Hi, this is a framebuilder thread yet I think would be appropriate to ask about building a pannier rack ( or is there another dedicated thread on this somewhere?). Looking for an operational term in metalworking to describe how many rack manufacturers terminate their racks at the point where they are designed to meet and attach to the frame. It looks to me like the alloy rod end is heated, then fed into a stamping machine that simultaneously compresses the rod to a flat shape on both sides while punching a hole through it. Is there a name given to this operation?
