Visco Fuse Machine

An automated Visco (Safety) Fuse Spinning Machine. I built this myself in the spring of 2011 at Franklin W. Olin College of Engineering as a Passionate Pursuit. I designed and built a visco fuse (safety fuse for fireworks) spinning machine. It takes 20 spools of thread and wraps them around a black powder core, and then coats the 1/8" fuse in a waterproof nitrocellulose lacquer. It operates at a speed comparable to commercial machines and is built for safety; it is entirely non-sparking and removed from ignition sources. I designed it completely from scratch and machined all of the parts in the Olin machine shop.
Plans for this machine can be found at www.pyrotechnicmachines.com
