This is my second RS build and I've tried to get as close as I can to the original in materials and all the little details so often missed when a luthier decides they can build it better , I did this the first time.
I'll start with the X-rays of the original

There is so much information here.
It is well known that the original body was built from what is termed "blockboard" which is basically scraps of pine sandwiched between to layers of thin ply with a total thickness of 3/4" . The body is made of two layers of this hollowed and joined , and a thin veneer of mahogany glued over the top.
However , the x-rays to me didn't show the type of board that is used today. It has fine contrasting lines that are consistent in width and parrallel.
I interpreted this as perhaps ply on edge as seen in this type of blockboard
I have since changed my mind a little and it is possibly 2-3mm wide stripes glued together .
As I couldn't buy any I decided to make my own which lead to a slightly different approach but one that will end in the same final product.
I cut up a lot of ply and glued it together to form the body material


Here I've added one layer of ply , and to the other layer of ply I added a thin layer of mahogany that will become the top and back faces

With routing templates made the top and bottom layers were shaped .



You can see the Oak insert that runs down the majority of the bottom layer , the neck will sit on top of this .
the top layer has a small oak block which houses the retaining block for the tremelo


and the trem in place , this is permanently glued in.

And the trem unit itself

I'll stop there and continue later for should there be any questions so far .
