In response to a post when the poster was overly complicating an answer to a simple question in an attempt to show vast superior knowledge, a wise man here once said, "He asked what time it was, not how to build a watch".

That's a good one.

So - as long as we're this far off the subject - anyone else been doing this long enough to remember when you only bought the lining and had to rivet them on yourself... I remember, as a kid, being curious about how flexible the lining was - then "SNAP" - my dad wasn't too impressed with my curiosity as we went after another set.

Yessir, that's what I was saying, shops I worked in would just buy the lining and our foot operated brake machine did the rest, punching out and pressing in new rivets, mostly air brakes. We also had a drum lathe so we could turn scored drums and/or arc the drums/shoes to fit the new lining/drum. Didn't mind doing air brake systems but hated (and still hate) doing hydraulic brakes.

Do you mean the guy who tries to brag about his work experience in his signature? But keeps posting incorrect information?

You're the one who tried to explain how the watch works, and got it wrong. Look in the mirror, Mr. Pot.
