My stepdaughter got married in the autumn and had
the reception at our house. The pier had recently given me an old
crane machine, so I got it working and modified the claws so they
would pick up bottles of lager.
To stop the game being frustrating, I had to make it
dispense bottles frequently. This was more difficult than I was
expecting - the solonoids that close the claws are only just strong
enough to grip the weight of a bottle. It did work in the end,
modifying the claws and using foam collars round the
necks of the bottles for the claws to grip.
