I understand you have a Phd in metallurgy? Maybe you could answer, or
comment on a "dumb ( ? )" question I've often thought about, but never
tried or researched?
Say, in HO scale, 87.1:1, we physically scale-down the prototype
dimensions by that ratio. What if the car were built of the exact same
materials as the prototype, would the weight scale-down by 87.1 also?
A 60,000 lb. car would then weigh 689 lbs. in HO?
