GOT A HANDLE
I like to use my Serdi pilots as go-no-go gauges when I hone valve guides. I made this aluminum handle from a piece of 1-1/2” diameter rod. I turned the outside for a comfortable grip and bored the center to hold my pilots. I select the appropriate one for my guide clearances and hold it in the handle to make it easy for checking when I get close to size. Also, a tight pilot gives me excellent concentricity.
