Welcome to another one of my custom action figure tutorials. I'm sure you've come across figures where the arm is a straight hinge and can't be turned because its missing the bicep swivel. Well there's an easy way to fix that missing range of motion and that's to turn the straight hinge into a swivel-hinge. You'll need a Dremel tool with a drill bit and engraver/dentist burr but, x-acto knife, and a fodder figure with a ball-in-cup hinge swivel you can cannibalize for the new figure.
