Nuts,Neck and Time -Lack off!!!

Well not much is happening on the Guitar Front at the moment due to work and dometic chores (renovations).

I have decided to re cut the nut as the other one's that I made ended up with tiny black specs in them from the Wet and Dry - I think.

I am not too worried about the guitar sitting at the moment as it seems that the finish is improving as it drys out- or it might be me!

My next drama is this business with the neck moving.

The more I think about it the more I reckon that I have stuffed this up big time,but there is no turning back.

I have had a good look at it and the only other thing that could be ,is the tenon on the neck is a bit loose.That I can fix!

Also I think that because of the shelac thats under the cheeks,it gives the neck something to slide on?? That too I can fix!

Any ideas regarding the black specs /marks in the nut are welcome!
