I have a jig for routing an ellipse but I am wondering what kind of bit to use. Do I use just a straight bit or should I get a spiral bit? Any suggestions?
I prefer spiral but as to up or down cut, that will depend on your material. Up cut pulls so your bottom surface would be your "good" surface. A regular or shearcut bit would also work but spirals give a better edge for me.
I bought the Rockler jig. It looks very easy to use. I will get a chance to use it this weekend so I will report on my experiences with it. I am using it to make a sign for one of my staff at work. I am just starting out making signs so everything is a new experience.
Good thing today is payday. I need to go buy a spiral bit.
