Shaping Back Braces

Here's the back off the go-bar bench with it's braces shaped (using the worlds smallest plane), tape off and all bonnie.
A wee note about the back.
I only curve the back one way (across the grain). When I first started building guitars the idea of doming the back as dramatically as a Martin or Gibson seemed a little like asking for trouble, what with all that pressure on the glue joints from putting the back plates under so much tension. So I started doing it like this, I soon found out that I'm not alone in this technique, there are other builders such as Stefan Sobell (who really was the first I think).
Anyway, everyone with a Martin or a Gibson, PLEASE, don't worry! The way they put there backs on is fine, tried and test for many years! I use this technique because it works for me and my instruments, you see I think a back put on this way makes a guitar sound different.
