trigger pocket buffing

[funnsun34]

So have a built a few 80% anodized lowers with my ghost gunner.
The ghost gunner does a great job, however it could use a little clean up in the pocket. I was wondering if anyone on the gunsmithing thread would have a recommendation on buffing the pocket, probably with a drill press. The next lowers I'm going to built will be non-anodized I basically want the pocket be as smooth as the outside of the lower before airbrushing with Duracoat.

thx

Buffing should be ok as long as you didn't get out of spec. What cutting fluid did you use when cutting the lower?
