I know a man that builds mahogany necks. He laminates them with the grain on the centre piece going the opposite way to the outside ones.

Thanks.

hyunsu - have you had any problems with the screws not holding after removing the neck many times?

The only issue I really had was the screws not holding - not the stiffness of the neck.

Thanks for the info. I think I might look into some of those brass inserts.

hi.. i 'm not necessary screws .

it is enable without screws, on head angle laminate..

many people waste titebond . and clamppling more power...

that is no good method..

clamp is not press tool.. it is fixing tool..

too many press power.. titebond is go out.. and glueing is down..

and wood is laminate on press power.. that is no good...

wood is power on return prev status...

so forced laminated by clamp is not good..

sorry english is not my own language.. T_T

planning work is too important..

and laminate suitability clamp.. save your titebond ^^

too many press power on clamp is titebond go out..

bye..

so are you saying its better not to have my clamps really tight when laminating pieces of a body, neck, etc together?

It's not that I don't appreciate the info but I'm not doing any lamination at all. I have done many lamintaed necks before but this one will not be laminated. I was just wondering if any one has seen other bolt-ons made of mahogany or other soft'ish wood.

Thanks,

Dave

Hi Dave, my gothic mockingbird has a mahogany neck. I have removed it a couple of times and now the screws won't tighten anymore. I was thinking of drilling bigger holes, glueing in some hard maple dowels and drill new screw holes.

So I don't think it's a good idea to use softer woods for bolt on necks, but that's my opinion.

:D

Thanks Alex - that's exactly what I was wondering and was concerned with. Apparently, the Parker Mahogany NiteFly is a mahogany body and bolt-on mahogany neck. I don't know if they do anything special to handle this though.

Anyway, I have heard mixed reviews on using the brass inserts but I think that's what I'm planning on doing. The people who are against it just don't seem to think it's worth it but with softer woods, I have a feeling it is.

Have you heard anything about these?

I know that Fender Japan uses something like it on their high end Yngwie Malmsteen models

So what Hyunsu ia saying is if your joint is a tight fit, ie. you sand each face smooth you will wind up squeezing all the glue out when clamping. His drawing looks like you get a better bond with the joint faces roughened up to help retain the glue while clamping. Speaking of clamps, I like the ones you are using, I think I might even be able to make a couple like that. I have some 5/16" threaded rod laying around.

I liked using 1 piece mahogany for a neckthrough with a dual action (Hotrod) trussrod. I found truss rod adjusting was more responsive. Once the guitar was strung up you could adjust for relief and actually see the strings move up or down off the fretboard as you turn.

AlexVDL, I don't think the problem is with the neck because your anchor point is actually the body and not the neck. I don't see good results by simply anchoring a neck into mahogany with just wood screws. You can see how soft the wood is by attacking it with a router at slow speed (I learned my lesson there). The stuff just tears out in chunks. At best, I would drill out the neck and then tap bushings or sleeves in for bolts to slide through. The bolts would have to be a close fit for the inside diameter of the bushings to avoid wobbling. On the body side I would screw in threaded anchors that have machine threads inside. And you would need at least 4 with very close tolerance for the mating surfaces. Any gaps between the anchors and the surface of the neck pocket and you might rip them out by tightening too much.

On a side note, I find that getting a digital camera one of my first priorities for these discussions. Some things are just too hard to describe these days.

I don't know what hyunsu tried to say, but the glue itself is not that strong... a thick piece of glue is hard but can break easily (glue is brittle). The smoother the surfaces the less glue and the stronger the joint. The glue should act the same as the natural binding material for the wood fibres. By overtighten the two surfaces the glue will get soaked up by the wood, and that is exactly what you want.

Damn it's hard to explain in english, but trust me, a thick layer of glue is not the right way!

Now on the the subject please...

Southpa, I was talking about the neck itself being too soft. By removing and putting back the neck you have to untighten te screws and tighten them back. After a couple of times the screw holes in the neck get too big (which doesn't happen that quick with harder woods), so you can endlessly turn the screws without them getting tight. So I want to insert hard maple dowels in the place of the old screw holes in the neck. It doesn't have to do with the body, but with the softness of the neck itself, and it being too soft to hold screws.

can you post some pics of when you install those studs dave? i'm interested in those, it'd be great if you could give everyone an acurate description of how easy they install and if they're reallly worth it for (soft of hard) hard woods..

Yeah, you don't want your pieces to "float" on a layer of glue.

Well, I'm still confused - are you talking about laminating the neck again?

I think Alex is describing the exact problem that I was concerned with. I grabbed some brass inserts today and will probably be installing them soon. I just don't want to risk having trouble with it later.

The neck itself should be fine - I'm not worried about it warping or breaking - it's just the screw holes that can get worn out with time (from taking the neck off).

If I can get to it tonight, I should be able to take some pics. The digital camera is only at home once in a while so I don't always have the chance to take pics like I would want to.

Thanks for the replies.

sorry.. i am not use english.. so i do not expression what i want to say.. T_T

thank...

Posted

wow...that looks neat.

but i think i understood what you were saying.

i think you said "too many people waste glue because they have a poor fit and then try to make up for the poor fit by using excessive clamping pressure.a good fit and gentle clamping pressure is much better"

and i agree

thank westhemann !!!.

it is my wite message.. thank... thank...

i will make mahogany neck.. my new guitar.

westhemann successfully done your new guitar.. good luck..

bye..

screws are not needed

many people use too much glue and clamp too tight

that is not good

clamps are not for pressing,they are for fixing items in place

too much pressure will sqeeze out the glue and make it weaker

that is what i think you said...am i right?

the only part i don't agree with is the part about squeezing out the glue making it weaker...from what i understand titebond needs only a very thin amount to bond effectively,and you can't sqeeze it all out...some will always stay...but anyway i am sure you know what you are talking about...your guitars are beautiful

i look forward to all your posts

thank you westhemann.

i unserstand your mean ^^

i'm not skill english ... so i include pic..

Wes, with a well fitted joint overtightening can actually starve the joint, by forcing *all* the glue out, or enough that you can compromise the strength of the final product. It's a bit of a balencing act - too much glue, weak joint.... too little... weak joint!
