Questions about mill enclosures..

Couple questions for assembled "experts".

1. I'm looking to make an enclosure for my new Sherline 5400CNC
machine. I'm favoring Plastic and more specifically acrylic. Will
acrylic withstand cutting fluid etc or will it be attached? I'm looking to
make it a fully enclosed box with a front and back that will be hinged and
large enough to leave room to adjust and set-up the mill. Are there any
major pitfalls I should lookout for?

2. Does anyone know of a cheap and efficient coolant system for a
sherline.. if the machine is cnc I don't want to have to be applying the
coolant/lubricant. Preferable controllable...

3. Any preferred coolants out there? Are some bad for use on a Sherline?

Thanks in advance.

Ian.
