An easy way to get that inner sleeve off is hold it parallel against the jaws on that vice that it's sitting on with the sleeve resting on the jaws and hit it up and down the inner sleeve with a ball peen hammer. Then rotate and keep hitting it with the hammer. It'll expand the sleeve and it'll slide right off by hand. Just make sure the vice jaws are opened to to about half-75% the diameter of the sleeve. Trust me, once you do it that way, you'll never attempt to cut the sleeve off again. It's THAT easy.
