Has anyone done this? I'd like to remove some material to lighten things up a bit. i am concerned that taking too much material away will increase the probability of warping.

My wood bed was a banana before I replaced it. I'd hate to have the aluminum start bending too. I was thinking of taking some large triangle chunks out so that the bed resembles the Union Jack. I could easily do this with the tools I have at home.

My other thought would be to have a bunch of hexes machined into it but that would be a bit $$$.
