I have a GRS machine which I can use on smaller objects, but when I have work to do on something too long to go in the engravers ball, I just use my bench vice and use the hammer and hand chisel. I do some engraving on barrels of the muzzleloaders I make, and many of them are 42 to 48 inches long, so those are best done all with hand tools.
The floor plate on the magazine I did with the GRS, but the guard was cut by hand, and so was the socket on the Irish gun
