Suspending the Mini Catcher as a
Pendulum
Secure the rod clamp on top of the support plate to a
support rod that is clamped to the table. Cut two pieces
of string, each about one and a half meters long. Thread
one string through the front two holes in the ball catcher.
Thread the other through the back two holes in the ball
catcher. Thread the ends of the strings through the holes
in the support plate and secure them, making sure the
catcher hangs level. (See Figure 2.)
Velcro Assembly
To enable the user to measure the height to which the
pendulum swings, a thread must be connected between
the ball catcher and the launcher. The amount of exten-
sion of the string shows how far the pendulum swung.
One end of the string slips through a Velcro assembly on
the Mini Launcher base, and the other end threads
through a hole in the ball catcher. (See Figure 3.)
➀ Separate the Velcro hook and loop strips.
➁ Cut two square pieces of Velcro hook and one square
piece of Velcro loop.
➂
Determine the approximate height at which the Velcro
assembly will be applied. This is determined by the
approximate height of which the ball catcher hangs.
➃ Remove the protective covering from the back of each
Velcro square.
➄
Arrange the two square pieces of Velcro hook and one
square piece of Velcro loop onto the vertical plate of
the Mini Launcher base as shown (Figure 3).
➅
Cut one piece of Velcro loop 5 – 6 cm long. Do not
remove the protective backing.
➆
Tie a thread to one of the front holes in the ball
catcher as shown (Figure 3).
➇ The other end of this thread will pass between the
square piece of Velcro loop (attached to the Mini
Launcher base) and the long piece of Velcro loop
which should be applied to the three Velcro squares
attached to the Mini Launcher base.
