The original idea and thread goes to JAMESPVILL 8/12/14. I thought the idea was super good so I decided to attempt to modify and install on my Grizzly G0602. Here is what I have so far. I hope to make some more improvements in the future but for right now everything works good. James had a good idea. For those who have not seen James' post the device is used when threading. It stops the lath in the same place every time so you don't have to precisely disengage the half nut.
