What? How could that possibly be?
If you brought a SCS clamp to our machine shop and wanted hexs machined into it.... it would cost at least $100...if not $200. You could easily have a couple hours labor in figuring, setting up, programming, and machining.
That is for doing a single SCS clamp.... now if you wanted to a couple thousand of them done it would be SUPER cheap.... Once a CNC is programmed and setup it would only take a few minutes per clamp.
