Thought about that but the noise would be horrible.
However I have been thinking about a canvas cover for the ways which I will try to describe because I would like opinions,
where the canvas is protecting the way it will fold around it but when off it will fold around the backsomething like this (see pic)

chipenter:
Have you looked a bellows http://www.arceurotrade.co.uk/Catalogue/Machine-Spares/Machine-Bellows , I have the rubber ones and they squash down well .

PekkaNF:
I have a little experience on dust issues on round quides.

I would start from two ideas:
* Prevent excessive fallout on quide rods, a little shield on top, maybe an ash vacumcleaner or something (you don't want to set shopvack on fire).
* keep quides dry and clean.

We had one system with plenty of abrassive dust, few hardened quide rods and plenty of ball bearing bushes. When lubricated regularry, the bushes wore out no time. They lasted about as long if they were never lubricated or lubricated with "dry" lubricant. But they life was varied even more (like factor of five) depending how often the ways were cleaned on shopvack. Claning with pressurized air was worse than no cleaning at all!

It's rally hard to prevent ingress of fine dust. IMHO non pressurized belows are not worth of it. If you get any dust/grinding paste in, it's really hard to get it out.

Commercial manual grinders seem to trust on design, that minimizes dust fall out on quides. Labyrinth seals with pressurized air purge are pretty involved.

On that type of machine I would put some shields and some wipers/lipseals to prevent any bigger that rodent size particled entering into linear bearings.

I am less worried about the linear bearings they have rubber wipers fitted and I plan to fit brushes to sweep them as the table moves along, with that I am looking into a method to block the majority of the dust even getting there in the first place. The main problem is the top of the way at the back, I am worried about a build up of dust which the bearings there will run over thus making the whole thing less accurate by whatever thickness the dust is.
Here again I am planning to use brushes the sweep the rail. the canvas Idea if I can get it to work would stop most of the dust getting there making the job of keeping the rail clean easier for the brushes.

Manxmodder:
The canvas sounds a good idea to prevent the majority of grime getting in.

I just wondered if you had also considered placing a couple of neodymium magnets in a location where they would capture a lot of the metallic dust produced while grinding is taking place......OZ.
