The shaper has auto-downfeed, I think I'm taking .003 per stroke. While I agree that the deeper the bit goes the more metal is removed, I see videos of similar shapers taking 1/2" cuts 3/8" deep per stroke. I am a novice on this machine, I thought I was well below the maximum cut per stroke.
I am no longer trying to use a vise for this job.
I agree the shaper can take some serious cuts. Those are usually taking a cut on one side of the tool, and the tool is ground to cut only from one side. Is your tool ground to take the cut from both sides, and the bottom? A neutral rake on any sides of the cut will take a lot more force to cut, and therefore will require that much more clamping on the table.
I would look into designing a fence to take the force from the rack, and prevent it from bending. The stronger the fence, the less pressure you will need on the clamps holding the rack.
