RT Mod Helmet
Unlike the FX helmet kit, this lid required
a fair amount of cleaning up before test fitting and assembly.
After washing and sanding with a 3M wire wool
pad, the outside was masked off (as well as the area in the dome
where the parts will bond) to prevent overpsray. The internals were
given a couple of coats of Vallejo Matte black plastic primer (this
stuff bonds to the ABS really well).
The eyes were removed with a dremel routing
bit, and sanding drum. Final shaping was done with jewellers files
and 600 grit wet/dry paper.
The four "teeth" of the frown were
first drilled and then cut out with a jewellers file, and finished
with narrow strips of 600 grit sandpaper. The masking is just for
a rough guideline for shaping the "teeth".

Next up the frown was masked off using tamiya
masking tape (nothing else compares to this stuff for "bleed
free" sharpness) and cut up plastic carrier bag :) .
The back side was also masked to close off
the holes to prevent the black interior catching any spray through.
A couple of coats of Humbrol grey (156) was airbrushed on, after
a couple of minutes with a hairdryer the masking was removed and
allowed to dry for 24 hours.

Masking the mouth was a bit of a pain, about
45 mins of taping and cutting. Airbrushed using Tamiya XF1 flat
black enamel paint.
Also the decals that came with the lid are
damaged, so I am trying to get hold of some more from the supplier
of the kit (no quibbles, top bloke replaced them :) )
I decided to dress up the cooling fans in this
bucket. Using 2 discs of styrene, painted yellow, decals applied
(laser sensor custom mecha decals from Tim at CoM), and then several
coats of clear varnish (Johnson KLEAR). These where superglued to
the fan centre.
The black painted sculptors mesh was fitted
over the top to give the finished fans. I will probably paint the
cables black to disguise them.
I got hold of some excellent green lens material
(Cheers Kenny )to replace the single piece of grey acrylic supplied
with the kit. After trimming in was molded to the shape of the eyesockets
by softening with a heat gun. They were fixed in place with hot
glue,then I cut some self
adhesive foam tape if half lengthwise and applied to the lenses.
The mesh supplied with the kit was formed around
the inside of the frown, and secured with hot glue, I am probably
going to cover the inside of the lid with foam drawer liner, painted
metalic charcoal, which will cover the gluey mess.
The two fans are mounted on floating brackets
made from folded brass sheet, bolted through the rear of the mic
tip depresions, the tips will be attached to the other end of the
bolt shafts. Two 9v battery boxes to run the fans fix to the inside
of the tubes (probably via a brass bracket and velcro-so they can
be removed easily to change batteries).
OK, rework time...........althought the fans
work alright, the mesh decreases the air flow. After experimenting
a bit more, the air flow can be increased dramaticallly by removing
the mesh and positioning the fans further away from the helmet wall.
Using brass rod, a "floating" frame
can be fixed to the same bolt points as before (through the rear
of the Mic tip depressions).
The battery boxes are riveted to a brass strip,
which can then be attached to the inside of the tube (front section,
so weight is forward)
The brass strip is flexible enough that the
battery containing section of the box can be slid off to change
batteries.
The ear pieces required a fair amount of shaping,
and after applying the decals the finished item looks like this............................
