How to Build a Clean Box

some thoughts: for convenience (i.e comfort) perhaps a circular/tubular "box" isn't such a bad idea, but higher at the rear then towards the operator, then secure a plexiglass top. The stuff they sell at Home Depot goes by a different name, and it escapes me at the moment. Comes in sheets of different sizes. Holes placed at convenient spots in the sides/front of the tube as glove-holes. If I have the proper understanding, you'd have an inlet (for the gas supply) and outlet. Therefore the pressure of the entering gas would have to be sufficiently higher then the ability of gas to escape through the outlet. How would you control this? By using a smaller outlet then the inlet? Oi do I make any sense? In any event it seems you'd have to utilize filters for both ports. ____________________________________________________________________________________ We won't tell.
