It's amost two years now since I first experimented arching the soprano backs with my Acme back bender...Since then every soprano I've built has this method applied..and it has been a 100% success ...no need for a gobar deck or radius dish, just spring clamps..no need for high bracing to support the arch and no flat spots just a uniformed dome shape giving maximum strength with no stress.
