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.

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. ;-)
