Make a gate using 19mm T&G v-jointed timber in a ledged and braced
design, say about 8 feet high. This gives a smooth surface & will be
difficult for anyone to climb. Use two bolts on the top and bottom
ledges and fit a mortice lock on a block of wood on or just below the
centre rail. Infitted one like this about 8 years ago and despite a
comment to the contrary the lock still works.


You haven't made it clear to which comment you refer, but mine (and I
don't see any other) concerned a mortice lock fitted to a gate
fabricated out of wrought iron or (more likely) steel strip.

A mortice lock advertised to meet BS 3621 (or some lesser standard)
only meets that specification if it is installed as specified in the
standard.

In general that means **** all wrought iron (type) gates or 19 mm
timber.
