Drilling the Detent Divot
A divot is started with a small drill. The drill size is increased to about 3/32 of an inch - until the detent ball seats properly in the blade divot

Final Detent Fit
After assembling the blade and frame, the detent engagement is checked. The lock should almost touch the blade in the closed position. This ensures that the blade will be held in whenever the knife is closed.

Clip Placement
Placing the clip in position, you can see that the head of the pivot pin interferes
