Hi Dean,

Yes, its been too long, tbh got a little too inwardly focussed and last 6 mo or so I've struggled with just coping day to day, but trying to get up n running again.

Well if I had some tools and some hands to use them I probably could... but my tools are still in storage and I couldn't use them anyway. Anyway, I think the way to do this would be to cut them out with a plasma or laser cutter to get neat radiussed corners (failing that, tinsnips and a file ), do the surface preparation (not sure what exactly, want a brushed, stainless finish) then score the back and fold using some 6mm mdf say as a former.
