These are our small pillars. The large ones were
such a hit back in '02, we decided to add two more small ones in '03.
The frame is simply 2"x2" boards cut so the box is 4' tall,
2' wide x 2' wide. The 2"x2" boards are glued with Liquid Nails
adhesive then nailed with a pneumatic nailer to form a box.
The box is then covered with brick paneling
available at Menard's or other home centers. The paneling is interior
so I placed the 4'x8' sheets on the driveway on a HOT summer day and sprayed
them with Thompson's Water Seal. I sprayed them again and again till
they would not accept any more sealer. I used about 1 1/2 gallons per
4'x8' sheet. The sheets were cut to fit the outside of the box and
three sides were nailed on. I also added a 2"x4" across the bottom to
support the pneumatics. I then painted the entire inside of the box
black.
Here you see the center 24" pneumatic cylinder
mounted to the 2"x4" on the bottom of the box. Then I used a 2"x2"
towards the top to support the top and keep it level. Next to the
cylinder is a 1/2" x 24" black pipe mounted to a pipe flange. This is
used to keep the monster from rotating as he/she exits the box.
I next made a support for the monster. It is a 3/4"
aluminum channel. In the center I have a hole to mount to the
pneumatic cylinder. The first picture shows the 1/2" threaded rod that
slides in the 1/2" black pipe to keep the monster from rotating.
Next we needed a way to mount the monster.
I used 1/4" threaded rod and ran them a few inches from center of the
channel. These were left long for now.
Here is the support mounted in the structure.
The head for the monster is a mask filled with foam.
The mask is impaled onto the two 1/4" rods then the foam lid to the box is
added. Finally the lid is secured with locking 1/4" nuts. Add
some burlap for the body and you are done.
Of course I added a pneumatic solenoid, air line, a
trigger mechanism, a light that turns on when the unit is triggered, a timer
and more. There are two. One on each side of the yard. I
added in '04 gargoyles to the top of each of these as well. The
gargoyles have blinking red eyes to draw your attention to them.
