Got a couple quick shots but not very good since the shop is a complete mess right now. Hopefully you'll get the idea.
This first one shows the Plexiglas "wall" mounted to the side of the table and how high it is. As you can see, it barely clears the gantry. It goes around three sides. *Tip*, if you decide to go this route be sure to use flush-mount counter sunk screws in the plexi so the heads don't hit the cap head allen screws that hold the gantry uprights, nasty sound when they hit! (ask me how I know)
This second one shows my initial attempt at containing chips, it was probably about 75% successful. Could have been better if the end Plexiglas "wall" was taller but even then a lot of ships were going over the side walls. With a tall end wall I think you could probably contain 80-85% of the chips. Guessing though. I ended up cutting the end wall down flush with the sides to accommodate the retractable roller shade.
Here's a couple of the shade and how it's mounted. The aluminum bar on the gantry has a screw on each end that clamps the bar over the shade to secure it. The mounts for the shade are simply 1x2's mounted secure enough to resist the force of the spring in the shade. Seems pretty rube but it's amazing how well it works. Total cost, less than $20 for the shade all the rest was scraps. Once I get my shop back together I'll post some clearer pictures with it attached and extended. This is the best I could do right now.
