heheh....I just visited my friends in the machine shop....Showed them a loose ball on one of my throttle linkage pieces....I said "yeah I'm just gonna peen the back alittle with my hammer"
They said "hammer?....no no no...come on over here....we just got a orbital riveter"....So 15 minutes later they orbital riveted the little linkage piece....
PS is peen spelled "peen"??
