Circular Sock Knitting Machine

I'm in the process of building this - should be done within a week if my needles will come in. Really looking forward to it since I started hand knitting a pair of socks ~4 years ago and they're maybe 20% done :D

Prints are pretty easy but two are longish (15hrs and 27hrs on my machine/ settings).

Anyone tried something similar?
