Bench note · why the groove, not the clip
The clip is named by the bore it fits (Ø85), but you cut the groove: Ø88.5, 3.15 wide, 1.75 deep. Square corners at the bottom so the clip sits flat against the side.
Bench note · why inside pliers
A bore clip (DIN 472) is squeezed to go in: inside pliers. Squeeze it only as far as it takes; bent past that it springs out under load.
