I've been quizzing Tormach on the lathe and still can't get a solid answer on a 5C collet closer. I would be looking for something that was pneumatically actuated so I could do automated bar pulling/feeding. Is there any info out yet on compatibility? They have mentioned a closer, and even shown this in videos, but I'm worried about availability. If there is an aftermarket option available, it may be worth buying it for the lathe out of the gate.
