    I have been using a Unimat PC for about 10 years - nice little machine. A while back, it stopped running - blew the fuse as soon as I turned it on. I localized the fault to the speed/direction...

    At a quick glance, the tailstock appears to be for a round or tubular bed (the SD 200?) not the one that you bought which appears to have a single rectangular way.
