northeastern Ohio | How would you fab the following part (see picture below)? It is 3/8" 6061 aluminum, 6" in diameter, with a 2.25" hole in the center, and six 1/2" holes. The six 1/2" holes are not a problem for me. However, what would you use to cut the overall circle and the circle in the center? I took it to a local fab shop and they quoted me $110. I do not have a lathe, but $110 would make a good downpayment on one. The local fab shop said that they would use some sort of router to do it, but they didn't go into any details. Suggestions please!
