This was of great concern to the client, who kept a somewhat (understatement) close watch on things. When we rolled in the carcase on the two platform dollies, he asked if the felt pads were installed. “No, I’ll do that here,” I said. He allowed as how he’d really like to see how I did that. My helper left.
To my delight, a long phone call kept the client away while I brought in my HF 1 ton floor jack. I just cranked up one end, removed the temp blocks, and stuck on my precut felt adhesive pads. I lowered that end to the floor (the jack can be made to release very sloooooowly, hence quietly) and repeated at the other end. One trip to the truck with the jack, one with the platform dollies, and the mystery remains.
