All measure are in European SI
1 inch = 2.54 cm = 25.4 mm
1cm = 10 mm
You will need the following Items:
-2 piece jar lid [10 cm dameterl
-1 piece of a doctofs rubber glove ora balloon
-some strorger wire or paperclipsl for the shaft]
-2 pice of thin wooden rod [d=3-4 mm]
-2 piece straw [the thick one]
-2 beer can [you have to drink the beer first!)
-1 piece plastic ball pen's outer shell
-10 pieces of pearl
-A little piece of depron or EPS foam
differently thick cartboard
-1 small tin can [the bottom, the lid and the body)
silicon, quick dry glue, epoxi
We drill a d=12mm hole in one of the lids, the
border of the hole is approximately 12 mm far
from the side ofthe lid. This will be the top.
Now we fold out the knobs of the lid.
We cut outa d=93 mm disc pattern from a thicker
mrtboard. We also cut out a 24x297 mm and a
24x20 mm strip from the cartboard. We draw a line
in the middle of the lorger strip[12 mml,now we
bend the strip around the disc we earlier made and
Que the two ends together with the smaller strip.
If it's dry we put the pattern disc in the reel, we set
it on the line and then put the reel in the lid and
Que it to it.
If it’s dry we fill up the gap between the lid and the
reel we silicon paste. If the silicon is dry we push down
the pattern to the bottom and we mark its center on
the lid. We stab the center of the lid, the hole has to
be big enough for the shaft to move back and forth,
but not to big!
The displacer is a d=87 mm and 12 mm high cylinder.
Depron or EPS foam. We drill its center, fill it up with
epoxi and put the shaft in it, when it’ s almost dry ajust
the shaft to 90 degrees in every angle.
We cut out a 15 mm long piece from the pen's shell.
From the tin can's lid we cut out a disc the same
diameter as the pen's, we poke out its center for the
shaft. We glue it to the pen. This will be our bearing.
We put the displacer int he cylinder, we pull the
bearing ont he shaft and glue itt o the lid. When it’s
almost dry we check that the displacer can move
smooth, it does not hit the side of the cylinder if
Now we put the displacer permanetly in place, we put
the whole thing ont he second lid's outer surface.
We glue it with quick dry glue to keep in place and
then paste it around with epoxi. This will seal our
When the glue is dry web end the shaft of the
displacer to the shape show non the picture.
