Thanks folks,

Here are the external cross overs, I am not happy with the boxes so am going to re make them this weekend, very hard to achieve perfect mitres so will try through the table saw or a router to see if that gives better results.
The tops will sit inside the rebate and are made of 3.1mm copper.

Many Thanks to Nick Gorham for his help with these.
