Generally the bore of the drones on the Pakistani manufactured pipes are almost impossible to polish. When attempted, they tend to get fuzzy because of the sheesham (variant of rosewood) is not good. The best you can do is re-bore with an absurdly sharp gun drill and hope that the result is not too open to give a good voice.

I've redone chanters for these and found it a frustrating proposition.
