Yes, I hate the sounds of metal grinding too....

Brett, yes mate, I think in hindsight the bush might have been
a bad mistake. It's easy to bore the block out to suit a ball race
but I really thought a bush would be ok at the non thrust race end.
You can see from post #70 how the cradle arrangement is.

When first set up the entire carriage had zero end play(thrust) and
zero side play (bearing one end and bush other)
Now after probably a ballpark figure of only 10 complete revolutions
of the worm gear there is zero end play (thrust) but some obvious
play in the brass bush.
This will have to be re-made, no two ways about it, so I may as well
install a ball race.
