Drop D tuner not staying in tune...

[Jamesemt]

I fitted a drop D a couple of weeks ago.
Whenever I drop the tuning peg and then click it back up it goes slightly out of tune. The second time I do it the tuning goes way out...

Is this normal?

Lubricate your nut.

With a very soft pencil e.g. 4B.

It may depend on the make of tuner you have.
I have a Hipshot "D" tuner and you have to keep tuning via setting the gearing gap by dropping and tuning from E to D a few times.
