Ok. I have the first part of the shoulder joint complete.
I decided to write some instruction here to help you guys later on when the model is complete. This isn't an over complicated part but may be tricky to assemble to some. You just need to do it in the right order to make it painless. That's what this post is for.
Cut out these two parts first. Roll up the pin and use plenty of glue as this will help keep the pin solid once it's dry.
Now, cut out the holes on the main joint part pictured above. Be sure to take your time cuttng, it's a good idea to cut just inside of the hole. Leaving a thing white sline going around the edge of the hole. This will help with a tight fit. Also, if you've cut too small a hole, you can make it bigger by inserting a pen or pencil and turning it in the hole to widen it a bit.
Then insert the pin and open out the tabs and glue into place. Again using alot of glue as it will help keep this part solid later on if you're planning on posing this model later. If these joints will work of course! LOL
You'll have this:
Then continue to score and preshape the part:
You need to glue in the inner part of this joint first. Start at the bottom and work your way around untill all the edges are fixed in place:
