To save material on the cut off wheels (which will get some wear anyway), I cut in straight lines when working on the holes - like in the pic. With more thickness, the wheels will have some serious wear and get reduced in size quickly. That's why I tried cutting in straight lines and it worked out. I would use dremel sanding bits afterwards to rework the outlines of the holes. It's still quite some work.
David Floegel did some ozone style modding recently and he used a far quicker solution - round drill bits. But you'd have to have a drill bit with the proper diameter. Ah, Porter, you're already familliar with that project as you replied in the thread... Here's the link:
