  1. That machining wasn't done very well !! Im very well experienced and it looks like he didn't even use coolant ! I'm also surprised it didn't come out of the vice you really want a mini rotary table with a internal expanding collet. Not to mention using a milling bit in a bloody Jacobs drill chuck !! You are meant to have that tool 600-700 rpm and drown in coolant otherwise it kills the tool and leaves that awful 2Micron surface finish. Done correctly with the correct feed and speed feeds it will leave at least 0.4micron surface finish( equal to a precision CNC turned or ground finish). That way you could blast it straight away rather than wet flatting it or brushing it. You want a precision square and flat face to ensure a perfect fit on the case back. I did notice a mark on the back where a machining mark was after it was blasted. Not good in my opinion but if your happy I'm happy for you.
