In the 5th installment of my claw machine tutorials,
Skill Crane 105: Reclaw the Claw, I demonstrated the process of replacing the claw fingers on my crane with new ones for a jewelry claw. One of our members, 3756will, replaced his own claw recently and it turned out great.
Check out his video showing the aftermath
