Both of those methods would seem to make getting the bottom side of the chain sculpted quite difficult. I remember a tutorial I saw quite some time ago, although I can\'t find it now, but I can list the general idea easily enough, since at the time I thought it was quite similar to the method of carving wooden chains. Anyway, this may make more sense if you use the pictures with the other tutorials to visualize what I\'m trying to say, here it is:
1> Roll out a thin sausage of putty, make it into a long thin square rod shape.
2> Let it cure up and harden a bit.
3> Look at the end, divide it into 9 squares, cut the 4 corner squares away down the length of the putty. So you are left with a long \"t\" or \"x\" or \"+\" type of shape.
Note: It may be easier to just sculpt the \"t\" shape initially after mixing the putty, in essence doing steps 1-3 in one go. Although probably difficult for anyone without alot of sculpting experience, like me. You could perhaps make a long strip about the width and thickness of the chain links, then lay a long thin sausage on top of it, smooth it out and then repeat on the bottom? The bonus for this effort is the links will be rounded on the outer edges and less work to fiddle with later on I guess. Anyway, moving on.
4> Let it cure a bit more. If need be.
5> Cut out little triangles all down one side, then offset on the next ridge, then repeat for the other two ridges. Make sure to match up the triangles you cut away on the opposite sides. Or you could just pinch the sides like in the other tutorials above type of thing.
6> Lastly add the finishing touches, clean up the edges, sculpt some indents where the hole in the chains would be, etc.
This will leave you with a solid core down the center but it will look fairly decent when painted up, viewable from all sides/angles. Much like the chain the goblin is swinging around.
