cheers guys, i have slapped myself on the back already, perhaps too much, and making blunders like the neck pocket slaps you back to reality! the plan with the block is, two screws will go through that into the neck, another two through the body into the neck and two just into the body. hopefully that many screws will clamp the neck in place against the plate and should be bloody tight.
gibson headstock would look good , but such a curved and gothic style body needs a special headstock... and here it is.
