    Good question! Generally 1/4" 6061 alloy aluminum is good as a baseplate for a small projector. It allows for a rigid and (hopefully) flat baseplate along with limited thermal flexing and it also makes a good heatsink. I don't have a local supplier of aluminum myself so I usually buy my aluminum off of ebay or from my friend who owns a local machine shop.

    Here is a decent seller... http://cgi.ebay.com/1-4-250-Aluminum...item35a9123c1b

    Flexes too much for optical use. 1/4" should be your minimum for anything optical.

    There is a place here in Orlando called Skycraft. They are a surplus store. They have a website and sell mail order, but it wouldn't be cost effective after shipping costs. Check your area for surplus stores too. They are freat for everything you need to build a projector.
