Make-up Special Effects & Stop Motion share many common fabrication
methods and especially the use of Foam Rubber Latex materials. There are
different methods to fill the mold ..... one is .... by
painting each mold half with foam latex, then spooning in extra foam and
closing the halves to squeeze out the excess. Another method to fill-up the
mold is by injecting the foam using a very large syringe tool aka Foam Latex
Injector Gun. Both methods work and both require practice
and trial and error.

One ... 3 inch
inside diameter x 6 foot drain pipe. 6 foot is the shortest length I have
Two ... 3 inch end caps
Two ... 2 inch flat washers
One...1/2 x 2 inch bolt and nut
One... 3 inch DU-BRO low bounce model airplane tire
One ... 1/2 inch plastic water pipe comes in 6 foot lengths
One ...1/2 inch plastic threaded male coupling
One ... 1/2 inch plastic threaded female coupling
One each ..... of CPVC Cleaner and CPVC Cement
One ... 24 inches X 1/2 inch plastic sprinkler system pipe
One ...1/2 inch threaded plastic sprinkler system coupler
One...1/2 inch threaded plastic sprinkler system Tee
Cut a 24 inch long section of 3 inch drain pipe, use sand paper to sand the
ends down until the end caps fit snug but not so tight that it is difficult
to remove them.
Take one of the end
caps and drill a hole large enough to get a very snug fit ofthe 1/2 inch
water pipe then cut a piece of the water pipe 3/4 inch in length and test fit
the end cap and male coupling. The base of the coupling should touch the end
cap and the water pipe should be flush with the inside of the end cap. If
everything fits the glue them together and set aside.
Cut a piece of water pipe 8 inches long and glue it to the plastic threaded
female coupling when the glue is set, thread this to the end cap with the
male coupling. This is the nozzle; you can make the nozzle any length you
want. I found that 4 inch and up to 8 inches are most useful.
Remove the plastic wheel from the model airplane tire. Take the Nut and the
1/2inch threaded plastic sprinkler system coupler you want the nut to fit
half way down the coupler you might need to use a dremel to remove some of
the plastic to get the nut to fit. Once you get the nut to fit inside the
coupler, glue it in place and thread the other end to the 24 inch X 1/2 inch
plastic sprinkler system pipe and set aside.
Take the remaining end cap and drill a hole large enough for the 1/2 inch
plastic sprinkler system pipe to slide through without binding. Run the pipe
through the end cap and put the Tee on the pipe to form a handle. the glue
should be set on the nut by now so you can take the bolt place 1 of the flat
washers on it then the tire and another washer now thread the bolt-tire
combination to the end of the plastic sprinkler pipe. Congratulations you now
have a plunger for your injection gun.
All the glue should be set so fit the plunger in the drain pipe, you can
adjust the plungers fit by tightening or loosen the bolt. Now fit the nozzle
on theother end and you have a completed injection gun for $25.00 ('04
prices). This is a front loading gun so take off the nozzle to fill it.
You can replace the drain and water pipe with clear plastic plexiglass type
tubing but the cost will go up if you do.
If you use the Johnson and Johnson past wax thinned with alcohol as a
releasefor foam latex you can use the left over Stearic Acid that comes with
the latex kits to prop up you injection gun for a photo like I did.
Good luck! David Schlatter
