I don't have an OPW, just an original brass worm on my G-11. But I have observed the worm's lateral play when moving the counterweight shaft. I am concerned because it may be the main reason for erratic guiding I get (that I am pretty sure is not PE related). The play feels 'big' at the end of the shaft, but looking at the worm shaft, the play translates to perhaps a couple mm across the bearing blocks. Is that normal? I don't understand those who talk about squeezing these blocks together. When I squeeze the blocks together and begin tightening, the block returns to its predetermined positioned when tightened...as you would expect with machined fittings. I don't think I have an issue in meshing the worm and the gear. When I watch a slew (cover off), the worm and gear seem to work smoothly without issue. The lateral play is most obvious and my 'visual analysis' suggests that the lateral play and the mesh are not related. Am I wrong about this? Is the lateral play strictly a function of mesh tightness? From the posts in this subject, it is not clear to me what folks are doing to reduce lateral play. Since the one-piece designs do not appear to be immune to lateral play, I want to try fixing what I have before taking the plunge for an OPW.
