Just chuck a piece of 1.5" stock in the 3 or 4 jaw depending accuracy requirements. Face off the end square or taper depending on how you want it, drill or bore the hole and part off. I make various washers and spacers like that all the time. I have a dial indicator set up on my longitudinal feed so precise thickness is easy. Just add the thickness of you parting blade to the desired thickness of the washer/spacer, lock your carriage and part off. If you need a bevel on both sides, part off half way then make the bevel before completing the cut.
