How can I cut out 3 circles of 1/8" Aluminum circle

Hello Everyone,
I could use your help. I need to cut out 3 circles of 1/8" Aluminum. They are 7-1/2" diam. with a 2" hole in the center and a 4 or 6 hole bolt circle at 6-1/2". I have tried using a Scroll saw with Aluminum blades as well as other types of blades. They just snap. I'm feeding it about a 1/16" a min. (very slow). I have adjusted the tension without luck. My lathe won't swing that large. All I have at my disposal is a bench belt sander, 8" bench top drill press & Aluminum circle I can't afford to have it done. I need to come up with a way to get them cut myself. The parts are 7-1/2 square to start with. If I could figure out a way to cut the corners off I could use the belt sander to get it round. I thought about putting an end mill in the drill press and using a pin to rotate the part on. But I'm a little leery about doing that. The parts will have a 2" hole in them all said and done. I guess I could cut the corners off with a hack saw a little at a time until it is roughed out. But if someone has a better idea I'm all ears.
Thank you,
