Miller, Haven't we seen photographic evidence of that rarity here?

I look at it like this.
Cars used to weigh 6000lbs.
You can reduce material, change materials, until something breaks. Then add back material for a comfort zone.
That's pre-manufacture, and it has worked great for a couple centuries or more.

Can't do that with finished products as easily.

So, scrape away at your barrels at your own risk.

Can you lighten a 55 Corvette? Sure! Would the next guy want you to? Hmm.

Out there doing it best I can.
