I bought this to be part of a process device in our workshop. It is part of our belt sander to allow us to shape the bottom arc of a product. I was blown away at the quality of the product, when I consider the cost I was impressed with the quality, I didn't expect much and was very impressed with the delivered product.
We mounted it on an aluminum plate base with a square bar that keys the slide unit into the machine, we made an aluminum cover to keep out the grinding dust and then a product plate to hold the product in place on the top and then can use the slide to move the product into the grinding belt. You can see the little blue slider under the aluminum cover.
