Bit of a flood ! And a couple of questions.

Thanks everyone.

Jazzcnc, first I must agree that Yorkshire tea is the only proper tea, and I am a southerner too.

Good to know that I measured the ends of the ballscrews right at least.

With the ballnuts, I don`t think I have actually been having any problems with backlash and I am pretty sure the clicky noise is coming from the BK blocks particularly on the Y axis. I am only butchering wood with it at the moment.
So perhaps I will leave them alone, I was just thinking of doing it because I will be doing the ends anyway. I have a vison of loosing many tiny ballbearings over the floor if I try to dismantle them.

I will send you a PM.

Thanks

Ollie

In that case, then leave them alone and just grease the nut.

However, if you do decide to remove the ball-nut don't just unwind it from the screw otherwise you will dump the balls all over the floor. The correct way is to make a tube or mandrel the same size as the screw base thread and wind the nut onto this. Then you can take this to a large tray and remove the mandrel letting the balls fall into the tray. Then you do the same in reverse, re-build the nut onto the mandrel and re-fit the nut onto the screw by winding it off the mandrel.
