I couldn't find a handheld plasma cutting table with water table for sparks and slag, so I built my own. This video covers the design, material and the steps to build your own.





The Handheld CNC Plasma Cutter Video is COMING SOON, Subscribe and stay tuned. The hand plasma cutter table was the first thing I needed to build to be able to use the handheld CNC plasma cutter.

ALTERNATE WATER TABLE PAN SOLUTIONS

The cart that they recommend is available from Harbor Freight for only $80. It does have to be sealed as you're assembling it.

They added wave breaks that go into the bottom of the cart to prevent water from sloshing around as you move the cart.


The whole red frame gets screwed into the cart, which is odd, because it seems like that would make it more difficult to clean.

I don't see a provision for draining. I would add a drain valve to the cart. Could put a tank underneath the cart to drain the water into to clean the pan. If the tank is strong enough to withstand 3-5psi, air pressure can be used to raise the water back up into the pan.


6 gallons gives 1.5in of water and a 5.5in air space to minimize splashing. For handheld cutting, having the water a distance away from the workpiece is ideal to minimize splashing.


The cart is painted steel, not sure how long that will last with water sitting in the bottom. The water needs some anti-rust additive.


My 80/20 extrusion frame design could be built to fit the 36"x24" steel service cart in the same way.



STAINLESS STEEL WATER PANS DESIGNED FOR WASHER LEAK TRAYS


An inexpensive source for stainless pans suitable to be used as water tables are ones sold for washing machines. They are available in several different sizes.

IMPROVEMENTS


Replace the slats with 2in tall slats. The 1in tall slats are barely adequate. The plasma cutter can easily cut 1/2-3/4in into the slat, leaving the slats weak. To accommodate 2in tall slats, the slat supports need to go under the side extrusions.
