MORE UPDATES!!! Okay, threw out the aluminum idea and went and spent more money on .25" ACRYLIC. That's right people, I'm not f*cking around. It's even more rigid than with that steel plate and I bought enough to do the entire thing and then some. Looks kinda like a razor or something. Anyway, if you ever need to drill acrylic, never use a sharp bit. Use dullest POS you have, it'll work much better as I unfortunately found out. Anyway, back to work.
