To convert your Professional machine for Hockey use, lay the machine
on the floor on it lid. Unbolt the bottom half of the ball joint
clamp by removing the ball joint handwheel/spindle assembly and
the two M8 socket head cap screws with the Allen key provided. You
can now remove the clamp and the ball joint/tripod head assembly.
The Hockey bracket bolts on to the top half of the ball clamp with
the two shorter M8 cap screws and the M10 cap screw provided (see
diagram below). Having tightened these three fastenings the machine
can be turned back right-side-up and set down with the Hockey bracket
flat on the floor.
Moulded BOLA 5oz polyurethane practice balls are available
in red or yellow. The BOLA balls are dimpled like golf balls
for stability in flight and accuracy. They have similar bounce characteristics
to a cricket ball with a slightly softer case to minimise bat damage.
A 3oz Hi-Viz orange ball is also available. They have been designed
to give higher bounce to enable players to practice back foot shots
at reduced ball speeds. They are excellent for hooking and pulling
and are also good for the junior age groups when used with the BOLA
on its shorter legs.
The accuracy of your BOLA is affected by the condition and
consistency of the balls that you use. Do not mix new and old balls
as the best accuracy is obtained by keeping balls in batches so
they are all at the same stage of useable life. Do not use balls
that have lost their dimples.
Your BOLA machine is happy to deliver normal cricket balls
but the wear rate of a leather ball is high and the consistency
of the machine will be compromised.
Unbreakable springback stumps are also available and are suitable
for indoor of outdoor use.
The standard legs for the BOLA give a ball delivery height
of 2.2 metres but sets of shorter legs are available for lower operation
heights, which reduce the bounce of the ball for younger players.
Changing the legs takes less than one minute.
Accepts any BOLA machine with no modification required. It
enables the machine to be easily wheeled around without dismantling
and so maximises the time in use. It also provided improved operator
