I just purchased a Rockwell horizontal mill, model number 21-120. It is about 425 miles away and was thinking about hauling the thing home myself. I need to weigh the options and get advice on how to set up the machine for transport. First thing the buyer says it weighs 500 lbs, does that sound about right? I have experience in trucking, loading, tying down loads and that sort of thing, I would like to know what one can do to the machine in particular to minimize damage. I have a single axle trailer to use. Thanks in advance. Bill.
