Prop Balancer

This is a single piece prop balancer, that can fit up to 10" props spinning all the way around. I wanted a one piece design for alignment and accuracy at the expense of portability/storage space.

For use with: http://www.amazon.com/gp/product/B001BHK54W/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

(or any other figertip balancer with the same axle length, approximately 1.92in/48.8mm)

Also need 1/4 in magnets, I had these sitting around:
