To all you out there, no offense for haggling, but truthfully, Gunsmiths are a for the most part, really underpaid, any time I have to do machine work, I know I am taking the risk of doing permanent damage to a firearm, and I expect to be responsible for it if I do, I do evaluate the firearm and how much the piece of it that I am going to machine is worth and the difficulty of the job, I am not going to do a porting job on a 10,000 dollar Perazzi, leave that to the guys like Briley who not only specialize, but have the type of insurance to cover it.
Next dovetail cutting is a kind of art, if your going for the friction fit, a Rear Bomar melt, includes dove tailing, but is held in by screws, front sight friction fit or rear sight for that matter, can be difficult, because each sight is slightly different, you cannot set it and forget it, you have to measure the sight and the cut, even with the best parts. I have had to repair factory front dovetails because the sight was walking, the easiest fix, if there is enough room, is to drill through the side of the sight dovetail into the frame and put a set screw through both, that is never walking again. Pretty much, dove tails are rarely used, outside the gun world. So a master Machinist, may have never had to cut one.
