This is a 6 month old G11T. I received an email from Tanya and in fact the worm adjustment is opposite from what is shown in a video they put out. Who knew? Any way lubing the bolts before tightening is a good idea. I'm also going to put a shim under the worm block before I tighten it. Seems like the system in the video is much better than what I have. Don't know why they would change it.
