Time to assemble it properly.
I have now built my water table frame (heavy gauge 4x3 tube with 3x3 tubing legs). The frame must weigh close to 400lbs, even though my cut area is only 2x4. I am awaiting a metal nibbler to cut the base of the water table (sheet metal), it should be here tomorrow. I plan to weld the sheet metal base to the water table and add a 1" drain at the same time. I will coat the water bed interior with stove paint to help prevent rust.
I will position the cnc frame 1/2" above my water table frame, that way I can slide a full 4x8 piece of sheet metal in to the work area.
So, what do I use for the work material support? I have seen some fancy fins [?] that people use. I got to thinking, why can't I use regular nails protruding from the bottom of the water (maybe just nailed through a weighted piece of board) to hold my work up and flat. Why do we use metal fins when nails are very inexpensive? Am I missing something?
