In seeing so many of the great custom combiners on here (Devastator, Predaking, Defensor, etc.), I was wondering if there are any tutorials on how to attach the limbs together. I know people use Bionicle, Lego Knights, etc., but can someone point me in the right direction in detail on how to actually connect the limbs together? Are there any tutorials out there with pics? Anyone's help is greatly appreciated. Thanks.
