After looking a many pictures and reading many articles about building a router table I still am a bit at a loss as to what is really needed as opposed to "fluff" on a top and fence. I pretty much have the table roughly planned in my head as 2 3/4" pieces of 24"x32" MDF glued and laminated with either a T-track or combo track in front with 2 T-tracks for the fence to move back and forth. The confusion is with the fence set up. I see some fences attached to 2"x2" aluminum angle. If this is used, do I hack saw out an area in the middle for the bit and possibly a dust collection fitting? I have looked at the multi tracks from Rockler, but that set up is probably more than I need or want to spend. If I go with angle attached to split fence made of MDF, what is a reasonable T-track configuration on the fence itself? Thank you.
