Ok. So I bought my second Halo on Labor day as i was taking advantage of the special FK was having. Received my machine (4.0) and used it for the first time last week. The vise is not tightening! I am using the red tatsoul wrath tubes. I can tighten as much as possible and the tube can still be twisted. I've tried switching the vise around and still no go, it keeps twisting. Any advice or anyone else have this problem? I'm hoping i can just have a new vice/screw setup sent. Thanks in advance!
