I got my 250 brass inserts today. I cut off bad 1 inch doewls approx 5 inches long. I put in 33 inserts for practice. I think im ready for the real thing now. I have one question. if i have an insert that is 1.030 how deep do most cue makers drill and tap. I have two thoughts. What about an "air pocket" which i think is not desired? What about Glue relief space. Just wondering what a typical drill and tap deth are? And is 5 minute appoxy ok to use.
