Default spider cancer

Hi folks,
In our area we say: "the cat cannot stop chasing mice"
I suppose you perhaps would say: "A leopard doesn't change its spots".
A new spider with different woods and some acessory details and a lot of fun during the building procedure.
As wood Tobias Traub ( https://www.oroboruscustoms.com/ ) and I have choosen a nice sinker cedar as soundboard, a yew as back and a dummyback with katalox.







It's always breathtaking to imagine the closed box with this woodcombination.
Looking forward to the next steps and hope you will enjoy the thread.

Default spider cancer bracing

hi folks,

meanwhile the soundboardbracing is ready and I'm still looking forward to the next steps. Honestly I have to say that it seems to be a long time to play it first time on the holy grail guitarshow in Berlin, the end of the trail.





all the best

That Spider is a wild design! Iím not sure what a dummy back is. Is the Katalox going to be an outside laminate?
Congratulations on your build!

Mark

Default spider cancer dummy back

dear Mark,

thank you for your friendly comment.
In my knowledge the yew is a very thin, responsive inner back with the bracing, you have seen in the further pics, which needs some shelter for the outer stress. Therefor Tobias uses an outer back as shelter, the dummy-back, here with katalox, that receives an own bracing and an own lining to bring the connection to the sides. It's not laminated to make it more stiff, it's more the opposite to let it swing. (I hope my english is good enough to explain it.)
This dummy-back needs a lot of soundholes to bring this responsive effect out.
This build will be the sister to my spider scorpion with some nice features and I was very impressed of the result of this construction and I'm really looking forward to the new one.
I suppose the next steps and pics will demonstrate the construction.

all the best

Default the dummy back

Hi folks,

it seems to go on and meanwhile the back is clued in und the lining for the second (dummy-back) is prepared.
Looking forward to the closed soundbox.

I have to say it is all looking great, but I am still confused on the back. Is there a space between the yew and the Katalox then with holes drilled into that space
and if so to do what?

Thanks.

Default dummy back

Dear Tom,

the luthier, Tobias Traub wanted to create a guitar with a responsive back, So he produced it very thin back with it's own bracing but he made the experience that it was too vulnerable to mechanical force. So he decided to lay a second back over it with it's own bracing and it's own lining. But the result of that responsive box has nearly disappeared with htis "dummy-back". So he tried to cut some soundholes in that second back and the soundbox brought a quite clearer and stringer voice than without these backs.
This new buidling has an older brother, the spider scorpion and perhaps -if you like- you can hear it on the thread about this guitar.

I honestly would like to present it on your guitarapolooza but from good old germany it's a quite longer way than to "Tipperary". So I hope I could explain it clear enough with my german english.
By the way what does it mean "guitarapolooza" ?

all the best

Kind of like the 'Virizi Tone Producer' that Gibson used in the early thirties on some of their instruments. An interesting idea, I wonder what it would do if the sound holes were in the rear upper bout of the side, rather than the back - that way they could act as soundports.
