BSA RGS 6082 alloy steering damper knobs – D’Oh!!!
Here’s what can happen if you don’t tighten the chuck up enough! I had it gripped on the shaft but as lightly as i dared as i didn’t want to mark it, but it wasn’t tight enough so it grabbed and spun it ripping off teeth on the way – double D’Oh! I didn’t make the same mistake on the next 2, I used some plastic under the jaws for protection and did the chuck up nice and tight!
