I like to play with metal in the garage and my latest project involves using a lathe, mill, and my TIG. My old man lost his arm as a teenager but it hasn't stopped him from taking up various hobbies. His latest, and probably the one he is most crazy about, is golf.

He already golfs in the Mid-80s, but has always wanted to try a prosthetic attachment for golfing. There are a few companies that make them but the most popular one is $800!! I decided I would use it as a learning opportunity and a chance to play around with my tools.

I took some 1" CRS rod and turned a few spring caps and welded those together. These caps were tapped with 1/2x20TPI to match the threading on his prosthetic. I then took some 1" ID pipe and placed some tapered slugs in each end which fit the taper on the golf club. The pipe was then fitted with a 1/2x20 TPI lug to attach the the spring.

Here is the finished project of the initial build. I'm already starting on number two since receiving some feedback. The black coating is Plasti-cote spray.

and my Rev 2.0, which is going to use an eccentric cam locking mechanism. I'll be welding this up tonight with some mounts for the CAM and a lug attachment for connectivity to the artificial wrist (aka spring).
