Alun,
The belt is fairly taught to turn the collimator with a Velcro layer wrap around for grip.
The white screws are slackened off 1/2 turn or so from tight to prevent side movement.
The belt is not joined.
I have adjusted both again and will see how it works tonight, and will report back.
Regards,
