Send the shutter and board on down to me Mark and I'll do it for you.
Cost - One snickers bar.

Dremel tools are a huge scam. They were designed for jewelers and model makers doing small work. Like tiny.
Money is best spent on a 1/2 round bastard mill file. It will remove material faster than the Dremel and you will have much more control. Also, the file is the better tool, so long as you also buy a file card or brush to clean the thing off. And there are no silly collets to deal with.
Added that the file is a better green solution. The only energy it consumes are your calories. No plastics. 100% recyclable.
Ditto on the file, and it's a good idea to scribe the new opening size on the board prior to cutting so you know when to quit.
I just enlarged a Shen-Hao aluminum Technika style Copal 0 board to a 46mm hole with a half-round file.
First I inscribed a 35mm hole (Copal 0) on some paper. Then I lined that up underneath the actual hole in the board. Then, using the centre of the circle drawn on the paper, I inscribed the outline of the larger hole on the board.
The filing might seem a bit masochistic, but I only had the one board and no other tools. It actually only took about 15mins, far from sensitive family ears....
Another vote for half round file, either a mill or a mill/bastard cut and a bit of patience.
Be careful of anything rotating inside the hole that is very nearly the size of the existing hole. If it binds and you are hand holding it, the board will do a number on whatever is holding it, preferably not your hands, but you're not using a drill press anyway so that's a moot point.
Ditto #3 on the file ... get a good 1/2 round that approximates the arc of the size hole you're expanding. The results will be much more even and controllable than with a power grinder ... and ... at least in my experience ... it's just as fast. The 1/2 rounds that I use actually say they're made for wood but they work well with aluminum also.
I handhold the board, do 1/4 turns with 1, 2, or 3 strokes per rotation doing a long sliding stroke across 1/4 of the circle ... I go slow as I approach the correct diameter (it's very easy to get impatient and get it too big ... been there, done that ... several times) ... I check the new hole against a circle on a card or piece of cardboard so I can correct any lopsidedness (I'm sure that's not a word ... but you know what I mean) ... you can make it pretty precise just eyeballing it.
Wow! Thanks again, everyone!
Matt, I think I found a Snickers bar under my six year old's bed... I'll send you an email.

So that must be why Matthew is willing to work for Snickers!Originally Posted by Robbie Shymanski

Whats in back of you is the past and whats in front of you is the future now in the middle you have choices to make for yourself:
LOL...Good one.So that must be why Matthew is willing to work for Snickers!
Your secret's out, Matt.
