Impact 3 Section Double Articulated Arm with Camera Bracket

I’m thinking about building a small at-home camera-based scanning system (you know, like books, playing cards, and film) and was thinking of one of these 3-section double articulated arms instead of the usual vertical stand that is seen on most copy stands. This one from Impact can hold nearly 10 pounds so should be pretty sturdy. If you’ve built a copy stand before, let me know if this is a bad idea!
