Well that was fun! I spent like 4 hours and about 5 broken endmills learning something very basic. Pay attention to the temper on 6061 when you order. I had been ordering a few odds and end pieces from amazon since its fast free 2 day shipping. I didn't notice that i chose O temper 6061 this time. I thought it was just a really crappy gummy batch of aluminum. I ended up learning a lot about how to work through problematic material however and ended up getting my part milled.

I didnt know this and maybe it will help another noob.

6061 O Temper is very soft / anealed great for welding aluminum to endmills!
6061 T6 harder temper better and chips for milling
