FILENAMES: smoke-grinder.jpg DESCRIPTION: This is a rendering of a "smoke grinder". Posted by Van Baker . The following description was provided: ================================================================ Quick sketch of a 'smoke grinder' - handle left off for clarity. The handle would be a bar (simple or fancy as you like) attaching to the two sliders with screws in the noted holes, and extending in one direction for clearance. One way to make these is to use clear plastic for the body, shows the moving parts better.
