Of course, I had to make it twice as hard for myself… I bolted two layers of the aluminium together onto an old control plate as a template so I could cut both plates at once. If there’s a next time it’ll be only one plate at a time.
Your post above got me looking for "ways" - if it can be done it's an "interesting" problem to work out.

I have found that a laminating knife can be used to cut aluminium (it'll take a few passes against a straight edge, but it might be a bit easier).
Not sure if it'll work to "cut" the rounded edges - but it might make it a bit easier for a bench grinder.
