Ben Fleskes (benfleskes@msn.com) asked for suggestions for
missile launch mechanisms:
My dad and I used to build some rubber band based
missile/torpedo launchers.
1) Use a 2x8 plate (a) as base.
aaaaaaaa
aaaaaaaa
2) Add one 1x4 technic beam (b) and five 1x2 technic beams
(c) on the plate:
b
baaccccc
baaccccc
b
3) Put an eight long technic axle (-) into a =o technic
piece (fits on the end of a technic axle):
-------=o
3) Pull a rubber band (") through the =o technic piece:
"
"
-------=o
"
"
4) Insert two technic pins (_ and ~) into another 1x4
technic beam (d) and put one end of the rubber band
around each technic pin:
""""
_d "
d o=-------
d "
~d "
"""
5) Insert the 1x4 technic beam in the free slot on the 2x8
plate and insert the technic axle in the far end of the
construction:
b_d""""""
badccccc "
badccccc=o
b~d "
"""""""
6) Put a 2x8 plate (e) on top of the construction:
b_d""""""
eeeeeeee "
eeeeeeee=o
b~d "
"""""""
7) You can now pull the =o piece back and insert a missile
(o=-----) in the other end of the launcher:
b_d""""""""
eeeeeeee """
o=eeeeeeee-----=o
b~d """"
""""""""
8) And let go:
b_d""""""
eeeeeeee "
=----- eeeeeeee=o
b~d "
"""""""
Play well,
Jacob

| Thanks Jacob for the idea. I now have a new working prototype. It uses a Lego bungee cord instead of a rubber band. It also holds five missles stacked in an angled from the firing chamber. It work something like this: 1) Pull the firing pin back 2) (...) (25 years ago, 30-Apr-99, to lugnet.build)

| Has anyone had any success building pnumatic powered missles out of lego. Given that the air tubing doesn't provide enough air flow does the following idea sound feasible. Pump air into a hollow air chamber made entirely out of bricks. A 1x1 (...) (25 years ago, 16-Apr-99, to lugnet.build)
