Just got back into town and saw your questions. I had taken off my water cooled spindle and mounted a Bosch 1617 and had my speed set at 18,000. I was using a 1/2" diameter 2 flute Whiteside straight bit (1072). The bit has a 2" cutting length which is why I went to a router with a 1/2" shank instea...

While making a 1-1/2" profile cut with a half inch bit my router will stall and then my HD510 will jump out of the profile cut 1/4" or so tearing into the side of the cut. I'm only making 3/16" depth passes so I'm not sure what the issue is. Any ideas?
