I have been following several table builds and wanted to post on old YouTube video on my water table.

This table is now 15 years old and I have kept the now defunct Plasma Quench from Koal industries in it continuously.

The table was built out of 10 ga. HRS and is basically a box w/i a box. I have 3" of fall over a 9' run. The sump end is twelve inches wide. Right now I have +/- 250 gallons in the tank,
I have a 2" drain with a ball valve. I've never drained it. We keep the table drained to reduced evaporation. I keep roughly 8" of water in the tank and this allows me to completely cover an material that I'm cutting.

Here's a video of the table filling up.https://www.youtube.com/watch?v=0wZXw4Ucl14

Here's a sketch showing an elevation on the tank. I have a 1" gap at the bottom. The supply valve is 1/2" . The dump valve is 1" Attachment 270000

The only improvements I would do over are to build in bigger. This is table is a 5x10 and I would go for a 6x12 next time.

Thanks,

Tom
