The Challenger is a retired Army EOD Tech and was injured by an IED in 2012, sustaining a left above the elbow amputation, a right below the elbow amputation and a left hip disarticulation amputation. His right prosthetic is a myoelectric and his left is body powered. He had osseointegration surgery on his left arm 3-4 years ago. His main hobby is woodworking and has a beautiful shop. He currently has to use multiple off the shelf end adaptors (terminal devices) on his left prosthetic arm. Each tool requires its own end adaptor, and he still has to use both arms.
A device to stabilize and add a material clamping function to a Festool Domino Joiner. The "tricky" part to this is it must be able to adjust to and function at a range of 0 to 90 degrees.
