As a project for a class at MIT in Cultural Prosthetics, I designed and built an attachment for a young man in New Hampshire who enjoys fly fishing. I met him through Northeast Passage, a non profit focused on disability-related health promotion and adapted sports programs. I also contact Project Healing Waters for advice, and consulted their videos to see what solutions they have come up with.

Their existing designs are functional, but jury-rigged and sometimes literally taped together. I think that a better design that integrates the fishing rod directly with the prosthetic is possible.

It's not a totally finished piece, but I hope the photos and video can help inspire someone else.

The joint is an incremental angle hinge from McMaster-Carr. It's strong (holds 828 in-lbs of torque), light, and easy to set (220˚ range of motion, controlled by a central spring lock). That's actually attached to the rod with a piece of aluminum cut to hold the reel, and then secured by hose clamps. Not the most elegant solution, but I didn't want to permanently attach the (borrowed) rod to the joint.

Josh -

Thanks a lot for posting. Looks like the wrist attachment is 1/2-20" with an FM quick release wrist. I'd be interested to see details of the joint and how it's attached to the rod.
