Well, I finally have something that might be worthwhile contributing. Since 1986, I've been pining after a set of Colonial Marine armor. Close to oh, I'd guess maybe 12 or 13 years ago, I tried out a Golden Armor set. Got rid of that pretty much right off the bat, and a year or two later managed to get ahold of a Riddell set of fiberglass Dietrich stunt armor. Much, much better. Wore it a few times to costume parties and whatnot. For the time being, I'm happy. Then I start getting the itch to have a Colonial Marine airsoft loadout. Hmmm... Riddell set too fragile. Upgraded to SPAT helmet. Happy with the steel and strength of materials, but not so much with some of the innaccuracies. Upgraded to SPAT's newer lobster plates. Much better, but still... Need new front plate, new mic... Hmmm... What to do?
Armor still too fragile. Consider creating an outer layer of thermo-formed polymer. Probable loss of detail. Idea scratched. Consider hand-hammering one out of aluminum. Insufficient technical expertise, lack of equipment. Idea scratched. Hear rumors of airsoft capable armor coming from MAA. Product in limbo indefinitely. Idea scratched. Reconsider SPAT armor. Possibly not strong enough for heavy-duty use. Idea scratched. Consider metal coating Riddell armor. Informed coated items will only be as strong as the substrate. Idea scratched. Frustrations deepen. And then...
Why not simply cast my fiberglass suit in aluminum? After much searching, I finally located a metal guy locally willing to take on small scale projects. My first step was getting ahold of a front plate and lobster plate set from a member on the RPF. Turning these over to my metal guy, I got a lovely set of cast aluminum plates in return. They are very lightweight, and quite strong. Here is what they look like after cleanup, with the front plate mounted to my steel pot:


I have decided to chronicle my project here, so that I can share the fulfilment of an obsession of mine that has been afflicting me since '86 when I saw Aliens in the the theatre with others who might be similarly afflicted.
My metal guy now has one of the greaves to work on now. I'll be pieceing this together bit by bit as I can afford to. I also have a pulse rifle build going on concurrent to this project, wherein I am completely overhauling my G&P kit (perhaps getting rid of it might be more accurate) with HCG shrouds, a SPAS cage Maruzen combo, and other Phil S. parts. Also already enroute is a working mic and earpiece setup courtesy of a member in a Land Down Under. I expect the helmet ought to be done soon! I hope this thread will be of some interest to you all.
