Getting the galley flat in should have been a problem for everyone in my view. getting the copper wire through the sides seems impossible to me, although if people can lift the flat up a bit maybe they can poke the wire through somehow. for now it is impossible to get the flat in place, or even close to. (dare I tempt to bend the plywood to get it in?) I intend to shave a bit. probably mark an eight of an inch around the sides so I can gauge how much I have taken off. I didnt get my kit from CLC US directly so maybe that chamfered piece of wood is the temp spacer.. If it is spare, treat it as such.
