My son Jake and I totally stripped and re riveted a complete Ford Marmon Herrington 3A chassis with the exception of a couple of spring hangers. Because many of the rivets were flogged out and loose we drilled them all out to 7/16 and replaced them with the slightly bigger rivets. It took a week and involved making/adapting tools and jacks to load sufficient pressure especially in tight awkward spaces in and around cross members. I of course did all the hard work of holding the oxy and heating up the rivets. Jake just had to hammer them down and shape them. I didn't have the advantage of a suitable air hammer but I did have enthusiastic youth. Like Mike said, b****r of a job but the way Ford chassis' rust it was the only way to rebuild a good one.
