kominak -> Tentellones and titebond (Jul. 27 2016 10:28:11)

Hello,
In the past I used solid linings, but I'd like to try tentellones in my future build.
I want to ask - is it possible to glue tentellones with titebond, since there's no way to clamp the joint?
I understand traditionally it's done with hot hide glue due to its "self clamping" properties.
Would the joint glued with titebond hold?

Thanks!
Martin

yup. No problem at all. I've done it for coming on 200 guitars.

Thanks a lot, Stephen - that's good news.

Can I ask why you want to change to Tentellones when a solid lining seems to project sound back into the top rather than lose some of its power into the sides of the guitar?

I used kerfed lining for years and only found this effective technique when I started building the Miguel Rodriguez classical guitar with its 2 part solid laminate lining for the top function.

This technique raises the frequency and clarity a little and projects tone back into the top for better projection, IMHO.

Could always leave out the spaces between the tentellones. I read one luthier say he adjusts the spacing as one ingredient to get the sound he wants.

So how long do you have to hold the tentellone in place before you can release it?

Tom,
I'd like to try something different, I guess. The guitar I built with solid lining seem to project very good and is noticeably louder compared to similar guitars - but that may be only my feeling and solid lining may be only a part of the reason.
I have a feeling that the tone is "too clean" for my taste and that by using solid lining I'm loosing some of the character I associate with flamenco guitars (similar to using stiffer sides).
Keep in mind please that all of this is pure speculation on my part and I have no data nor enough experience to back it up :)

I understand your ideas to want to experiment with it.

All of us have to experiment to settle the ideals in our head.

Please let us know what you find out with the change over to (single) tentellones.

Assuming the sides and top are held tightly in place you don't need to hold the tentellone at all, just place it and wait for the glue to dry. If you use a solera to dome the top you should put a slight bevel on the tentellone so it mates to the top properly. I've found a 2 degree bevel works well with our guitars.

Just used to hearing from the glue people they want a certain clamping force on the mating parts. Having the right bevel seems like an important detail. I would guess because of the greater area of wood back and sides as compared to the tentellone the moisture gets sucked out of the glue and the tentellone gets snugged up. Will have to try it on a build one day. Lately have not been bothering with a mold.

The trickiest part about tentellones is getting them to not tip away from the side. If you achieve that then almost any glue will work. I do hold mine for about 15 seconds (maybe just superstition [:D]).
On my solera it usually works fine if the tentellone's back and bottom are perfectly square. But occasionally I've had to bevel some slightly to stay snug.
