I think it ' s pretty much impossible to achieve such tolerances and surface quality with just that , unless you machine it afterwards . That ' s almost airtight . Machining can also produce such accuracy but that shape would also be really problematic for rotating tools without rounding off the corners for smallest feasible tool radius . Custom made broaches could achieve the same result though . EDIT I mean EDM is a machining method also , was talking about more traditional methods of achieving the same result . <| sep |> This dude got my ebay banned and refused to help me out . Please , don ' t play yourself by helping him . <| sep |> That ' s when you increase your rate tenfold . <| sep |> Honestly ? Not really . I certainly don ' t feel as strongly about it as this , though . I think it ' s fun to see . I never said that generally drawing characters as other races was directly harmful to anyone , or that it looked bad aesthetically , I said this particular instance is not okay given the context of the character . EITHER WAY , harmful or not , I think it shouldn ' t happen .
