negligible for a passive back. Thoughts? I'm cutting braces this week...

Flat sawn maple is what all the old Gibsons used for a center strip from the 1920's to the 1970's at least. They are something like .900in wide and .040in thick. It had to have been offcuts of their m…

Taylor 310 Top Crack, Finish Delaminating

So this 310 came into the shop and had a pretty gnarly crack that splinters some toward the lower left bout. Going to do a crack repair with the TJ Thompson crack corrector and some hide glue. The issue I'm inquiring about is the finish is delaminating around the area. I'm curious as to what type of finish it is. Seems a bit flexible and spongy to be a nitro alone. There's shards of finish missing, and dirt has found its way underneath…

Comfortable sanding block

One of the first things I made with my 3D printer was this small sanding block with a ball handle that fits my palm. I was inspired by the little L-N squirrel tail block plane that my father gave me. I have neuropathy in my fingers, on top of arthritis, and it's uncomfortable for me to hold the little blocks of wood that I used before. I was surprised how well this works, and these two tools are always within arm's reach.

Acoustic Guitar Neck Repair

Hi Everyone, I was given this guitar to harvest parts from and then throw into a fire due to a partial break in the neck. When I pull the neck to close the break the action is perfect so I'd like to fix it and then donate it. Can anyone show me what clamps to use to keep it closed after I glue it? Also, would you recommend strait wood glue or would you water it down somewhat to allow it to seep in further? Thanks in advance!

What kind of cauls do you have at your disposal ? I would thing a radiused sanding block and an F-Clamp would get this back together readily. As far as the glue, you could start with watered down Tite…

Testing Mandolin Top Wood Billets

For my current mandolin build, I set out to answer 2 questions: 1. Whether to use physical deflection or frequency analysis to measure stiffness, and 2. How well can I measure wood quality in rough sawn form? (T. Gore says it needs to be planed smooth and rectangular for frequency analysis.) I have 4 different topwood species available for my current build: California Sitka, Englemann, Lutz, and Coastal Redwood. The billets range from 37…

Warped x-brace on Gibson L-3

I watched the Guild F-20 video (https://dev2.loothgroup.com/groups/repair-and-restoration/forum/topic/cracker-x-braces-on-guild-f20/#post-60310) with great interest since I've been working on a Gibson L-3 with a similar problem. A little back story - The original repair request was to address a small pickguard crack on the sound hole side. After peeking inside, I saw 5 loose brace ends on the treble side. Still a pretty standard repair…

Traditional woodworker's bench

I've been building up my "2 car garage shop" for about 10 years preparing for retirement from health care. This spring I finally quit punching the time clock. Over the same time I've build 13 mandolins and 4 guitars. Now I pretty much have all my tools in place and enough wood stored to build for quite some time. My work benches are built with a heavy door for a top and base cabinets I scavenged from work. Lately I have toyed with the i…

Fender Tele Deeper Black Colour?

Hey all! Anyone know what lacquer pigment might better match the deep black colour of this tele body? It’s an American tele deluxe with a nitro finish. Photos show: Finish damage was the size of a quarter. I’ve filled and levelled the area and sprayed on coat of Oxford black nitro. I poured a puddle of naphtha on to check the match and unfortunately no dice. I’ve used Oxford black many times for overspray during repairs and have always fo…

Epiphone LP Limited Edition severe fall damage

Okay gang I have a doozy of a crack repair. Young guy brought in a Epiphone LP Limited Ed. He had picked up the case while it was unlatched at the guitar took a nasty tumble. Severe finish damage, and the wood has a shear split in it as well. The undercoat is thick with a thin layer of nitro color on top. Spoke with a sweetwater rep and they said that the finish was nitro. Here's the guitar specs via Zsounds: Epiphone Inspired by Gibson…

Thoughts on Saddle and Bridge Heights During a Reset?

Hey all, I’m curious to know people’s general thoughts on the appropriate or ideal saddle height after a reset. And, when to replace a bridge that’s been shaved down. I know there are a lot of factors (for me anyhow) and this question could open a whole can of worms when it comes to the specifics of the guitar, its age, style of bridge and desired sound. I’m providing an example I encountered recently, but would also like to know people…
