Thanks all, that's really helpful. We'll have a look again at the fuse holder attachment. A couple of screws and clamp sound like a better solution. Perhaps a bit keen to get finished! I think shaving off a bit more chopping board (Boyes finest, choice of white, blue, yellow or green and the thinnest we could find anywhere at £4 if anyone is interested! Do they have Boyes in other parts of the country or is it a northern thing?) in favour of some velcro would be a worth while trade off. As for the planning, it was more of an 'evolve as we went along' approach!
