Sioux Valve Seat Grinder Stone Dresser Stand & Dresser Machine - Complete Kit for Automotive Engine Repair & Maintenance

Nothing NOTHING aligns/moves/fits as it should.It's a nice start, after squaring and aligning every critical surface, I have a good stone trimmer.If you want good valve jobs and don't have a milling machine and the ability to set all the surfaces correctly to their reference, then stay away from this.
