I have a small craftsman table made for jigsaws and routers. Used it for the first time a few weeks ago with poor results. I needed to glue up a couple of boards for a book cabinet top and thought I would route the edges for a nice square face. Used a single piece fence and quickly realized the error in that thinking as my work left the infeed side of the fence...duh, that's why it came with a two piece (is it properly called a split fence?) fence. Learning curve was steep. Eventually (after 6 or 7 passes, thank goodness I was only using 2 1/2 foot stock!) I figured out to set the outfeed fence tangent to the bit and the infeed fence the depth of the desired cut...I did my best to square the two fences to one another by using the edge of the router table and a square...after jointing the two pieces, I layed them side by side the way I intended to glue them up only to find that the first and last couple of inches of each board pulled away from one another. I recut and recut taking great care to ensure square contact with both fences and got the same result time and time again. Where am I going wrong? Am I missing something fundamentally simple?
