I did a bunch of work getting the water pan set. Precision Plasma the manufacture of the table provided plans for fabricating the water table. I modified the plans a little.
I went with 1/8 plate formed into a pan using their dimensions to fit the table. Their plans included an integrated slat holder that was plasma cut in to the plate then a 120 degree bend used to form a lip. No one in my area could plasma cut a sheet over 4 x 8 nor could they bend a 120 bend on top of the 180 bend. So I opted to use their alternate design.
I used 1.5 x 1.5 angle welded along the edge with 3/16 gaps.
They specified 3.5 in 1/8 flat stock for the supports. 3.5 inch flat stock is crazy expensive at almost $40 a stick and i needed 10 for the table. I opted for 2.5 in which was a quarter of the price.
To make this work I added a 1/2 support to raise the slats up off the floor of the pan and help with fluid flow. I also opted to have the slats sit 1/2 below the rim of the pan.
I will fill the table 2.5 inches deep and have 1/2 gap between the fluid and the part being cut. I think this will workout ok but its the first time I have done this so we will see.
Their design did not call for a center support rib but I added one and it made a big difference.
The slats slip in nice and easy but lock in once in place and I do not get any movement.
Yes the steel in the drawing is brand new, my steel supplier delivered some very rusty stock and they did not have enough. I hate cleaning brand new things!
I put more photos on the build website than I could post here: I did a bunch of work getting the water pan set. Precision Plasma the manufacture of the table provided plans for fabricating the water table. I modified the plans a little.
