Acrylic on LR2

I’m not home to look at speed and feed, and I was never able to get a glass look edge like on that video. I do have a single flute bit like that and I will try if this weekend if I have the time.
The results I get, you can see on my LR3 Build thread, which is very similar to yours.
If I’m doing a part that needs the sharp and glass looking edge, I usually wet sand it starting with 400 grit paper all the way up to 3000 grit and a very, very, very light flame polish with MAP gas.
