A glasses like this mutes the vibrations that can occur in your rotating work when the work becomes thinner. They are quickly and easily mounted directly to the bed. As with the scale support, you press the damping wheels with a kind of scissors movement on the wood. The colour of the wheels has become slightly brown in the re-enhanced version. Furthermore, the wheels have been given interchangeable careers. Useful if they could get damaged once. Note: To assemble the glasses on your bed, you still need a clamp block. You can find the right clamp block here.
