Watertable depth?

[DeviousMW]

I have a 4x4 table made out of 80/20 3030. I'd like to add a water
table to it but I am concerned about the weight and how much depth
do I need. Would 1 or 2 inches of water help?

What do most of you make you water table out of? Galvinized sheet metal?

How do you regalvanize the welded corners so they dont rust?

I am hoping to bolt the water tray to the xaxis where the slat holders are
currently bolted to and then run a bottom support down the middle
of the tray underneath.

Thanks,
Mike

Mike:

Most people are making the water table out of mild steel and putting a rust inhibitor in the water.As far as how deep it depends on how thick you want to cut.Usually water tables are 6-7" deep but I have seen some only 2" for doing thin sheet metal.As far as touching up welds on gal there is a product that you can spry on to re-galvanize.

Sir,

We had a customer on the west coast who cut very thin material; his water table was only about 2" deep and it served him well.

As a matter of fact. in order to minimize warping on his thin stuff, he had the water level such that his workpiece was just barely covered by the water. When the torch was turned on, the air/gas blew away the water just in the vicinity of the torch tip, and the result was that the remaining water carried away the cut heat very well with no warping.

I built my water table out of 16ga stainless sheet. There was a thread last week discussing water table depth. 1" or 2" of water would definitely be better than none at all...

As pointed out above the water is quite effective if close to (or very slightly above) the top surface of the material being cut.

To be most effective for dust collection, position your slats inside the water tray, then water level can be raised to the top of the slats or top of material being cut.

Various water depths are used by builders.

My system works well. It is 4" deep with the slats submerged 2" into the water, with the slat top surface normally level with the water surface.
