I'm planning on going to Lowe's after work today to buy a few more things. Namely: a ceiling tile to build on, sandpaper (80, 220, and 360 grit per the manual), a big metal ruler/straight edge, sanding block(s) (T-bar), wood glue, a square or two, playground sand (for plastic baggie weights), and 3M #77 spray adhesive (for attaching the sandpaper to the sanding blocks).

If anyone can think of anything I've missed, please let me know!

Either way, I'm not going to start building until tomorrow at the earliest. I'm going to take the rolled plans in to work with me and use our drafting plotter and scanner to scan in the plans. That way I'll have a digital, full size, copy of the plans if I ever need to print them out again in the future.
