not my idea but something i came across that was worth re posting here. it would not be hard to make a mold to make something like this for any torch or shape you wanted but it would not be as cheap as stealing one from an oil filter. so a cheap solution to a real problem with water tables. i think it was for hypertherm torches if i remember right.

Something else that might work, but I have never seen done on a gantry:
www.lathes.co.uk/willson/
Like very wide tape measures.

A sheet steel cover that does not roll up could be passed through a slot in the gantry itself. This is something you sometimes see on lathe cross and compound slides (And on some linear actuators, such as this one thought that picture doesn't really show how the cover passes through a tunnel between the balls nut mount and the travelling part. )
