After doing that, I adjusted the worm end float and found that, visually, the backlash is massively better after tightening this up. May need to adjust it a little still once I get it under the stars, but I can tell by watching the end of the worm when I slew in dec that the backlash is way better.
I'd certainly agree the tension on the end of the worm/bearing is every bit as critical as the grub screw tension on the worm/gear. Has to be firm, but not so tight that you get binding as the assembly is rotated all the way around (there is usually a tight spot somewhere if you get it too tight).

What about padding the worm/bearing ends though - is that possible or required to optimise the worm/gear mesh? Be interested to hear from gurus?
