I have managed to put the steel string sound box together, the whole process went fine after doing just one dummy run. When doing this kind of thing dummy-runs are very important.
These heavy duty rubber bands are an excellent method of holding down the back while it dries. After spending the whole night like this here is the sound box completed.
It now requires trimming the front and back to the shape of the sides and then routing around the edges for the binding, I am going to use holly binding again, I think the contrast between the rosewood and holly will really bring this guitar to life. I need to get more work done on the classical guitar next.
A point to bear in mind here is that I do not use a mold to set the shape of the guitar. The shape of this guitar is governed by how accurately I bend the sides, so in effect all the guitars I make are unique when it comes to shape.
