When drilling with the hole saw, I've never seen the need to drill a pilot hole. The drill bit in the arbor is the pilot bit, which drills through cleanly before the hole saw works its magic.
Great pictures.
I only did that because I thought the hole saw bit might have a tendency to be drawn into the acrylic. I have some other drill bits that do this and didn't want the saw part to come down into the acrylic hard. Probably overkill but you know I'm not one to do things the simple way right? :lol:
