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…

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…

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…

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…

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…

1930 Gibson L-0 Top Sink

Hey All! I hope everyone has been loothing and living as well as possible. I'm checking in to ask for an opinion. I have been asked to fix or improve some top sinking/splitting of a Mahogany top 1930ish L-0 that sits between the bridge and the junction of the X-brace. It's showing signs of wanting to crack further but neither seems to be all the way through the top. I have removed the bridge plate cleanly and have tried wetting the…

Possible ground loop in Tele

Hello all, got a problem in a telecaster I rewired that has me in a twist. The basics: friend has a 2001 US Standard telecaster (left handed not that it matters). He bought it used and says it was quiet initially. A few years back he grabbed the pickups out of it and moved them to a new tele body with a torrefied maple neck he preferred. Recently he upgraded the new build with a Lollar CC tele set, and asked me to reinstall the original…

Harmony H167 Neck Reset...

Hey everyone, recently I've been getting more requests for neck resets from customers, and up until this point I haven't been offering them since I don't have the practical experience. I'm keen to change this, and I've borrowed my fathers Harmony H167 that has seen better days. I've done an initial cleaning and assessment, the truss rod works although I may need to force it into a backbow to have a fully adjustable neck. This shouldn't…

Also you have to take into account how much flex the top has. If you could set the neck dry then clamp it and string it up you can start the calculations about how much you to take off of the heal. In…

Is this hollow body guitar worth fixing - sunken top…

I recently picked up a used custom guitar that the seller said he bought in Vietnam Nam many years ago. I bought it as a wall hanger due to the wonderful Mother of Pearl work, especially on the back. It was very apparent that the top on this instrument was sunken at least 3/8 of an inch, as the weird bridge setup was heightened to the max and there was barely any action height. Once I took it apart and removed the foam inside, I was…

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,…

Ken Parker finishing with the Bridge on

Just wondering, anyone doing Ken Parker finishing on an acoustic with the bridge glued on? I've been using the finish for a while but I'd like to start glueing the bridge on before I finish so I can acoustic test everything in its final state. I can't see a reason why I couldn't wipe the epoxy and oil up into the bridge joint and then remove it by rubbing but I was wondering if anyone has done it already. It would mean finishing the…

reality check - bridge repair - Epiphone PRO-1 Plus VS

I got this guitar for free hoping to further my skills and experience in guitar repair. I removed the bridge. its not in good shape and I don't think I can glue it back together with any hope of it holding tension again. I haven't been able to find a replacement that is of the same shape and dimensions. Epiphone/Gibson is no help. The top of this guitar is not at all flat. I don't know if I should try to flatten it before attempting to…

Questions on Classical guitar action

I am working on a wall hanger that I thought would be fun to get working. It is an old Tokai. I have repaired a crack on left tuning arm. Also removed the bridge that had been badly glued on by previous owner. I am deciding if I want to put the effort into re-fretting it. I am new to Classical guitar actions, so my question is this - when you put a straight edge on the neck, where should it hit the bridge, if at all? I have learn…
