I decided I wanted to add some type of clamping to the jig. I saw several pictures of Bill Churches jig on WestCoast Piet and decided to use his method. I cut strips of sheet metal on my shear and bent them on my sheetmetal brake after drilling a 3/8 hole for the clamp to slip over the all-thread which I attached to the jig with T-nuts on the back side of the jig board. I used nylon wing nuts I bought off Ebay to use to apply pressure to the clamp. So far it seems to work well.
