The feet, legs, hips and waist skeletal structure were all cut and built from plywood to give the lower half solidity. The feet where built into the base to give it extra solidity, and the lower section was then slotted into that and fixed with 'No More Nails'. The torso-skeleton was constructed from a series of 1.5cm plastic pipes. Over that was fixed 5mm foam-card to build up the actual body of the titan, finally adding a card skin. Same with the legs. The Head was a complete scratch build by a key-timer at the store called Ben (He deserves all the credit for this baby - he spent blood, guts and many, many hours on this - kudos to Ben!!!) Same again for the weapon systems - 2cm pipes built into foam-card boxes. The multi-scatter on the top-left shoulder hard point was made from bundles of drinking straws with a box built around them - all the shoulder hard points rotate by the way
Finally, wires and gubbins were added around the hips and head.
I would post up the the plans for it put they were literally a half dozen rough sketches of what we wanted with a few measurements on the crucial areas, then we simply went for it on vet nights (and a few others - Ben was there till 4 am on the day of the Apoc release getting it ready)
I'm glad you like it - I'll pass on the kudos to Ben and the other guys. More work is being done on it - icons, stain glass, banners and purity seals etc, etc. If you want to see it, pop down to the Plymouth store anytime if you're nearby.
