I guess every Sherline owner knows Luiz Ally (Tryally) and his videos on YouTube including the one about his slim vise which looks like an excellent solution for holding small and thin objects.
If you are interested in building such vise you may find the attached file useful.
it’s a SketchUp model I’ve designed with minor modifications from the original, what I was able to see on the video. I have not built it yet and not sure if I will go for the exact solution or to something similar based on a tool plate, we’ll see.
So for now you are welcome to download the file and feedback if you have any comments, and I repeat, I have not built it yet so it may contain errors.
Design credits to Luiz of course.
