Bridge Reglue Suggestions...

Hey everyone, I had a question on how to approach this bridge reglue. It's from a 1940's Kay type guitar, I removed the bridge without issue, and did some surfacing of the underside of it, but there's a problem. The bridge is missing material on the outer edges and I don't think I can remove much more material without compromising the overall shape and structure of it. I was wondering if you had suggestions on how to approach this? I wa…

Unfortunately it's an absence of material on the bass and treble sides. @member

D28 blowout

Hi all, I'd like to get some input on how to address this top blowout. For starters I own this, I got it as a project guitar, 71 D28. I'm not as experienced with acoustics as electrics and this is a big project but I got it to learn new skills and I'm confident I can do it with guidance. It had been stored in the case for many years under tension and was way too humidified. The bridge had pulled up I assume in stages. The center seam se…

Martin DX 175th bridge reglue

I have a martin DX 175TH that is in for a bridge lifting. I did some research and it has an HPL top and a rosewood bridge. I have some gluboost gel on hand but I was wondering if anyone has a better suggestion.

Here are a few tips for reglueing a bridge to HPL: 1. Clean off any old cyanoacrylate (CA) residue on the soundboard using "Super Solvent" or a similar product designed to remove cured cyanoacrylate. 2.…

Non-CNC cauls for Stew-Mac sound hole clamps

I don’t have CNC capabilities so I could not duplicate Dave Slimmer’s version ( https://loothgroup.com/loothprint/bridge-clamping-cauls/). Got a 12x18x1/2 inch HDPE cutting board on Amazon for under $10 (https://www.amazon.com/dp/B001D3LQVA), drilled a row of 1/2 holes about 5/16” deep with a Forstner, cut the HDPE into 5 sided chunks so I could orient by touch, and free handed the brace grooves on the band saw. The clamp swivel pads are 1…

Yeah, I think the current concerns with microplastics is impacting cutting board prices.

When do you guys suggest a bridge re-glue?

At what point do you tell a customer that their acoustic instrument needs a bridge reglue? Do you do it when the corners are just barely starting to lift? Once it has begun to affect playability/tuning stability? Do you offer half-measures to save them money when the damage is not too bad (dripping in some thinned tite bond instead of removing the bridge entirely for example)? I ask this because a Godin acoustic bass just came across my…

You've had better luck than me with half measures. I'm not sure why you're diluted Titebond worked, but the one of the unfortunate things about Titebond, is that you cant glue TB to TB. It could be th…

neck reset acoustic guitar with two necks (harp guitar)

I've owned this Jersey City made 12-string/drone 'harp' guitar for a few years and want to get on the repair. I've taken the necks off many dozens of Schmidt-made guitars but never one with two necks. I've searched the web looking for harp guitar neck removal and didn't find anything of use. Asking for any tips/aids/experience from the loothers. My plan is to make a custom neck removal jig that fits the necks, and then drill the typical…

Beautiful guitar. Will your neck jig(s) bind the two necks together top and bottom, as well as push up equally on the heels while you release the joints? Seems like any loss of rigid coupling between…

Appraisals

Friend brought his "old guitar in the basement" over for me to have a look at. Long story short, it's a 1945 D-18, it's all original and it's a beauty. He had no idea. I explained to him that it was worth somewhere between 15 and 25 thousand bucks, that it needed some fairly routine repairs and that he should get - among other things - an insurance rider and take a little more care of the guitar than he has been. Picture attached for fu…

The VG price guide is a pretty good place to start. On something like that, I'd be tempted to pay for an appraisal from Gruhn's though. They used to do email appraisals that were reasonably priced. Re…

Tremolo issues. Not returning to "zero"

Hey guys. I guess this is an old topic, everyone talks about it but I haven't been able to find a definitive solution for this. Here's the deal: I'm working on a PRS Silversky that has this old problem that when you use the trem bar, one string (G in this case) goes sharp. I made a few adjustments to the nut as we all know that's the first thing to look at...no good. This guitar is new so I'm pretty much ruling out the bridge and posts si…

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…

DIY silicone blanket heater

Thought fellow looths might enjoy this geekery. I've often wished for custom size heating blankets, but didn't even try uploading the file to get a quote from some of the major manufacturers. I was looking to spend countless hours of my life on something and save a hundred bucks. So I did some research, a little bit of head scratching, a slight bit of math reckoning, and made this '70s Martin bridge plate remover. Pretty slick, nice…

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…

Fender, Schmender

Since most of us fix or make guitars, we have probably heard something about the cease and desist letters Fender has sent out concerning the Stratocaster. I thought I would offer some thoughts. As always, caveat emptor. There are three basic ways to protect intellectual property under Federal law. Patent, trademark, and copyright. Each protects different things, and has different underlying legal theories. Lets begin with pate…

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…

54' SJ-200 Bridge replacement....

Well, I have exhausted all the internet can offer for options for a replacement bridge. The customer, long ago, removed a ton of material from the bottom(!!!!) of the bridge, and now that ive taken this guitar on as a restoration, its up to me to make a new bridge. I have found some ultra small pattern bits, and round-over bits to do the inside of the mustache flush, but I can not for the life of me decided how im going to cut the bulk…

Intonation: Ive never seen this

I'm restoring an old parlor guitar. I have just discovered that it plays 20 cents sharp. Thats not in and of itself a mystery, usually. This guitar however has exactly the same distance from the nut to the 12th fret, and from the 12th fret to the "saddle" which is now a small shim under the two E strings both are 12 3/32"...with room in front of the bridge pins to finesse the location of the saddle slot, which I have not routed yet) I s…

So what about Re-tops then…. (on a vintage D-35)

Hello again folks, how is everyone! So I'm curious about what people here think about re-tops, who's done them, and what sorta ballpark rates you've charged for past completed jobs. I've got a bit of a wild one here, so strap in if you've got a couple minutes for story time! Back in 2012, I traded an HD28V of mine for a cool 1966 D-35 that needed some work. Basically, the body and neck of the guitar were fine apart from…
