Construction Questions for Oomlout's "How to Make a Three Axis CNC Machine (Cheaply and Easily)"

Apologies if this is in the wrong area, but I am in the middle of constructing Oomlout's CNC machine and was hoping someone could answer my questions.

It's not clear when cutting the Top Beam and Bottom Beam if the 1/4" holes are to be through holes or are .125" channels like the other 1/4" channels.

From the pictures it looks like the top is a through hole channel, but the bottom couldn't be.  The bottom says "0.000" where the other channels say ".125", so I don't know if that's a typo, I can't figure it out.  Having never built this before and the channels are not yet cut in the shot of the cutout pieces here  it's impossible for me to figure out.

Getting very eager to finishing this thing, I can't wait to start cutting things!

Please help!!!

. There is a lot more info in the PDFs and other files. See step 5. What you need to know may be in there.
