Default Re: Bucking frame rivets

I wouldn't be surprised if they punched the holes as long as it is in a controled way(jigged). In more current manufactureing processes holes are punched or drilled as pilot holes to give the correct quantity and location of all holes but these pilot holes are smaller than the final hole so as to get a more accurate fit during assembly. FoMoCo did everything they could to speed things up so they might have just taken the chance that they would be close enough to fit.

Today we start with the pilot holes then drill to fit Cleco fasteners to keep things aligned. Even with fair alignment the holes still have to be chased with a drill. Too bad Ford was so paraniod about keeping its business from prying eyes of the competion. We would have a lot more information about how things were actually done back then. Henry probably would have thought keeping track of it a waist of time anyway.

Body mounting holes,shock mountings, etc. were definitely pressed. You can tell by the way the metal is rounded on one side then sharper on the other.
