This is one of the easiest tools to make, Find any flat piece of metal and drill two 1/4" holes the proper distance apart. Then take two 1/4-20 screws and grind down the threads so they fit in the hole in the clutch and bolt onto your piece of metal. I got lucky and found a piece of metal with the perfect distance apart holes in it already in my scrap bin. Here's a pic of one I made, I added a few bells and whistles.
Nice job! :msp_thumbup:
