[ATM] Density of materials chart



Hello all

I got tired of looking this stuff up all of the time so I made up a 
little chart from various sources. They should be looked at as averages, 
especially for the wood and ply  figures.  The metals should be fairly 
accurate but can vary slightly with different alloys.  The wood figures 
can vary wildly with various grades and dryness, but should be a good 
starting point.   If anyones has some others to contribute I will add 
them to the list and eventually post it on my web page under a list of 
resouces.
