1/2" bolts for axels is way overkill, we've gotten away with 5/16", but usually we just use 3/8".

You also may need to add some standoffs to prevent the sides from crushing together. I might also suggest you make the flanges on the ends a bit longer to prevent it from buckiling in or twisting.

Lightening Holes? Delete them and see how much weight is actually saved. If it is on the order of 2-3 lbs. keep them, if it is 1-2 lbs.... is it really worth it? Personaly I'd only go after the dense stuff on the bot, like steel gears and sprockets, and leave the not-so-dense-stuff (like al) alone.
