I experimented with this a while ago. I managed to fire a 10 stud axle about 5
meters using an elastic band setup with a beam stricking the axle. However,
this didn't give a very gun-like contraption, and I never quite perfected a
trigger mechnanism. I might start working on my gun designs again now.
Although not as complex and original as a gun that fires solid lego pieces, a
simple automation band shooter can be made by driving a 24 tooth gear with a
worm drive attached to a motor. Hook elastic bands over the gear and onto a
protuting axle about 15 cm away from the 24 tooth gear. Turn the motor and the
bands will ping off one by one.
