Not worth writing an article about but worth seeing. Here is a photo post of my vise stop I made. It is handy if you need to perform repeated operations on identical parts. Initially when I decided I needed this I did not have a clear mental image of how I wanted to design mine so I went out on the web and looked at a bunch of pictures. I found some common features I liked and incorporated them into my design.
Mine is flexible enough I can use it with a variety of setups.
