Took me about three solid hours to very carefully dremel out the two halves of the Dragon torso to remove as much extraneous mass as possible whilst keeping enough rigidity to survive the moulding process in the same shape it started it in (I hope). Removed at least enough material that in metal would make about 3 Manbane the minotaurs, I think. Also covered myself from head to toe in flakes of dremelled-out putty, looked like I was made of vivid coloured static grass. Oddest bit was uncovering all those layers of work from the inside-out, like looking at a wasp nest made of loads of layers of differently coloured materials. Bits of wire, brass rod, a ribcage, mad ideas like dividing the body in two along the horizontal that I had forgotten about, all were revealed like some miniatures-based epsidoe of Time Team but one where they actually find a lot of interesting stuff and not just a shard of pottery.
Spent the next 4 hours just going over the scales and removing any little bits of putty or plasticene from between scales or flakes of weird crap or bad sculpting. Fixed up the original masters for the head and stuff in case they are needed.
