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.

[WRONG]Your math is right, but a quarter inch is not a half inch.
[/WRONG]
However, Luke is certainly right in terms of time. On Thursday you're far better off removing non vital assemblies and parts than cutting holes if you're a pound or more over.
