thanks y'all for the feedback.
I've been cutting Al plate, bar, and rod w/ a 10" carpentry chop saw with excellent results. The carbide tip blade cuts fine through 4" rectangular bar. Some cuts start as plunge cut and I've had no problems.
My thinking is that it'd be quicker and cleaner to make the cut below and use a jig saw to remove "ramp". I need 8 each of these and could set jig for each angle/depth and get it done faster than scrolling each cut-out.
