Thing to remember : The rear of a forklift swings <out> on curves
Bearing in mind that there are fences guarding the front and sides of the forklift area, IIRC John has aready identified that there is a "danger area" along each side, and in the front corners (20mm parallel to the fences?)
In short, if you are starting from a position too close to an obstacle,
such as the fences, and your first move is to turn/back <into> the corner,
the geometry of the forklift turn system is such that you simply cannot "change direction" without the tail being locked by the fences.
(you also won't actually gain too much "angular offset" in that first move,
virtually wasting the move...)
Therefore, counter-intuitive as it is,
it is actually better to make you first move a back <away> from the side fence, to gain some elbow (or tail swing) room.
This logically puts your fork on an angle <away> from the palletracks, not <towards> it.
At this point you have 2 hoices,
1 - either continue the "doe-si-doe" moves,
and execute a 360-degree turn in 7-or-so shuffles
2 - having gained some elbow room, try to swing back towards the pallet rack,
(IE reverse your "attack sequence")
while not "backing yourself into a corner" again...
Clear as mud?
That's what will make it so "fun" at shows...
