Indian Rosewood low-tuned 12 String

[Joe Sustaire]

I think it would be interesting Jesse, why don't you test it out for us?

Yeah Dennis, I'm just using my old 15' radius dish for the backs as of now. Hanns had made a 10' radius trough that he used for his backs, would like to try that at some point, just haven't got there yet...… I like curves in a guitar!

Joe,

Sandblasted top, what did I miss? I'd also like to try cylindrical tops and backs as well. Nigel Forster references historic instruments in similar fashion. I've never heard a guitar with this type of shape but I imagine the longitudinal stiffness would have a sonic affect.

Keep em coming.

Thank you sir!

Finally managed to spend a little time in the shop the last couple of days...…..

Got the back braces in and carved.

Glued the top onto the rims.

And now the back is glued on.

So if all goes right, looks like I'll have a box, hurrah!
Just a little insight into how it is working in a shop with no temp or humidity control. We've had a lot of rain lately so I'm sure the humidity level is high. As we all know, not good for gluing braces onto plates or gluing plates onto rims. I've got a loosely vented closet in my shop built from some old doors, with a small bathroom gas heater inside. So glue bottle, plates, braces, and rimset spend a couple of days in there to cook off the moisture before glue up.

You do what you gotta' do.........

The guitar is looking great as it is coming together.

Good to see you back in the shop, Joe. I was just thinking of asking you where you were at on this one. What are you doing for binding?

John

[Joe Sustaire]

Thanks for the comments guys! And I believe I'm going with tortoiseshell celluloid binding on this one since that's what I used in the soundhole, but don't hold me to that...…..

Speaking of memory...…. anyone notice anything funny about the back bracing?

Yesterday about 4 in themorning it dawned on me I didn't add a reinforcment strip on the back join..... I usually do that first, then cut out where the braces go and add them. Now I know I've seen threads about how necessary that strip is on the back since we usually don't have one on the top plate, and as I recall many think it isn't necessary and don't use one, that it's more tradition than anything. I guess now I get to decide whether to try and go back and add it through the soundhole or take the gamble that it isn't vital.

Damn, so much for memory.......

Joe, my two cents on the back reinforcing strip necessity is that it’s probably not an absolute must, especially if your glue joint is good. And if I read your posts correctly and you routed in the decorative back strip after the back was glued up, we’ll that in my mind does essentially the same thing as the interior reinforcing strip.

I think it’ll be ok.

My $0.02 would be to add one "diamond", a little 3/4"x3/4" or 1"x1" square rotated into a diamond, between each brace pair. I would probably attach the reinforcement diamonds using those damn rare earth magnets that I always swear I'll never use again just before I use them again.

You might want to do some artwork on the one diamond that will be most visible through the sound hole. Like maybe a reproduction of the Sistine Chapel (or, even better, an original Sustaire!)
