So we have the water pan complete. This is where we have had some major indecision. We asked several questions:
Do we want to leave it just as it is?
Do we want a sump / fluid reservoir?
If we have a sump how are we going to drain / fill the table?
Is a reservoir really necessary?
We debated for several days trying to decided. In the beginning we had decided to use two 55 gallon drums as our sump tank / reservoir. That plan went out of favor then came back in. We want to use air pressure to control fluid movement but have heard the poly drums will handle the pressure and we have heard they will not.
The drum plan came back into play and we have not come to an agreement on how the fluid will be moved to and from the table we did build the drum holder.
We had several constraints which made engineering this drum holder a little tricky. It had to hold the weight of 110 gallons of fluid. It had to be on wheels so that we could remove it if we wanted. It had to to fit under the table, which was barely wide and tall enough to fit the barrels without the mobile holder.
Here is what we came up with:
We used 5 in casters from Harbor freight that were rated at 330lbs each. 4 wheels is most likely more than we need but we would rather over engineer now than fix it later.
The Frame is 2x2 x¼ angle. We used 1.5 inch square tubes .120 wall for the risers off the base.
1 x 2 rectangle tube forms the risers off the wheel plates.
1.5 x 1/8 flat stock for the belly supports.
The height of the drums was almost too high as it was so we had to fit the wheels in the space of the curve to keep the overall height as low as possible.
The width was also a problem so we had to tuck them in as much as possible.
We have about 1 inch of ground clearance.
The drums fit nice and snug in the holder as well as under the table.
The water table will hold 70 gallons aprox. So we should be able to use the high and low bungs to move the fluid and the air gap will work out and not affect our capacity.
