Check out plain ol bill's build, it is the best way to go.
I had intended to add a water table later but wish I had done it at build time now. Mainly because I have to change the design a bit. I will post to my build thread when I pick it back up in a week or two. The bladder/tank is done and works great. It drains fast with only 2psi. The tray is done too but I will need to finish up the slat holders and figure in some sort of screen to trap parts. Another five hours of welding/fitting and then a weekend installing. Vacation is getting in the way.
