I say this, not because it doesn't take weight off, but that the amount that you would have to drill to make a sufficiant dent is impractical. Sometimes your better off playing with different materials (like u said delrin).

I disagree
First, delrin is impractical for many applications. Say you have a 3 foot piece of 2" aluminum square tube that you need to lighten. Delrin or any other plastic would be hard to replace it with. Many times it's easier to drill holes than to design for other materials.
And as for drilling holes, the weight does add up. Especially if you're using 3/16" plate or larger. The weight adds up little by little, but it is worth it. Plasma Cutters can be used for larger holes and eccentrically shaped ones. Cutting unnessesarily long fastners off is also an easy way to get weight out.
