I have worked for both AB, a couple times as well as CBI but never used engine drives with them, AB had truckloads of 6 and 8 packs, 600A CV machines, its been some time ago, LN23's I believe?? 202 and 203 innershield. If anyone has been in Miami you can see the space frame on the now Wachovia bank, I was on that, welded connections to the building and splices joining the sections together. A guy named Dave Black was from AWS was down there on occasion, this was when innershield was really making inroads in the erection biz. All full pen, back gouge stuff. Was a strange deal, fabricator really had the bevels on wrong side of one side only.
