Seeking Action Figure Joints?

Posted in Custom Workstation

Hey there! Hoping for a little help!

I live in an area that has limited local options for buying figures (used and otherwise), so finding the parts I need to customize figures and add articulation has been a bit of a hassle. I've been looking into buying sheets of joints online recently, but everything seems to be ball joints--which are great, but not what I'm after. I'm hoping to find some swivel/hinge ones, or learn how to make an 'at home' substitute, like the swivel-joint-screw trick. Does anyone know a hobby store I can look into, or an easy fix?

Thank you!
