Only discovered this thread after you'd started the other thread. Here's a comment: do you see the side lamination as a means of extra support for the soundboard? I ask because you seem to have the soundboard very thoroughly braced; perhaps the braces are there for their influence on the type of response you get from the soundboard rather than reinforcement - hence the colour differentiation? If you've already explained all this, please ignore me; I haven't read everything in detail yet.

Only discovered this thread after you'd started the other thread. Here's a comment: do you see the side lamination as a means of extra support for the soundboard? I ask because you seem to have the soundboard very thoroughly braced; perhaps the braces are there for their influence on the type of response you get from the soundboard rather than reinforcement - hence the colour differentiation? If you've already explained all this, please ignore me; I haven't read everything in detail yet. Firstly the different colours to braces are just an indicator (to me) about brace construction: darker braces are to be laminated spruce/rosewood centre, lighter braces are spruce. Braces are intended to be taller/narrower around the lower bout area and the hardwood lamination will add stiffness which I can control with shaping. The tone bar at the upper bout will be heavier as well as laminated. I've rotated the tone bars to radiate out from under the bridge. Reading the Colin Symonds' Meet the maker thread acousticsoundboard.co.uk/thread/371/meet-makers-colin-symonds I like the 'A' brace arrangement around the soundhole - I've done that with two guitars so far - one classical one SS so that arrangement with the arched brace and the 'A' frame going from the X-brace to the neck block is tried and tested and will stay on this one. Re: the laminated sides - no. Essentially they're no thicker than a conventional side/kerfed lining set-up. I'm trying them on this one to see if the advantages I've read about with solid sides not absorbing energy from the top/back hold up! Time will tell on that.
