We make trimming spinners from aluminum stock in small batches on our homemade mini CNC lathe. Then we assemble them by hand and test each one for spin. If you're looking to add stability to your trimming process, try one of these. They sit right on top of your work and allow you to keep fingers on your spinning object while you trim with your favorite tools -- an essential if you don't have a wheel chuck and/or for tall objects that want to teeter and sway while spinning. Plus, a helical texture on each face gives a nice little grip to your workpiece and your fingers so there's no slipping.
