Yep. I've used turret lathes, manual vertical and horizontal mills, 3-axis CNC vertical mills, and a couple of turning centers. I could really bang some stuff out on my old Warner-Swasey #3, once I had it all set up with tooling and stops. I loved running that old machine, and thought it was a lot more fun than the CNC's I programmed, setup, and ran.JerryVan wrote:Phonolair wrote:The beveled edge pointed out in the picture is correct and original.fran604g wrote:I know less than nothing as to the validity of any machining techniques that may have been employed in the manufacturing of the originals, however, one thing that immediately jumps out at me is the beveled edge on the left image. That could be a significant clue to the authenticity of the one in question.

If you compare different Concert reproducers you will see that this bevel runs from almost non existent to pronounced as in the picture of the Concert reproducer in question.
I would guess the difference in bevels is related to how the original machines were set up after tool changes or tool breakage.

Exactly. While they didn't have CNC equipment back then, they did have machines for making production runs. Turret lathes and automatic screw machines could turn out parts in very fast succession. As Larry mentions, the set-up of these machines was not 100% repeatable and was left somewhat to the set-up guy, who usually differed from the actual operator. Also, the product of one individual machine may vary slightly from the product of another, again due to small set-up variations.
