The Morizumi SCT (Spoke Cutting and Threading) machine is a marvel of simplicity and compactness. Originally designed at Asahi Spoke Company (partner of Wheelsmith for the first 20 years), now it's manufactured by a nearby machine shop founded by former Asahi engineers.
Not that portability is vital, this tool can be stowed in the space of an 8" cube. As a consequence, I've taken it to numerous events and clinics.
Spoke cutting and threading are separated into two distinct operations. For cutting, the spoke hangs over a precision rule while the other end is trimmed by the same shear we used in our factory.
The machine is changed from 15 gauge to 14 gauge by simply loosening the ball ended lever and moving the switch on the left up or down.
Pulling out the knurled pin, disassembles the threading lever linkage.
With pin removed, the moveable die holder can be lifted out of the machine.
