Andrew,
its 125mm sheet with 2 x 50mm curved ribs & a series of 50x70mm long inner pieces to fix the inner lineing to.
will post a different view to make it all a bit clearer.
takes bloody ages to fabricate for something which will be hidden from view.
hay-ho.
head in a bucket for a bit more soon.
when its done, will be dragging to the NE for a jar with you.
im paying.
