I’m making progress on the rifle I’m building, however, I have a sequencing question. As I understand, the typical sequence saves the metal engraving and metal finishing until near the end.  I’m still working to shape my pattern stock, which will be sent out to a duplicator to have it reproduced in a nice piece of walnut.  As I’m working on the pattern stock, I have a window of time where I could send the metal (floorplate, trigger guard, grip cap, buttplate) out for engraving.  If I did that the parts would already be engraved before final fitting into the final stock. Would that be a problem?  I don’t imagine any rough treatment of the parts during final fitting, so I would not expect the engraving to be damaged.  I would reserve the final metal finishing (blueing, color case, etc.) would come at the very end.  So again, should I expect any problems if I have the metal engraved now?  I welcome any input.
