Been a bit delayed in getting this done (visitors, lack of time, other things that needed doing) but finally found my “Dremel-a-like” drill and made a further modification which I’d had in my head.
So drilled out the base of the skull and backwards from the eye sockets to create a route for the LED lights to illuminate the eye sockets. Then added a small, round ball of set acrylic putty into each socket. Will add a decal to the eye ball from the SFM:uk Eye Decals sheet (sorry now sold out).
Also got the few decals that are needed printed out on some inkjet sheets. Managed to find a few Russian words on Google (hope they are right anyway) and printed them out. There is a pilot label, which says Cosmonaut Smirnov, the label by the gauge at the back reads Oxygen and there is another which says Caution. Plus the Russian star and CCCP markings on the chest and there is a hammer and sickle for the base.
Used Smirnov because it is apparently the most common Russian surname.
Visor has now had 3 coats of Tamiya clear orange and starting to look nice and shiney.
And finally with the lights on.
So just need to put some matt coat on the painted parts, so sort of airhose around the front and then start to add so weathering.
Thanks to the folks over on SFM:uk who voted that this should be on Mars.
