The 1.2m section is back supported and may have a little support from the
appliances below. The granite is 30mm thick, rather than 20mm, so should
be
a little stronger.

However, a little birdie has told me that 1.2m may be too much anyway.
Apparently, I must put a 40mm front batten on too. I wonder if I'll get away
with a 30mm plywood flat panel instead. I haven't drilled the holes for the
door hinges yet, so I can probably get away with dropping the appliances
around this much. Any more and I run out of height.

Christian.
