Here is a series of pictures documenting the evolution of the Frankenstrat Project at the moment where I have the neck and body supplied by EG Solidbody and vibrato provided by Hantug.

I read a long time ago somewhere on a guitar forum that a test to do to check the quality of the couple body / neck was to see if the body would hold to the neck without any screw.

Test result: it holds as you can see in the picture below.
