Ok so this is a question that my coworkers disagree on. When tightening the lock nut on the spindle is it ok to tap it tight with a piece of brass? One of my coworkers says "All I know is where I use to work they always said don't do it" My other coworker says "Well the spindles are spring loaded so whats the big deal?" I know the reason why its done, so that there is repeatability when you turn the grinder on after its at a dead stop..... at least thats what I'm told.
So what is the true way? Honestly for what I do its irrelevant, but I've been wondering about this for a while.
