I put together a video of how I make a machinist Jack and I am making a pair of them to be given away next Monday. They are a simple design using 7/8" hex stock that I drill and tap for a 3/8" bolt. I also add a simple taper to the top and face off the head of the bolt for a nice flat surface. If you want a chance to win the pair of jacks just watch the video, subscribe and leave a comment. I will pick a winner from the comments next Monday.
