Happy Wife, happy life!

Did mine pretty much the same way but hemmed the ends and bent the metal at the sides to rest on the bottom structure and ‘sandwich ‘ it between the structure and the table.[/attachment]

Filled up with 230 gallons and ready to cut...

Table solution (per 75 gallons)
1/4lb Sodium Nitrite
1 Teaspoon Physan 20
1oz. Green Food Dye

Do you know how do you maintain the proper balance of chemicals? What do you check, Ph, or what? What do you add to adjust?

Thanks!

I do not, I'm just winging it for now. It would probably be a good idea to pick up some test strips and check, just not sure where the ph level should be, maybe I could use the Greencut specs (9-10) as a baseline? Because of the low cost I figured I could just change it out as often as needed, so far I've just added tap water to make up for evaporation loss and it works GREAT! My shop is clean and dust free and my table works great with the fluid level at about 1/2" - 3/8" below the steel.

With GreenCut you just use litmus paper to check ph. If it's too high, add water, if it's too low, add GreenCut. I'd imagine the same would be true for the solution Diamondback posted since water evaporation will just increase the concentration of sodium nitrite, making the solution more basic (add water to adjust). As the sodium nitrite gets consumed by cutting and water is added to top off, the concentration will go down and make the solution more neutral (add sodium nitrite and physan 20 to adjust).

I am not a chemist, but I watch a lot of Cody's Lab

I use the Dyanflux 360 water table treatment. Comes in granular form, in 100 lb. containers. Very happy with the performance. Same as others, maintain a ph > 10 by testing with litmus paper. For me, there was a huge price advantage by going with the Dyanflux vs. the Greencut.

GreenCut is definitely pricey, but it's got the most attractive MSDS.

Hey Dennis,

We’ve never made a Water Pan for a 5’x10’ Table like yours, but you could make one similar to the way we do pans on the 4’x8’.

Since it rests on the crossmembers of the legs, it doesn’t need to be too terribly strong. We use 14 Guage steel for the pan and it works great.

There’s a product called GreenCut that’s designed for Plasma Water Pans that is supposed to inhibit rusting. I read somewhere you can use Antifreeze also since it’s designed to inhibit rust as well.

It might be a challenge acquiring a single sheet of steel large enough to make the entire pan. You may need to make 2 halves and weld the seam.

Keep us posted on your progress!

Call if we can help with anything.

Here’s a pic of Go Fab CNC Table with a Water Pan and GreenCut.

Dave,
What are the dimensions of the water pans for the 4x8 tables? I remember seeing one at your shop the day that I picked up my table,

I know this is an older post wish I had seen it earlier. For anyones future reference, when I build the big Water tables for ( the last one I built was 40' X 100' for a big MG system) we use Coal Tar Epoxy. I was at a table I built in 2003 that is still running and never had a leak or rusted out.

I finally finished my water pan. I couldn't deal with the dust any longer. I still haven't decided what additive that i will add to the water to prevent rust.
