A simple bolt and spring at the top of the Floating holder to provide up bias against the weight works fine. I mounted a small block with a through (clearance hole) on the Z plate and tapped the top of my floating torch holder. With a long bolt and a spring between the head of the bolt and the small block it wants to lift the bolt Up. When screwed into the topof the floating holder it pulls the holder up. The tightness of the bolt determines the uplift force. I can dial in whatever amount I need. For really thin material the table slat setup needs to be closer spaced to provide more support under the material. |
