New CNC Mill on the horizon

Francis is that a cover your putting over the spindle. If so why.? . . . . Covering the whole Z axis is a good idea as it keeps debris out of screws and rails etc but I wouldn't cover spindle as it traps in heat causng cooling/pump to work harder and potential for heat expansion.

Especially true if you forget to switch on the pump or if hardwired like mine, it switches off for some reason and you don't see it. I have made a habit to check temp with hand.
Normal work will not f^^k the spindle, it heats a bit /50-55C/ but that's all. But with that cover...

Just been experimenting with cooling of these spindles and I've got it down to sealed system with no external water tank etc which all fits inside my spindle covers. Lovely and neat running lovely and cool in bench testing @ 24K going to give it a serious thrashing cutting over weekend to see if can fry it.!!

Liking the sound of that Jazz. Always looking for ways to tidy up the overall look including the plumbing. Any chance of some pictures if it works? Or even if it doesn't . . . .
