I made a copy of this one, mostly from the pictures. I don't know who to attribute it to, it was ten years ago from the internet. There might have been instructions on mounting the saw, it is for a Harbor Freight. I would assume one could figure it out for his particular saw. It works well, I still use it to this day. I had a trigger type switch adapted to a handle I made for it, but now I just have a toggle switch I use.
