Worst shop purchase ever! I was looking for an attachment primarily to cut circles in my projects. In order to do this, you must remove 3 screws from the sliding plate and remove the edge runner. The screws were impossible to remove, and even with an "easy-out" they would not come out. So Now I have a tool with 3 stripped screws. Just for information, I also tried the front face screws, which also would no budge. I'm guessing that even though the instructions require their removal to add the swing pin, these screws have been chemically locked in.
