Setups to rout a wide and long area?
I have 21 - 2x6 SFS white incense cedar boards that are to be used as decorative cross-members on a long trellis.
These boards are all 36 inches long, identical in profile. I need to rout a square-U-shaped area in the 2" (actually 1 7/16 inches as milled) direction of each board, that's about 6 inches wide. This U-shaped-area of each board will fit "over" the top of the trellis, and I intend to screw each into the top of the trelllis with 2 - 1/4 inch x 6 inch exterior screws.
I'm thinking that I could rout all of these together in one session by clamping them all together (I do have enough long clamps to do this [new "on sale" purchase from Rockler!]). My question is about the best way to rout what would then be a U-shaped-area that's 6 inches wide and now 21 x 1 7/16 inches long (a little more than 30 inches).
I don't have a router table, but I do have a (new!) router. I don't have a table saw or any other nice tools like that - yet...
Any suggestions on setups would be most appreciated!
