I am relatively new to woodworking and have a Delta Cabinet Saw, 4 inch jointer, and a Delta 121/2 inch planer. Do I need to edge joint a board, or can I use my table saw to get a single reference clean straight edge and then run it through the planer. I realize that I may need to make multiple thin cuts in the process, but it seems that my table saw fence can act as a long reference surface to get two parallel edges and that multiple shallow passes through the planer, should provide a board with straight edges, parallel surfaces with true 90 degree angles on each edge.
Since my jointer is very narrow, it seems like the method I have described should work. What am I missing?
