Default Tiny gap heel-neck and body OM-42 Martin

Hello all,

Just checked my Marin OM-42 and see there is a tiny gap or place where is no glue? between de neck and body (see pictures).

Is this structurally ok?

Kind regards

As in your other thread on the same subject, https://www.acousticguitarforum.com/...=581851&page=2, as long as the neck doesn't move in its attachment, it is cosmetic.

Here is a video by Robbie O'Brien that shows one method of making a bolt-on mortise and tenon: https://www.youtube.com/watch?v=yzlZvDyKnPI


Note that any deviation from flatness of guitar sides, guitar top and/or tenon shoulders will result in a gap between the neck and the body. The gap is cosmetic and does not compromise the joint.

Hello Charles,

Thanks for your message:

This is my OM-42. I decided to check that one due to the guitar from the other post.

This one has the dovetail.

Same basic principles, dovetail, mortise and tenon or butt joint.

Looks like a not-so-clean set or reset to me. I like a clean, solid joint with no gap in the mating surfaces. That part of the dovtail joint is not normally glued at the factory, so, if there's glue in the rest of the joint, it appears to be a marginal reset.

It is a new guitar.

Got a tip that my so called glue might be polishing compound. Tomorrow Iíll check if I can take it off.

I think if it were me, I wouldnít do anything that would risk voiding the warranty. Iíd take it to a Martin Authorized Repair center and let them have a look. Iíd expect a new Martin in that price range to be perfect. Even if it doesnít affect structural integrity, it would bug me; especially if itís on the bass side where you can see it every time you play.

Default Certainly worth trying to clean up...

Might be polishing compound which you can safely clean up with alcohol, naphtha, or even just water on a cotton bud or cloth. If it wonít clean up then itís most likely glue or lacquer. It does look a little untidy and not something Iíd expect on an expensive instrument.

Looking at the photos on a desktop computer (larger)...

If one is going to be that picky about small cosmetic details - and I'm not saying that one shouldn't - the purfling on the heel cap doesn't line up with that on the body and the seam in the body binding at the heel is pretty visible. It doesn't represent the pinnacle of workmanship.

It is a question of expectation.

What does it take for you to know for sure?

Good advise from knowledgable people.

I can ask the seller: but I don't know if I get the most honest answer.

Maybe you are a luthier? If so, I would happily take your advise that it's a solid neck joint. I don't care about the looks.

I've had Collings en Santa Cruz guitars. They don't have these things. Then again I chose the Martin above them because of looks, feel and tone.

So when I am happy? If some with the right knowledge can say this joint is ok.

Yes charles is a lutheir .

The only true way of knowing if that joint is stable is having a local luthier look it over for you, we, here on the internet, can give you an opinion based on an image on a computer screen with your descriptive.

Hello Steve,

Thnx for the reply.

If you would have the guitar in your hands what would you do to check it?

FYI: Neck angle is good. Action is great and plenty saddle left.

There is normally no glue on the cheeks of a neck joint, no matter what style - dovetail, bolted or otherwise. If a dovetail, there is glue on the cheeks of the tenon only. I would say your neck joint is fine, no need to worry, but only time will tell. Ignore it until it calls out to your for some love...
