Setting Up for Accurate Raised Panel Cutting
From the original questioner:
No guide bearing on the cutter.
From contributor S:
I would get one for that size cutter. Then you will be good to go.
From contributor J:
It's not clear whether you are getting a "dip" in the horizontal or vertical plane. If itís the former, a continuous fence spanning the gap should cure it. If itís the latter, are you using a power feed or a featherboard just beyond the cutting circle? A powerfeed with belts rather than rollers may work best for narrow panels.
From contributor F:
I put a zero clearance board (1/4" MDF) in front of the cutters and fence. To set up, I move the fence forward past the cutters and clamp the clearance board to the fence. I then move the fence back into the desired position while the cutters cut through the clearance board.
From contributor C:
Either way will work. A power feeder is a must. We take in two passes.
From contributor M:
The easy fix is a bearing as mentioned above. It won't allow your panel to dip into the cutter.
From contributor T:
You spoke of a large panel being shaped; be sure that the entire horizontal base is supporting your project material. A zero clearance support is important to bridge the space between the infeed and outfeed vertical fences. Two featherboards should also be installed; one at each toe of the infeed and outfeed fences, pressing lightly downward on the material.
Most of all, have the feeder downward pressure (on the work) just light enough only pulling the material through without any pressure change after the material passes the featherboard. Any sudden pressure change will cause the material to dip at the cutter. These methods have worked well for my shop.
