Mike,

Yes it is the same with Aspire. What I did with one piece was I did a rough cut with 1/4 end mill and 1/4 ball nose. I then did a smooth cut with 1/8 ball nose bit. It took about an hour to cut with the 1/8 ball nose.

The first picture is after the 1/4 end mill and the second is after both of the ball nose bits. When I was done, I did not have to sand the material and it was smooth as you could want.
