Uniloc joint straightness

[fish2]

What makes the shaft and butt straight when connected, the pins or the flat surfaces of both shaft and butt? if the surfaces is not true, will it still be straight when connected?

Both.
No.

The Uniloc pin install has to be precise or it doesn't matter how good the joint faces are.

To expand on that, all pins need to be precise. For fish2, the more precision you have making your cue in any part of the process the better off you will be at the end.

Thanks for the replies, I am not a cue maker, so I sent it off to have the pin pulled, bored, tapped and re-attach, cue is now perfectly straight
