Step 2Circle cutting
Use your circle cutter on some paper first to figure out what size you want your eyes to be.
After sizing, get your roll of masking tape and cut 4 circles that are the same size out of it (Use a wide masking tape for this. I cut my circles right on the roll).
If you are making your eyes out of plexiglass, put the 2 circles facing back each other on each side of the plexiglass. Then score around the circles (I scored straight lines many times and broke off the scored parts. If you know how to score and punch out a circle from plexiglass, I'd like to know how to do that.) Use the dremel tool to grind down the plexiglass until you get to your masking tape. The masking tape acts as both a guide and a scratch protector. The plexiglass will smell and melt a little when you grind it, I suggest good ventilation.
If you are making your eyes with glasses, make sure you label each lens (Left and Right) and possibly (before you pop them out of the glasses) what side is up (I kind of wish I did the second part on mine). Put your masking tape circles on your lenses (one circle on each side) and grind your glasses down with your Dremel. The glasses will not smell when you grind them, but they will produce a lot of dust.

Most important first - DON'T breathe in glass dust!
This is something that's not commonly understood as a danger / risk. But as an example, i remember a 'warning' sent to me by an archaeologist who used a grinder on a dig without a mask, just once, and shortened his life-span by about 10 years. He was cutting rock, but glass is the same thing (silica) and it's when tiny shards are created that it becomes a problem. If anyone would like more info, let me know, or look up 'silicosis'.
If you're getting fumes from the plastic of any kind (incl. perspex / plexiglass) then you're cutting it too fast. Try using a hand saw to cut a piece of roughly the right size and then sand it down to the perfect shape. (PS: depending on the plastic, the fumes from melting it can be very toxic.)
I know i sound like a nanny about the dangers, but it's the reality of what you're dealing with.
