I have mine arriving on monday as a cheap alternative to a sinar autoshutter for just now.

I have a friend who is a very accomplished furniture maker / french polisher who can I go to for the work. All I need to know is. Can I anlarge the hole in the shutter for the lens?

the hole is 2 inches I need it to be 3. From the sellers pics it appears to have enough wood around it to enlarge, but has anyone ever done this before and has it been a success?

Any help or advice here would be much appreciated, even better someone with a packard 3inch who would swap me straight ;D
