Just catching up with this thread. I'm probably 'teaching Granny' here but a riving knife is only really needed for planking or sawing along the length of timber to open up the cut to stop the wood 'pinching' on the blade. Regarding safety, the two most important are the side blocks, to prevent the blade catching the bed or table sides should it become unbalanced (wobble) and a 'free' pulley and lever where you can move the belt from the driven pulley to the free pulley from your working position should you need to stop the blade. On acquisition of such a saw the first thing I would do before attempting to power it up would be to take the blade to my local saw doctor, at the local sawmill, and have him balance, sharpen and test it for cracks.
