    Machine is going really well, I've made a few parts for the local flying club.

    I'm now in need of a rotary axis, I have a couple of options:
    1. Use the headstock and tail from an old rusty taig lathe I have with a belt drive off of a stepper or servo,
    2. Convert a rotary table,
    3. Buy one.

    I need it quite quickly, can anyone recommend anything that is known to work, even if it is one of those chinese harmonic drives? I need something with a 100mm chuck and minimal backlash as it will be used for continuous processing not stop/lock.

    I was looking at this, seems extremely cheap for a harmonic drive but they have them in europe so I could get it fast:
