I am looking for some advice on routing raised panels. I just picked up my first raised panel bit and I have to admit, I am a little intimidated after trying a piece of scrap. I routed across the end of a board and it did not feel safe. I then tried to make several passes raising the bit a little each time but there is a built-in back cutter attachment and it looks like that approach defeats the purpose of the back cutter. Should I remove the back cutter and add it just before the final pass or keep the bit at the finished height and move the fence back a little with each pass? What is the right way to do this safely, especially across the ends? I guess I will have the same issue with the stile and rail bits. I've never used bits this large and I do not feel safe. Any help is greatly appreciated.
