Robin RC-32-1A shoe sewing machine (AKA Chinese shoe patcher) Example pieces 

The Robin RC-32-1A is a hand-crank sewing machine. Designed to allow precision sewing in tight places through tough materials, it is a uniquely useful tool for hobbyists, DIY'ers, and anyone who wants to be able to make quick, lasting repairs to hard-working gear.
It is also a weird machine. It costs just $130 USD at the time of this posting. It arrives through the mail covered in thick, dirty, smelly grease with rough metal-on-metal working friction surfaces and no instruction manual. Forge scale, pitted castings, dirty bearings, and incorrect timing are just the beginning of the journey of discovery that is the Robin RC-32-1A.
