Brass threaded inserts are used for easy removal of the artistic top piece. Many artists make the tops and let people chose which base they like: stainless Whiskey, brass Whiskey, Niles bottle opener, Niles Tab lifter, etc.

The inside thread is 3/8″ x 16 tpi that will match all of my products.   There is a solid band on one end and the other is notched.    Drill a 7/16″ hole 3/4″ deep and push the inserts with the slits going up into the wood. You can either drive it in with a rubber mallet or thread it on the mandrel and push it in that way.  Be careful not to rock the mandrel as that may make the top edge of the hole wider.  *note: if you have tear out of the threads in certain wood species, these inserts solve that problem.  You still may have to use glue with some soft or punky woods.  They work great whether you put the slotted end in first or the banded end, it’s a personal preference.
