I am having trouble adjusting the out feed table extension on my CMS Router Table. I get the edge closest to the table itself just below the table and then the back end goes out of whack. I've tried adjusting the 2 allen screws underneath the extension table, but it throws the front edge off, either up or down. I could use some ideas. Also, I've been trying to use my table as a jointer and I'm getting snipe on both ends of the board. I've watches many youtube presentations on using it as a jointer, and thought this would save me a lot of money by not buying a jointer. Please give me some suggestions.
