Oldie Vice

myminifactory

Machinist Extraordinaire, This Old Tony recently put out a video on a cool vice design that I wanted to recreate. It is mechanically very simple and relies on a long rod with right-hand threads (clockwise) on one side and left-hand threads (counter-clockwise) on the other side. So, when the shaft is spun it causes the clamps to advance in opposite directions and at the same rate. This mechanism means that your workpiece is always dead center in the vice, and no matter the position of the clamps the vice takes up the same amount of area. I recently had a great idea for a new vice design after watching a video by Machinist Extraordinaire, This Old Tony. The video showcased a very simple yet effective mechanism that I wanted to replicate. The design relies on a long rod with threads that run in opposite directions on each side, causing the clamps to move in synchrony when the shaft is turned. This new vice design was created entirely using Fusion 360 and serves as a great example of how to apply the principles of This Old Tony's video in a 3D printed model. By watching the video, you can see exactly how the vice works and understand the unique mechanism that makes it functional. My design is not a direct copy, but rather an original creation designed from scratch for 3D printing. Assembly of this new vice design requires some effort, but the payoff is well worth it. The model comes in six different STL files, each with its own challenges. The most difficult part to assemble is the thread.stl file, which I explain in more detail later in the documentation. However, assembly itself is relatively simple and does not require any glue or additional materials unless you choose to use some for added functionality. Below are the assembly instructions embedded as a PDF, but if that doesn't load for whatever reason, here's a brief rundown of how to assemble the vice: 1. Thread both clamps and attach them all the way down the thread in a back-and-forth motion, making sure they're smooth and evenly spaced. 2. Attach both thread ends, applying a small amount of glue if desired to keep them secure but not too tight. 3. Place the assembled thread into the bottom of the base, ensuring that the clamps are seated properly in their grooves. Hold the thread down with your finger and spin the jaws from completely closed to open to test for any snags or issues. Depending on your printer's tolerances, the top may have a loose fit, but it can be easily glued into place for added rigidity.
