That's exactly why I'm hesitating. For almost all the parts I make I screw the aluminium down enough for the router to spot/drill the holes then use those holes for screws to clamp it properly and stop things flying when it is cut out. With the aluminium bed it's more difficult since I would clearly have to make the holes align with the slots which isn't always possible... never straightforward is it!
