I was just trying to explain that making a template out of copper then harden steel will take hours for the matching pair, that is of course if you have access to a lathe and milling machine which are CNC then you have to have a hydraulic press which is around 100+ ton and a power pack, to press the templates together, then you will have to weld the two sections with a spot welder, that's the basic shape next is the handbrake section and the brake shoe adjusters.
But if you can do that in a few hours great I'll call my engineer and tell him to stop work.
