I'm looking to make a near life size robot model, but need a sturdy frame to build it on. The head joint must be able to hold about 25-50 lbs and yet be at least moderately pose-able. The rest of the model will be pretty light - fiberglass or the like. Don't need it to do gymnastics, just a standing model I can bend the arms/legs on - as well as mount cast pieces too. It also needs to be free standing or nearly so (rod to hips should be ok).
Does anybody make something like that? Or do I need to have a shop weld me up something...
