You could very well be right Jeff, but the difference I perceive is that a 3 hp router will stall a lot sooner than a 3 hp shaper. The one shaper I used a lot was 3 phase, 3 hp 1 1/4" spindle. There was no perceptable slowdown when cutting 4" crown moulding in oak or cherry. I always figured that the any piece that got jammed would either become a missile or a fragmentation bomb.I keep hearing people talk about the shaper, but what is the difference in a shaper and table mounted router? Even the weakest router has more than enough power and speed to rip your finger off. Seems to me the danger is the same.
Whats different is the PERCEIVED danger.
I never had a mishap, so your comment about perception could be spot on. I know there are folks who are scared every time they use a tablesaw because they think kickbacks "just happen" and I consider their perception to be flawed.
