Birdhunter,

Thank you for the encouragement. Yes, getting the code correct for this end was a challenge but I think it is correct now. For those of you anticipating do such a project please keep in mind there is a lot of work between scanning a piece and correcting the errors to get into solid works and then the G-Code for the CNC. CNCs are great but only as good as the code that goes in. Below is the completed receiver from the end work.

The one on the right is an original Winchester 21 receiver, the middle what was just milled, and the left one ready to mill.

In this picture you can see the difference in the amount of metal left in the middle one compared to the one on the original on the right. Should add a lot of strength.

I promised to show a picture of the re-designed hammer but forgot to attach. Here it is:
