This is probably the most complicated project I've done, I started it over a year ago, inspiered by 19th century finger exercisers, then it was put on the shelf until I finally decided to give It a go again.
It's made mostly of leather and brass. It has endless hours of grinding, filing, and sanding put into it, the hardest thing was to actually make it fit my hand, and be functional,this was achieved mostly by trial and error (and a lot pain for my fingers!) It still need some minor adjustments. But I really like how it turned out, and I hope you do too.
And I also got a flickr site now at: http://www.flickr.com/photos/curiomira You are welcome to visit.
