I have a problem and I thought this might be the place to ask....

We have a cnc wet grinder, and are always fighting the coolant splashing over the sides of the magnet area as the enclosure is not high enough.....
So we are constantly using pieces of 1/8 plexiglass stuffed in or bolted to the side, front and back of the table.... the problem is the plexiglass is difficult to cut or drill with out breaking it, and it is always cracking so the whole setup looks hodge podge.

Would anyone have a recomendation for a better material that is easy to cut / drill etc. but is still some form of light weight material?

Thanks!
