Yes, there’s no truss rod. It worked in the last build so I’m trying it with this one too There’s the fretboard section that is going on top which is another carbon fiber and aluminium sandwich, so I’m not too worried about tension issues, it’s always at the back of the mind but it should be fine I reckon.
In terms of routing, that would certainly be a lot of work No tenon, it’s just a bolt on design.
