Looks like you've got some great responses. I suppose I might as well chime in. The first thing that I noticed, was that you drilled mounting holes for the T-nuts, so you could mount the plate to your table. The use of toe clamps would eliminate the need for that. The second thing I noticed was no coolant. If you use an oil based coolant in a mister, your feedrate would definitely improve, surface finish would improve, and tool life would improve. I can see your endmill is getting coated with aluminum. After that happens (as I'm sure your aware) it's all downhill. Coolant would remedy that. DEFINITELY get an oil-based coolant. Next thing would be to make up a jig, as everybody has stated. From reading vmax's post, I can tell he's made a few. I have to agree with his method for the most part, as I've made a few myself. I do disagree with using coated cutters for aluminum, but as they say..to each his own. I would definitely use the hole in the part to clamp it down on a plate, thus enabling you to cut all the way through the part. That would get rid of another needless (and dangerous) process. Next is the use of the tumbler. Have you thought about purchasing a sand blaster? They can be purchased relatively cheap, and you can blast hundreds of parts in the time the tumbler takes to do a few. It would also deburr the parts, and leave a nice, even, matte finish, ready to be anodized. How many can you get in the tumbler? Less than 10? You could accomplish that in 5 minutes. Anodizing does not take well to sharp edges, as I'm sure your aware. If your having a problem there, you could put a fillet around the part. It's and extra step, and that means more time, but if it solves a problem you might be having, it would be worth it. A small radius makes everything look much more professional and pleasing to the eye, anyhow.
Ed had a very good piece of advice on buying a machine. I would have to agree 100%. You would most likely have to buy or make a phase converter, but that's not a big deal at all. If your dead-set in buying a smaller mill, take a look at Novakon. You might find something there much cheaper than 10K+.
