Hey there, I'm going through Jit's build and I've just completed adding the first synchromesh cable and tightening it on the Y-axis. I'm having a little bit of trouble though getting the tensioner adjustment screw to tighten into the plastic parts (one being that small semi-circular bit) that the cable wraps around. The tensioner screw comes in and out off the hole with no force applied, I tried giving it some pressure when attempting to screw it in to make the final tightening adjustment to the cable but it's not tightening at all. In some pictures I've noticed there is a nut on attached to the other side of the tensioner adjustment screw, some pictures it's not there, is a nut required on the other end for it to tighten? What model of screw goes into those plastic parts so I can be sure, I've a kit that didn't come with a bill of materials.
