Yes, you can use the router table as a jointer. There is a limitation that you cannot join a flat board face. But then again, you can do edge joining with ease. You will find the process of turning the table into a jointer quite simple. You will just need to do is, inserting the bit into the router and then raise the height of the bit unless it is higher than the thickness of the board. Next, you will have to adjust the fence till it gets even with the edge. However, there is a trick, and that is to offset one of the fences while bringing the other down a bit so you can create an offset. It will be great if you bring the fences closer to the bit without touching it so you can improve the cut’s quality and safety.
