I bought some of those covers for the logitek k-360 keyboards, but the form fitted to the keys stuff could turn inside out and would hold a key down. It was much worse than just being carefull. This was on a medium sized mill, and I will have to install a lexan baffle on the left side of my sitdown operating position when I have this lathe actually making swarf. Swarf from the mill is more broadcasting it with an air hose to keep the area clean enough to see what its doing. I have a vacuum rigged for g-code control but its a constant battle to keep the nozzle in position to do a good job of sucking up the swarf as its always getting knocked out of position as the mill moves. I've made a cyclone dust separator for it, so the vacs filter stays pretty clean as better than 99.9% of it winds up in the 5 gallon plastic pail under it. > Of course a lot depends on what colour the swarf is glowing :-) With quality carbide indexable tooling, it might be orange or better since carbide is still happy at 6000F :) With more normal HSS tooling glow in the dark red. Even that will soften and degrade the edge too fast, so its wise to use a directed coolant stream with HSS tooling. Thats in the schedule at some point. :) All this stuff is bring money and I'm on SS, so its slower to accumulate the sheckels. It also means I make a lot of stuff rather than buying it. Sweat equity. ;-) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
