Now I just need to locate a source for the pipe, and check prices on it..
the MDF looks like it will be about $22 for a 4X8 sheet.
Looking for info on drilling & tapping holes in MDF though, if anyone can help. I will also post this question as its own topic.

Be careful with larger taps when backing them out as they can cause splits in the MDF. I usually mount a clamp accross the mdf to keep it from expanding. Also with the small taps ( 10-32 and smaller), you can drill the holes and then put the tap in the drill, makes a much faster job than hand twisting the tap in.
