Looks superb so far Peter, how thick did the double top finish out and what kind of appointments do you and your client have in mind?

Make sure you post some more images as you go.

Cheers

Kim

Peter, that looks great. Based on some passed experience with double tops I'm thinking I don't need to brace them quite a heavy as a standard top. I have a very lightly braced Koa double top ready for finishing I let you know how that comes out.
You'll have to let us know how it sounds.

Thanks Jim!
I did brace it pretty light, not as light as I wanted too but I had to take in consideration the new owner plays mostly heavy percussive strumming... gotta make sure the top doesn't get overdriven...and stays together!

Peter, i forgot to mention 2 things;

1) this is a commish right? well that customer must be really excited seeing this guitar coming together!

2)Make sure to let us know how this one sounds!

Keep on going my friend!

Looks great Peter!

I am curious, what is the purpose or intended result of a double top? I have seen double top classicals with Nomex honeycomb interior sandwiched between the top and bottom layers.
But I suspect since your using a standard bracing pattern that this is not what you have done?

Beautiful Guitar Peter, I love that wood combo. Ya know it would be great to hear a sound sample of your double top when it's completed.

Peter,

That's very cool. What thickness did you make the 2 parts of the top? What kind of glue did you use to attach them together?

Thanks,

Lance, I took a different approach to this double top construction. I used the same priciple as normally done with nomex but only used 2 tops and skipped the nomex!
I mapped the bottom top with all the bracing positioning and bridge patch, etc... and drilled the other areas honeycomb style creating a hollow area on the selected areas. In essence I have a same thickness double top but lighter and partly hollow...
Its tap tone is pretty "boomy" so I'm excited to see (hear) and it'll turn out!

Thanks guys!

Peter,
On the other forum I've had a few people volunteer that they don't like how dark the sinker redwood is. I tell them that I do and it is really a personal preference thing.
But, it has got me thinking about this system. Do you think it makes a difference in sound which wood is up? The thought of having the warmth and bass of cedar and the dent resistance of sitka with the sitka on top is rather appealing.
What do you think?

Steve, I really don't know... I picked Englemann for the bottom just in case it also did make a diference... I'm sure both woods HAVE to make some tonal differences but unless I make a few different combination double tops I'll never find out!!

I do like your idea.... The strength of spruce combined with the tone of cedar!

Okay, time for some educating..... How is a double top different than a laminated top on a low end guitar?

Good question Lillian. I need some answers too!

Looks great Peter. Did you have any trouble bending the camatillo?

Do you have any pics of the drilled out areas of the top before joining
them together?

Mike

Well, first off the laminated tops are made of cheap laminated ply woods that are offen cross grained layers topped with a wood veneer... whatever they decide, mostly spruce.
A double top is a bit different. 2 or even 3 real tonewood tops are used and then one of them is hollowed out and the empty area is filled with Nomex (a honeycomb very ligth and strong material) so the tops retain their strength but become lighter and more flexible.
In my particular case I only drilled the area in a honeycomb style creating a hollow area on selected areas. The top was left at about .115 as a regular top.
I only hollowed out the lower bout area in an attempt to try to affect the vibrating areas.

Thanks Mike, the Camatillo was a dream to bend. Better that EIR. but a lot heavier. I like it!
I do have some pics....will post later.
