Martin D-35 with cracks everywhere!

Hello looths! Long time lurker, first time poster here all the way from New Zealand. I have recently acquired this 2008 Martin D-35 for a very cheap price ($1000 NZD - around 600 US!) it's dried out in a very cold environment and has two substantial cracks running all the way across the top, one large side crack, and a previous side crack repair that's been done quite poorly. I'm only about 3 years in to this repair journey and this is d…

I thought I might add an outlier of an opinion here. I understand the temptation to close the cracks with higher humidity, but you're asking a lot of adhesives, reinforcements and human attention span…

Thoughts on Restauration Roger Archtop

Hey everybody, I should restore this Roger Rossmeissl Archtop. There is a lot of work to do. The owner is aware of the possibly-much-more-work-than-value situation. I am still thinking about how to aproach it, I want to start working on the guitar in August. It seems that there is not much warping in the top, few wood is lost. I do not know what happened to the guitar, but sometimes I hear a voice coming out the corner of my workshop mumb…

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…

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…

Dunable Yeti with a backwards rod???

Hello! Im working on a repair for a cutsom build for a customer. Its a Dunable Yeti built in 2022. Anyway, all work was going fine till testing the rod... i discovered that the rod is working the opposite of how it should function on any other guitar. CCW is tightening (and no, no a dual action rod) Tightening this rod is adding relief. The guitar already had too much when disengaged. Trying to figure out how to approach this as this is a f…

It could be that the rod is really high on the center mass of the neck. This will produce this effect in extreme examples. This should be considered a probable defect. Are you able to set it somewhat…

which frets for LP Delixe 70s

Hi, I am still a little confused by the new look of the forum, hope this is the right place to ask. Which fretwire would you recommend for a refret of this 70s LP? The current frets are 2.75mm wide, but dressed down to 0,35mm height. I have heard storys about frets that are this low but never seen in real life before :-) (0.108" wide and 0.014" height). Thank you in advance :-)

1930s Martin 00: Best practice

Long story short, customer want to add carbon fiber in the neck for strength. Without string tension, the neck is dead straight; with strings, it's about double the relief he'd like. Is it insane to add carbon to this guitar? Or is it fine?

PBass has been stripped of it finish… looking for expertise, friends!

Hi friends, I just stumbled upon a 1966 P-Bass, nearly completely original. The owner bought it in 1971 and it had already been stripped of its original finish. That was a thing back then. You can guess that 55 years of gigging had the wood absorb much of the owner’s DNA and sweat. Maybe a few beers as well. Surface was quite tacky as you can expect. I cleaned it with naphta and StewMac’c brand-new cleaner (quite a great product I'd say…

Cheap-ish Brace Wood Source

https://www.aircraftspruce.com/catalog/wppages/bargainbag_spruce.php The air craft industry uses 1/4 sawn sitka and this is a box of their "Scrap wood" that is a good value to have on hand, (usually like 36 in long and various width) imo if anyone is in need. It's an odd ball source, but just spreading info. Be well.

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…

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…

Bass Neck Stiffness, Can't Get Enough Relief

Hello, I hope everyone is having a great 4th of July weekend so far. I was recently asked by a friend to work on a cheap S101 bass someone had given to him. It had no electronics and it was severally back bowed. After finishing up the electronics, I did the set up. He wanted the guitar tuned low, to Drop C. So, I went out and bought some Ernie Ball Power Slinkies 55-110. Once I got to the nut depth check, it was clear there were large, g…
