ya I do use that guide. If you take a little bit of time to set it up for each surface, it's a godsend. I usually just hold whatever it is that i'm hinging in my hand and hold the guide as tight as i can with my thumb until the blade starts the cut, after that everything works just fine. The slot machine will jiggle the guide around a tiny bit side to side when first starting the cut, but it will keep it centered which is what really matters.


Also as vmsguy said, make sure you start the slot machine away from the work piece and then push it in one it is running.
