I am wanting to use my router table to create a channel in the back of an artist easel I am building. This allows the easel to adjust to different size frames. The channel is a 1/2" wide by 4' long cutout centered in a 3/4 x 2-1/2 by 5' peice of stock. In the past I have attempted to use a 1/4" straight cutting bit removing 1/8" of material at eaxch pass with mixed (and unpredictable) results.
My question is this: Is there a better way to go than the straight cutting bit. Is an Onserud bit the right (better) bit for this operation.
Thanks (again) in advance, Bernie.
