Oldie Vice

cults3d

Machinist Extraordinaire, This Old Tony recently put out a video showcasing a clever vice design that I wanted to recreate. The mechanism is remarkably 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. When the shaft is spun, it causes the clamps to advance in opposite directions at the same rate. This clever design ensures that your workpiece remains perfectly centered in the vice, regardless of the position of the clamps or the amount of area taken up. This model was created entirely within Fusion 360 using the This Old Tony Video as a reference point. If you watch the video, This Old Tony does an excellent job explaining how the Vice works and showcasing its unique mechanism that allows it to function smoothly. My model is not a replica; instead, I designed it from scratch with 3D printing in mind. Some Assembly Required This model comes in six different .stl files. The most challenging part of this model is the thread.stl file, which I discuss in greater detail later in the documentation. Assembly is relatively simple and requires no glue or additional materials unless you choose to use glue on some parts for improved functionality, which I highly recommend. Below are the assembly instructions embedded as a .pdf, but if that doesn't load for any reason, here's a step-by-step rundown: Thread both clamps and thread each clamp all the way down the thread in a back-and-forth motion on areas that give resistance to ensure smooth threading once fully assembled. Make sure they are both at the same distance from the middle to guarantee your clamped workpiece remains centered. Attach both thread ends, as the ends can become loose easily; it's recommended to apply a small amount of glue to secure them in place, but this is not necessary. If you do choose to use glue, be aware that it may become difficult to remove later without damaging the thread. Place the assembled thread into the bottom of the base, ensuring the clamps fit snugly into the grooves. Hold the thread down in the middle of the base with your finger and perform a full spin from completely closed jaws to completely open jaws to check for any issues with the thread or the bottom of the base. Make sure everything slides smoothly without any snags. Then, ensure the jaws are spaced evenly from the middle and click the top of the base into place to lock it securely in place. Depending on your printer's tolerances, the top may have a loose fit, but you can easily glue it into place for added rigidity.
