I started thinking about being able to adjust him. I have used bolts with wing nuts under the shoulder so if I want to change the shoulder arm position I can easily do it. Same with the neck. I have also used a junction at the pelvis so I can swivel it left or right or up and down. Problem is that the pelvis is not real real secure as it would be with a solid pipe with no break. But because It will not be moved around alot should be o.k.
Got the Spine problem figured out. I did find a weak spot however. The shoulder part that holds up the Arm is a weak spot and has a hard time with the weight of the Arm. Will have to beef that up. Thinking of embedding a hefty bolt for strength. Will see tonight.
