The Iron Man. Part2 - Beginning construction

 Ok I said I would be going over RTV moulding and Resin casting..Well I decided just skim the subject coz it's..
A) More a technical discipline rather than an artistic endeavour.
B) There are resources on the internet where you can glean more/better info on this subject (just Google casting in resin).
The Masters(in grey)
and Casts(in white)

Assembled master and cast.
 Having decided I wanted to make my figure("Irons" from here on in) a pose-able figure, I would need multiple joints for hips,shoulders,knees and elbows(8 in total) the quickest and easiest way to do this was to make a "Master" and cast copies.Once a prototype hinge joint was made,it was split into its component parts and cast in RTV rubber,a pourable slow curing mould compound. Once the RTV had cured,Masters were cut from the mould. Polyurethane resin was used to make the joints I will use on "Irons" for speed and because the casts are single pour moulds they are also structurally stronger.
 I'm going to use a Bessemer furnace as a torso(see previous post),I decided to make a scale model of said furnace,and being a bit strapped for cash right now I rooted around the house for scrap(plastic) and any forms/shape that I thought would fit in with my design("Iron's" belly is a hangable Tent light,and his head is a base from a pencil sharpener). Necessity IS the mother of invention after all. 
The inspiration.
Rough Marquette Sans legs/arms. 

Torso and head construction.
The torso needs more work and lots of detail to be added before I feel satisfied,but watch this space as next time I will be making legs and arms for our hero..
