These are some really cool up close pics . I've seen the gearbox direct connect to the blade and not /Plus those blade diameters answer a couple questions I had.. Can I get some pics of the swing handle or the mechanism that swings the blade and locks it in the vertical and horizontal position. I was thinking about two semi circles one with a cut out and a the other with a stud in it and when I swing the blade into any position between vertical (90 degrees) and horizontal (180 degrees) I can stop the the travel with a turn of a handle . I also like the side to side set works that allow you to move over a preset amount . over and over. so any pics or explanation of that is also appreciated.
