Everyone,
I’m making raised panel doors using a vertical panel raising bit. I’m going to take several passes so I can remove a small amount of material each time. When using a vertical panel raising bit, do you take multiple passes by leaving the fence still and slowly raising the bit to its final height, or by keeping the bit fully raised and slowing moving the fence back until the bit it at its final depth?
Thanks.

If there's any curvature to the cut you're making, then you must raise the bit to the desired height and move the fence away from the panel in several passes.

I have wondered about this. Can you tell me why you move the fence instead of the bit?
Since the bit tapers outward at the bottom, you could raise it slightly between cuts but that presents another problem. You have to be sure that you have the fence in exactly the right position (front to back on the bit) before starting. I have found it easier to put the bit at full height and then bump the fence back slightly between cuts until the profile is right. It just seems to make getting the full profile the way you want easier.

Because there is always more to learn!
FR,
A third alternative is to make a jig of several 1/4" thick pieces of stock that you stack in front/around the bit....removing one piece after each pass. I can achieve the same outcome by using strips of 3/4,1/2,1/4 ply also. Just reset the feather board and your good to go.
Some discussion on that depth of cut, a critical variable.
