Well this was a personal project at a shop I work at, so I don't have any pricing knowledge really. I did burn up several sides to the inserts I used, so that's like $60 in tools, took about an hour of messing around with it. I bet a shop with more experience with hard metal and big stuff would charge you $100-200 to face it, depends on shop rate and stuff.

If it's hardened, you'll want carbide tooling, which can be spendy if you break it. A shell/face mill like was used here works great.

Personally, I probably would have tried to fly cut this with a carbide tool for that extra fancy surface finish!

I would charge $75 or so to do this if I like you. But I only machine as a hobby, and have no idea of going rates for walk-ins.

It said 127lbs on the casting, just about all I could do to pick it up.

Good call. Gotta lift it by the horn.
