And I would add for folks that are going to fabricate a piece: Don't overlook *wood* as a possible material. Wood comes in a zillion types (at a woodworker's supply store), and some types have very

Hi Ray, I see the "Files" section in the menu on the left side of the page, when looking at this page: https://groups.io/g/TekScopes/topics Here's a link to the "collet" search, which then shows a
