I think you are going to be disappointed in just how well the curtains will work containing plasma dust/smoke. We had two water tables at one time, and they worked fair. All our tables are down draft now and what a difference that made. we installed 5 HP turbine fans and ducted out through the roof and into outdoor containment systems. cutting full sheets pretty much formed an air dam but when we cut smaller sheets, we simply cover the open part of the table with a collection of 18 ga strips. We can cut all day with almost zero smoke/dust in the shop. for a small one-man shop, box in the side walls of your table add a simple suction fan and some HVAC would work great and be pretty cheap. You would be amazed how well it works.
