Here's a good article on lathe speed. - http://blog.woodturnerscatalog.com/2012/08/safe-wood-lathe-speeds/ When using the Simple Shear Cutting Finisher if you're experiencing tearout the tool should be rotated about its axis (like twisting a motorcycle throttle) until it's making a shearing cut. Usually that rotation is around 35° but varies depending on the wood being turned. So again my suggestion would be increased spindle speed and rotate the tool about its axis more and I bet you'll find much better results.

Usually when tearout is experienced it has to do with speed more than anything. You did not say what size your work piece  is other then it's small so I will assume it's 1 inch for the purpose of this discussion. That being the case the spindle speed for roughing should be at least 2000 RPM and quickly increase when the block is a cylinder. Finishing should normally as fast as your lathe will go. Technically speaking the finishing speed should be 9000 rpm but wood lathes don't go that fast.
