Luthier and Instructor, Robert O'Brien, along with luthier Alan Dunwell, shows how to construct a double top or composite top guitar soundboard. Part two of two.
Congratulations. I'm at the beginning and the idea of glue transfer impressed me, and I think it is of great use to me even though I use another vacuum system. Vacuum bags also use my wife, they store the clothes to win space.
Thank you for the great content!!!! Helpful if you post link(s) in the description to all parts of a series when there is more than one part. (Maybe I missed it)
I'd always wondered how and why about double tops. Our guitar strings only have the energy they have. Managing weight on our bridges and tops is key to converting string energy to sound. Great demonstration and explanation.
Today is the day. Nomex received last week, Adi Spruce master grade for top most piece, adi spruce for cutout, and maple thin film for bottom piece. Side note: I retrieved the bottom piece of maple from an old Harmony that I deconstructed. Separated the body and neck, filled the cavity of the body with hot H2o, the laminate layers separated and the middle layer is perfect. Dried it flat and voila! Very thin film. Can't wait to string it up!
ola .Você saberia me dizer onde posso encontrar a planta em 3D de um ukulele tenor ? eu gostaria de usinar um molde e faze lo de fibra d carbono .Valeu
OBrienGuitars consegui com um amigo q faz usinagem um projeto do uk tenor em 3D . essa semana vai ser usinado o plug . eu trabalho com construção náutica , estou fazendo o uk por curiosidade e poder ter a satisfação d fazer algo q possa produzir musica ou algum som . terias ideia qual a espessura q teria q ter o corpo e tampo pra tirar um som agradável ?Se eu for fazer d acordo com meu conhecimento em náutica ,a espessura do corpo e tampo ficaria em menos d 1mm e braço talvez 1,5mm daria estrutura suficiente pra ser mais forte q madeira.
There are many commercially made bags available. A quick google search brings up many. Just find the size you like and the thickness you like. basically anything will work.
OBrienGuitars I was afraid it was some kind of high tech luthier equipment, so if these common vacuum storage bags work it becomes a lot easier! Thanks for the assistance and for keeping my favorite channel on CZcams!
certo . estou fazendo um molde e um violão jumbo pra tirar um corpo de fibra de carbono sou amador estou fazendo apenas por gosto próprio e pensei em colocar um tampo desses ,trabalho na área d construção nautica
Many thanks for the two videos! Much appreciated!
Wow - what an intricate process! Very interesting though. Thanks for providing such detailed information Robert.

Mesmo não sendo um luthier, gosto muito de assistir aos teus vídeos. Obrigado!
+Antonio Mattana Muito obrigado.
Wow! No wonder double top guitars tend to cost more. I own one. It's the sustain that really sticks to me.
hi, from where to buy the nomex please? and what is the ultimate thickness to be used in a floating bridge oud?
+Michael Onsy You can get the Nomex at www.lmii.com The final thickness for Ouds is up to you.
+OBrienGuitars thanks a lot :)

em 3D não estou sabendo mas tem plantas normais de uke de monte na internet. Parece interesante a sua ideia,

Josi e renato guedes Faz tempo que não fabrico um uke mas é bem próximo as medidas de cavaco.
What kind of vacuum bag can I use?

Would it be possible to use weight instead of vacuum press? That would make the whole project doable for me.
I would use a vacuum bag made for doing veneers and other glue ups.
Part one for those looking

ola .Realmente tem um som melhor este tampo duplo ??
Depende da sua definiação de melhor. Parece que tem mais volume mas acho que os tampos duplos faltam um som tradicional.
certo .
