The Broken Arm Project direct-rotary by Special Technique is constructed from brass and copper stock, and a clamp for holding pins in place in my old roommate’s arm. She fell of her motorcycle and had quite a bit of reconstruction and therapy for her broken arm. During her healing she had pins sticking out of her arm and this crazy stabilizer arrangement holding the pins in place. When she got the pins removed, the hospital sterilized the clamps and gave them to her. I inherited one of them and made this machine from it. The clamp/tube vise is made from some high tech alloy that’s extremely hard to work with – I dulled two hacksaw blades and broke my 8-32 tap on it. The motor and flywheel are from our friend Dan Kubin in Kansas City, and there’s a one pound coin and a few bits from an old clock. This machine has a 3mm stroke and is perfect for color packing. The Broken Arm Project direct-rotary is priced at $400. Make it yours here.
