I think the rating for the Porter Cable router is five steps producing speeds of 10,000 - 23,000 rpm. I have done some web searching and I can't find any information of what the approximate speeds are for step 1, step 2, and so on. I suspect that step 1 is around the 10,000 area and step 5 the 23,000 but I just don't have a feel for the speeds. I know they are approximates and change with loading; but I would really like to know the ballparks so that when it is expecting 12,000 for one and 14,000 for the next bit, I can figure out if I should change the speed.
Does anyone out there have an informed guess or better?
Thanks!
