There is some minor conversion on the model. Since it is an original the platform is made of resin, and known to sag if it gets too hot. I bought some plastic girder at a hobby shop to brace it and rather like the look. Attached to the outside ring it beefs it up, and the bracing both supports the platforn while adding to the industrial feel of the machine. I also added a Khador wreck marker to the base to help fill in all that empty space.
I painted it in four parts. The main machine, the centre ball, the Storm Smiths, and the base. Once painted they were all put together. The ball, platform, and centre torso are all pined together, and the legs are pinned to the base. The colour scheme is my standard Cygnar one, with a few more layers to handle the broad surfaces. The ball took an especially long time to get a half decent smooth look.
