rust & weight

[FC P/VAN]

I am in the middle of removing the l/h sills on 1 of my wagons, it was 2/3 full of rust pieces. the outer sill had only very few minor thin spots and the inner is still quite strong (going to replace anyway while i am in there), just wanting to find out where all this bloody rust comes from??  appears to be far far far too much to be from the sill outer only.

once i emptied all the rust from the sill i was wondering how much it weighed so i got to the scales and was surprised to find 4.2kg of rust had come from inside 1 sill. are our cars getting heavier with the more rust they get and steel they lose, has anyone weighed their project before and after "restoration"??

Rust tends to be heavy due to its moisture content

Hi FC P/Van,

Your 4.2kg of rust comes from 'about' 3.4kg metal (hard to say exactly since rust is a mixture of oxides and hydroxides). But  looking on the bright side...this means your wagon is 99.7% rust-free! Man I should be in marketing...

Rust is also bigger than the amount of original steel it came from, pretty sure it is about 8 times the volume.

Remember reading in some engineering magazine that rust has a very strong expanding force and has been known to break bolts on structures when the rust was trapped in between two beam plates.

i honestly never thought rust could be so interesting to learn about, but i also wish i never had any to study.........lol

it is great to hear everyones different views on these topics that i have never heard anyone ask about before.
