I think your math may be a bit off. Since a half inch hole removes pi * .25"^2 * .125" or .0245 cu in, and aluminum has a density of .0975 lbs/cu in, each hole removes .002393 pounds of material. 100 is only .2393lbs. 100 1" holes does lose 1lb though. A note to those needing to lose weight, 100 1" holes take a while to make; slicing and dicing any steel you may have will be much more time-effective.
